London Development Finance Example Scenarios

In a scheme like this, the developer might have identified a substantial Victorian warehouse within the Hackney Wick creative enterprise zone, an area that has changed rapidly since the 2012 Olympics. Buildings of this type are often vacant for several years after light industrial use, leaving them in significant disrepair. The roof structure may need full replacement, and historic commercial use can raise contamination concerns that require environmental assessment before works start. For the purposes of this example, planning permission is in place for a mixed-use scheme of 12 apartments across the upper floors and two ground-floor commercial units designated for creative workspace, in line with local planning policy. Consents of this kind often carry onerous conditions, such as a requirement to retain and restore the original brick facade and a Section 106 obligation for affordable workspace at ground floor level. From a financing perspective, the principal challenge would be the layered risk profile. The conversion is technically complex, typically requiring structural steel reinforcement, new floor plates and the careful integration of modern building services within the existing envelope. A developer experienced in residential new-build but with a limited track record in commercial conversions would face closer scrutiny from lenders. Where total project cost exceeds the developer's available equity, mainstream lenders may be reluctant to provide the required leverage given the mixed-use element and an emerging residential market at higher price points.

A typical structure here would be a blended senior and mezzanine facility of around £4.2 million, giving the developer the leverage needed to proceed without diluting equity through a joint venture. In this illustration, a senior tranche of around £3.1 million at 65% LTC would be secured against the freehold, with a mezzanine layer of around £1.1 million sitting behind it. That would bring total leverage to approximately 82% of costs and 72% of projected gross development value. A phased drawdown structure would be central. Given the technical complexity, funds would normally be released against a detailed cost plan verified by an independent monitoring surveyor. Early drawdowns would cover environmental remediation and structural stabilisation, with later tranches tied to specific construction milestones, giving both the developer and the lenders visibility that the project is tracking the approved programme. We would also look to negotiate flexible terms around the commercial element. Because ground-floor workspace units are often let rather than sold, the facility could provide for partial repayment on sale of the residential units, with an extended tail on the remaining balance to allow time for commercial lettings. This is intended to avoid a forced sale of the commercial space at practical completion. For the mezzanine layer, we would approach specialist lenders on our panel with appetite for conversion schemes in regeneration areas. A mezzanine lender in this position would commonly make its participation conditional on a minimum level of residential pre-sales, for example 30% of the units.

Structured this way, the facility is designed to fund the full 18-month programme, with contingency held in the cost plan for the technical risks of the conversion. The intended exit is repayment of the senior and mezzanine debt from residential sales proceeds, with the commercial units either sold or retained as a let investment and refinanced separately. On the indicative appraisal figures used here, the scheme would target a profit on cost of around 22%. Actual returns on any real scheme would depend on build costs, sales values, lettings and the terms available at the time. A successful outcome in a scheme like this is one where the developer completes within the facility term, repays both tranches from sales and keeps the option to retain the commercial space rather than being forced into a quick sale. For a developer new to conversions, a well-executed project of this kind can also strengthen future funding applications.

In this example, the developer is an established regional housebuilder expanding into London build-to-rent, with a site on the Greenwich Peninsula and full planning consent for a seven-storey building of 45 apartments. The location benefits from North Greenwich Underground station and views across the Thames towards Canary Wharf, but a scheme like this would present several distinct financing challenges. The most significant would be the intention to retain the completed building as a build-to-rent asset rather than sell individual units. While commercially sound where rental demand is strong, this creates a mismatch with conventional development finance, which usually relies on unit sales to repay the loan. Without a clear exit through disposal, the proposition is more complex to place. The scale of the construction programme adds further complexity. Ground conditions on the peninsula would typically require piled foundations, and a reinforced concrete frame means a longer build than a timber-frame scheme of comparable size. With an estimated construction period of around 20 months, contingency would need to allow for potential delays linked to the riverside location, including tidal considerations during groundworks. A scheme of this size would also typically carry a Section 106 agreement, in this illustration requiring 35% affordable housing delivered as affordable rent units within the main building. This reduces the net area generating market-rate income and adds complexity to post-completion management. Lenders may be cautious about the blended yield profile when affordable and market-rate units are considered together.

A typical approach would be a senior debt facility of around £12 million from a specialist lender on our panel with appetite for London build-to-rent. A 24-month term would give headroom beyond the projected construction programme, and a tail period of around six months would allow time to stabilise rental income and arrange long-term refinancing onto an investment facility. The key feature would be a dual exit mechanism. The facility agreement would permit repayment either by refinancing onto a term loan once the building is stabilised, or by disposal of the completed building to an institutional BTR investor. Showing a lender that more than one viable repayment route exists can help in securing more competitive terms. Drawdowns would be structured against an independently verified cost plan, with the monitoring surveyor inspecting monthly and certifying progress before each release. A lender in this position would commonly require a minimum equity contribution of around 25% of total project costs. We would also encourage the developer to test the institutional investment market during construction, so that indicative interest in the completed asset is understood well before practical completion. This gives the lender comfort on the exit and gives the developer a benchmark against which to judge the refinancing option. The affordable housing component could be addressed through a registered provider partnership, for example a housing association taking a head lease on the affordable units before construction starts. The capitalised value of that income would then be factored into the scheme economics and the lending case.

Structured this way, the facility is designed to carry the scheme through construction and lease-up, with the tail period giving time for the building to reach stabilised occupancy before the development loan is repaid. The aim is to move from a development facility to a longer-term investment loan once rental income is established, or to sell the completed building to an institutional investor if that offers the stronger outcome. On the indicative figures used here, the scheme would target a net initial yield of around 4.8% on the completed asset, with the affordable units handed to the registered provider partner at practical completion. Actual rents, occupancy and yields would depend on market conditions at the time of letting. A successful outcome would see the developer complete within the facility term, stabilise the building and refinance onto investment debt at a rate reflecting the lower-risk income profile. For a housebuilder new to build-to-rent, that would also provide a basis for approaching future phases.

In this example, a boutique developer specialising in high-end residential has secured a site in Richmond upon Thames: a former garden centre of around 0.4 acres on a quiet residential road within reach of Richmond Green and the Thames towpath. Planning consent is in place for six detached townhouses of approximately 2,800 square feet each across three storeys, with private gardens, integral garages and premium specification. A common complication on schemes like this is that the site acquisition has been funded with a short-term bridging loan that is approaching maturity and needs refinancing as part of the development package. That creates time pressure, as delay risks penalty interest or, in the worst case, enforcement by the bridging lender. For this illustration, total project cost including site, fees, construction and finance is taken at around £5.6 million. The developer's equity position would also be constrained. A developer with a good record of delivering premium schemes may still have capital committed across other live projects, leaving limited headroom for a conventional 70-75% LTC facility. The requirement is a structure that maximises leverage while remaining commercially viable at the target price points. Planning conditions can add further complexity. Local authorities often impose strict tree preservation requirements, for example retaining and protecting a mature London plane near the site boundary. That can constrain layout and construction method, requiring hand-digging of foundations in places and limiting heavy plant near root protection zones, adding both cost and programme risk. Lenders would also want to understand the depth of demand for new-build townhouses at an indicative price of around £1.5 million per unit, particularly if the top end of the local market has softened.

We would look to structure a stretch senior facility of around £3.8 million, providing leverage of approximately 68% of GDV and 80% of total project costs in a single tranche. A stretch senior approach avoids a separate mezzanine layer, simplifying the capital structure and typically reducing the overall cost of finance compared with a senior-plus-mezzanine arrangement. The facility would be structured to refinance the existing bridging loan at the outset, removing the time pressure. The balance would be available against the construction cost plan, with monthly valuations by a RICS-registered monitoring surveyor. A 15-month term would reflect a 12-month build programme plus a three-month sales buffer. To address lender concerns about market risk at the upper price points, we would recommend commissioning an independent Red Book valuation from a surveyor with strong knowledge of the Richmond market. The aim would be to evidence the projected GDV of around £9.2 million with recent comparable transactions and to set out the scarcity of new-build detached houses in the borough. A pre-sale covenant could also be built in, for example requiring exchange on at least two units before the final construction drawdown. This aligns lender and developer interests, encouraging early marketing and giving the lender evidence of demand before funds are fully committed. The arboricultural constraints would be managed through a detailed method statement from the contractor, agreed with the local authority's tree officer, with the associated costs built into the contingency in the cost plan.

Structured this way, the facility is designed to remove the immediate refinancing pressure on the bridging loan and fund the build through to practical completion within a single, simpler debt tranche. The pre-sale covenant is intended to give early evidence of demand, and repayment would come from the sale of the six houses. On the indicative figures used here, with a GDV of around £9.2 million, the scheme would target a profit on cost in the region of 24%. Actual outcomes on any real scheme would depend on build costs, sales values and market conditions at the time. A successful outcome would see the protected tree retained, the houses delivered within the 15-month term and the facility repaid from sales proceeds, leaving the developer's remaining equity free for its other projects.

In this example, the developer has assembled three adjacent commercial properties on a prominent Croydon high street frontage: a former bank branch, a vacant retail unit and a two-storey office building, acquired separately over around 18 months. The consolidated site offers the opportunity for a substantial mixed-use scheme in an area that has seen significant public and private investment, including improvements around East Croydon station. For this illustration, planning consent is in place for a six-storey building of 28 apartments above three retail units and a restaurant space at ground floor. The scheme includes 25% affordable housing through shared ownership, together with a communal roof terrace and concierge area. The financing challenge would be multifaceted. Total development cost is taken at around £12.2 million, including aggregate site costs of around £3.8 million. With developer equity of approximately £3.7 million, around £8.5 million of external finance would be needed, a level of leverage beyond many senior lenders' comfort for a scheme in Croydon, where residential values sit below inner London levels. The mixed-use element would add complexity. Retail lettings in Croydon town centre have been challenging in recent years, and lenders are typically cautious about underwriting commercial income projections in that environment. A restaurant unit needing specialist fit-out would usually require a pre-let or strong evidence of demand before a lender gives it value. Demolition and construction would also need care. Existing structures next to occupied buildings, such as a listed terrace to the rear, would need careful demolition, party wall agreements with several adjoining owners, and a foundation design that deals with varied ground conditions across the original plots.

A typical structure would be a combined senior and mezzanine package of around £8.5 million. In this illustration, a senior facility of around £6.2 million at 60% of GDV would come from a specialist development lender on our panel with appetite for Croydon, and a mezzanine tranche of around £2.3 million from a private credit fund, bringing total leverage to around 70% of GDV and 78% of total costs. The facility would reflect the phased nature of the works, with an initial tranche for demolition and enabling works and later drawdowns tied to milestones verified by the monitoring surveyor. We would also recommend ring-fencing the commercial and residential elements within the cost plan, so that residential construction does not cross-subsidise any overrun on the commercial fit-out. To address lender concerns on the commercial space, a priority would be securing a pre-let on the restaurant unit, for example through an agreement for lease conditional on practical completion. That would materially improve the commercial income profile and support the mezzanine lender's view of the blended scheme economics. For the remaining retail units, rent-free incentives could be budgeted within the appraisal to attract tenants. The affordable housing could be structured through a registered provider agreeing to buy the seven shared ownership units off-plan at an agreed price. A contracted receipt of this kind reduces sales risk and allows the monitoring surveyor to recognise it within periodic valuations. Lenders would also commonly look for a performance bond from the main contractor, providing additional security if the contractor became insolvent during the build.

Structured this way, the facility is designed to fund demolition and construction over the 22-month term, with the registered provider contract and a restaurant pre-let reducing reliance on open-market sales and speculative retail lettings. Repayment would come from private residential sales, the affordable housing receipts and either a sale or refinance of the let commercial units. On the indicative figures used here, with a GDV of around £18 million, the scheme would target a profit on cost of around 19%. Actual sales values, lettings and returns on any real scheme would depend on market conditions and delivery. A successful outcome would see both tranches repaid from sales and commercial value within the facility term, with the commercial units let on sustainable terms that support the wider high street.

In this example, the developer has identified a mid-floor suite of approximately 6,200 square feet within a 1980s commercial building near the Barbican. The previous tenant has consolidated into smaller premises following a move to hybrid working, and the owner is motivated to sell given rising vacancy in the building. The illustration assumes Prior Approval has been obtained under Permitted Development rights for conversion into eight apartments without a full planning application. This route offers speed and certainty but also limitations, notably the inability to extend externally or materially change the elevations, which constrains the residential layouts. The primary financing challenge would be speed. A seller in this position might agree a price of around £1.4 million for the long leasehold interest, but only on a 28-day exchange and 28-day completion. That timetable rules out conventional development finance, which typically needs 8-12 weeks for due diligence and credit approval. The developer would need immediate acquisition funding followed by a seamless move into development finance for the works. The conversion itself, though not structural, would involve substantial mechanical and electrical works: stripping out raised floors and suspended ceilings, installing new plumbing stacks and individual heating systems, and providing acoustic separation to meet Building Regulations Part E. Single-aspect windows on one side of the building could leave some apartments with limited natural light, requiring careful design to protect value. The City of London Corporation has historically sought to protect office floorspace, so the developer would need to manage the Prior Approval and building control processes carefully. Ongoing service charge obligations to the freeholder would also need to be built into the appraisal.

A typical approach would be a two-stage financing strategy combining speed on the acquisition with certainty on the works. The first stage would be a bridging loan of around £1.15 million, sized and timed to meet the seller's exchange and completion deadlines. Bridging pricing reflects the speed premium but can remain viable where the scheme economics are strong. The second stage would be a development exit facility of around £950,000 to refinance the bridge and fund the conversion. We would look to run the credit process for this facility in parallel with the bridge, aiming for approval in principle before the acquisition completes so there is no funding gap and strip-out can begin on possession. The combined facility of around £2.1 million would represent approximately 58% of the projected £6.8 million GDV. Modest leverage of this kind reflects a prime location, a lower-risk internal conversion and a developer with a strong equity position. To address the single-aspect units, the developer would benefit from design input from specialists in compact urban living. Measures such as removing the suspended ceiling grid to increase ceiling heights, adding full-height glazing where possible and specifying a high-quality finish can help position the apartments towards the upper end of the City market. The development exit facility could also allow repayment unit by unit as sales complete, reducing the outstanding balance and interest cost progressively during the sales period.

Structured this way, the finance is designed to let the developer meet a tight acquisition deadline and move straight into a development facility, without a gap between the two. With an internal-only scope and no structural alterations, the works programme would be relatively short, leaving time within the 14-month combined term for sales. On the indicative figures used here, with a GDV of around £6.8 million and relatively low leverage, the scheme would target a profit on cost of around 31%. PD conversions can carry higher target margins than new-build, but actual sales values and returns on any real scheme would depend on the finished specification, market conditions and the pace of sales. A successful outcome would see the bridge refinanced smoothly, the apartments sold within the term and both facilities repaid from sales proceeds.

In this example, the site is a 1.8-acre former local authority estate in Barking that has been decanted and cleared as part of the borough's regeneration strategy. Estates of this era are often judged no longer fit for purpose because of maintenance issues, poor thermal performance and layouts that contribute to anti-social behaviour. The council, with vacant possession, is seeking a development partner to deliver a mixed-tenure scheme. The developer here is a mid-sized housebuilder with a presence in east London, selected through a competitive tender. The illustrative scheme comprises 85 units across four blocks of four to six storeys, with a tenure mix of 40% affordable rent, 20% shared ownership and 40% private sale, plus landscaped communal gardens, a residents' room and a new pedestrian route towards Barking town centre and station. The financing requirement would be substantial. Total development cost is taken at around £20.8 million, including construction costs of around £16.5 million, fees, Section 106 contributions and a land payment structured as deferred consideration linked to viability. With developer equity of around £5.8 million, a funding gap of approximately £15 million would need to be filled. The blended tenure mix would challenge conventional development finance. Affordable rent and shared ownership units produce lower per-unit values than private sale, compressing the scheme margin, so lenders need to be satisfied that the cross-subsidy model works without eroding the developer's return below viable levels. Ground conditions on former estates can add further complications, such as made ground, redundant drainage, old foundations and possible contamination from earlier industrial use. In this illustration, a Phase 2 ground investigation identifies remediation works of around £480,000, adding cost and programme risk to the early stages. With a construction programme of around 24 months plus a sales period, the scheme would also carry meaningful market risk, including at the affordable end, where grant funding and registered provider appetite can shift with government housing policy.

We would look to structure a financing package of around £15 million with two complementary elements: around £4.5 million of JV equity from a specialist residential development fund, and around £10.5 million of senior debt from a lender with appetite for affordable-led regeneration in London. The JV equity would be central to viability. The equity investor would co-invest alongside the developer through a special purpose vehicle, sharing risk and profit on the private sale element. A typical arrangement would give the developer management control, with the investor receiving a preferred return followed by a profit share above a hurdle rate. This allows the scheme to proceed without over-leveraging the developer. The senior debt of around £10.5 million would be structured over a 30-month term to reflect the extended build and sales period. Drawdowns would be phased across the four blocks, with later blocks starting at staggered intervals so that early sales from completed blocks can start reducing the loan balance before the full facility is drawn. A crucial element would be securing contracts with registered providers for the affordable housing before financial close, covering the 34 affordable rent and 17 shared ownership units at agreed prices. Contracted receipts of this scale, around £11.2 million in this illustration, give the senior lender meaningful downside protection and support more competitive pricing. The deferred land payment could include a viability review mechanism, so that land cost adjusts if actual sales values diverge materially from the appraisal. This aligns the interests of the council and the developer and adds a further layer of protection against market risk. Remediation would be funded from the initial senior drawdown, and lenders would typically expect an environmental insurance policy covering unforeseen contamination liabilities.

Structured this way, the package is designed to fund a phased delivery over the 30-month term, with sales from earlier blocks and the contracted registered provider receipts used to reduce the senior debt as later blocks are built. Repayment would come from a combination of affordable housing receipts and private sale proceeds, with the JV investor then receiving its preferred return and profit share. On the indicative figures used here, with a GDV of around £32 million, the scheme would target a developer profit of around 16% on total costs. That is a lower margin than a purely private scheme, reflecting the 60% affordable housing content and the de-risking provided by the contracted receipts. Actual returns on any real scheme would depend on build costs, private sales values and policy conditions. A successful outcome would see all four blocks delivered within the facility term, the affordable homes handed to the registered providers and the senior debt repaid in full, with the viability mechanism protecting both the council and the developer if values move.

In this example, the developer has identified a narrow infill plot on a residential street in Islington, between two Victorian terraced houses. The site is around 28 feet wide and 65 feet deep, previously occupied by a single-storey workshop and left vacant, partly because of its tight dimensions and partly because of the complexity of building between two occupied homes with shared party walls. For this illustration, planning permission is in place for a four-storey building of four apartments: two one-bedroom units of around 550 square feet on the lower floors and two two-bedroom units of around 780 square feet above. The contemporary brick design responds to the Victorian streetscape while reading as a modern insertion. The financing challenge would centre on the tight site and its effect on programme and cost. A narrow frontage means materials and plant must be delivered and stored within a very limited footprint, ruling out methods that rely on large site compounds. A contractor might propose a hybrid approach, using a structural steel frame with precast concrete floor planks, to minimise wet trades and shorten the on-site programme. Party wall agreements with both neighbours would be required under the Party Wall etc. Act 1996, and on sites like this the process can be protracted. Extensive schedules of condition and cautious surveyors can add months to pre-construction and meaningful professional fees, around £45,000 in this illustration, which must be absorbed within the budget. The developer here is a relatively new entrant to London, with two smaller projects behind them. A limited track record can make some lenders reluctant to lend at the leverage required. With equity of around £500,000, the developer would need around £1.8 million of external finance against a total development cost of around £2.75 million. Islington buyers also tend to have high expectations on specification and finish, so the product would need to compete with high-quality period conversions and boutique new-builds while keeping costs tightly controlled on a margin-sensitive scheme.

We would look to structure a stretch senior facility of around £1.8 million, providing leverage of 65% of GDV and approximately 75% of total development costs in a single tranche. On a scheme of this size, avoiding a mezzanine layer matters, as the incremental cost of a second tier of debt could materially erode the developer's margin. The natural fit would be a specialist development lender on our panel with appetite for well-designed infill schemes in prime London locations. To support the case despite a limited track record, we would present a full information package: the planning file, detailed construction methodology, the contractor's programme and comparable new-build sales evidence from nearby. A 12-month term would reflect a compressed construction programme of around 8 months enabled by the hybrid steel-and-precast method, with a buffer for sales. Marketing off-plan from around month three would aim to generate early interest and, ideally, exchanges before completion. Drawdowns would be monthly against certified interim valuations, with the monitoring surveyor confirming progress against the approved programme and cost plan before each release. A contingency of around 10% would be held in the cost plan for issues arising from the constrained site or the party wall interface. To offset the limited track record, a lender would commonly require a personal guarantee from the developer's principal and possibly additional security, such as a charge over an unencumbered investment property. Additional security of this kind can help a newer developer access pricing closer to that offered to established developers. Early input from a sales agent who knows the local new-build market would also help set pricing and guide specification choices for the likely buyers, such as young professionals and downsizers.

Structured this way, the facility is designed to fund the build within a single, lower-cost debt tranche, with the contingency available to absorb the kind of unforeseen ground issues that are common on tight urban sites, such as uncharted drainage. Off-plan marketing during construction is intended to reduce reliance on post-completion sales, with repayment coming from the sale of the four apartments. On the indicative figures used here, with a GDV of around £4.5 million, the scheme would target a profit on cost of around 28%. Actual sales values and returns on any real scheme would depend on build costs, specification and market conditions. A successful outcome would see the building delivered within the 12-month term and the facility repaid from sales. For a newer developer, a well-executed scheme of this kind can also strengthen its track record when seeking funding for future projects.
