Bromley Development Finance: 2 Unit Residential Scheme at 30A High Street Enters the Pipeline

Bromley development finance is back in focus after a fresh application landed on the borough's planning register for 30A High Street, West Wickham, BR4 0NJ. The application, reference 26/03166/FPA, proposes converting an existing first and second floor maisonette into two self-contained flats: one 1-bed and one 2-bed. According to the London Borough of Bromley planning register, held on the Idox system, the application was received on 13 August 2026 and is currently pending decision.

It is a small scheme by unit count, just 2 units, but it is a useful marker of what is moving through the West Wickham pipeline right now. Construction Capital estimates a gross development value of £660,000 for the completed scheme, based on our reading of the planning submission. That figure gives sponsors and lenders a working benchmark for a conversion of this type in this part of the borough, and it is the kind of small-site data point our Bromley market page tracks across the wider area, alongside pricing trends and other live applications.

On the finance side, a scheme like this sits squarely in bridge-to-development or light refurbishment territory rather than a full ground-up facility. Converting an existing maisonette into two flats is not structural new build, so lenders will typically look at it as a permitted development or change of use style project, with funding drawn down against the works rather than against a build programme with foundations and superstructure stages. At a £660,000 GDV, we would expect specialist commercial lenders to size a facility against a loan to gross development value in the region of 60 to 70 per cent, with drawdowns released as the conversion works complete and building control sign-off is obtained on each stage.

The bigger question for a scheme this size is usually the exit, not the entry. Two flats sold individually or held as a small buy-to-let block both work, but the finance needs to match the plan from day one. A sponsor who funds the works on a development facility and then wants to refinance one flat onto a term buy-to-let mortgage while selling the other needs that split agreed with the lender before drawdown starts, not after practical completion. Bridging specialists are usually more comfortable with this kind of mixed exit than challenger banks, who tend to prefer a single, clean outcome across the whole security.

Our read as brokers is that decisions of this size in West Wickham tend to move through committee reasonably quickly given the modest unit count and the fact that the works sit within an existing building envelope rather than adding new floors or footprint. Sponsors watching 26/03166/FPA should use the time before determination to get facility terms indicatively agreed, not to wait for consent before making a single call. Lenders want to see a realistic build cost schedule against that £660,000 GDV, a clear view on whether the exit is a sale, a refinance, or a mix of both, and evidence the applicant has capacity to fund the deposit and any early stage costs before the first drawdown lands. Getting those three points settled now means completion is not held up once the decision notice arrives, and it keeps this small but useful scheme moving at the pace the wider Bromley pipeline is currently setting.
