Bromley Development Finance: 2 Unit Residential Scheme at Lorraine Court Enters the Pipeline

A fresh application on the London Borough of Bromley planning register gives our desk another live read on bromley development finance demand, and it is a smaller conversion scheme rather than a ground-up build. Application 26/03047/FPA, received on 11/08/2026 and covering Lorraine Court at 53 The Avenue, Beckenham, BR3 5EQ, proposes converting existing loft spaces into two two bedroom flats across Blocks A and C and one one bedroom flat in Block B, for a net gain of 2 units according to the register. The works also include three dormer extensions to the east elevation of Block A, a replacement chimney and enclosed staircase extension to its south elevation, two dormers with parapet walls to Block B, an extended external metal staircase for second floor access, and three further dormers to Block C's west elevation with a matching chimney and staircase enclosure. Landscaping at the front will add 6 additional car parking spaces along with a cycle store and expanded bin storage. The scheme remains at pending decision stage.

This sits at the smaller end of the Bromley residential pipeline our desk tracks, but it is a useful one for lenders and brokers because loft conversion schemes carry a different risk profile to new build. There is an existing structure, an existing roofline, and in most cases fewer groundworks unknowns, which tends to shorten the due diligence period compared with a scheme starting from a cleared site. Construction Capital estimates the gross development value at £660,000 once the two new flats and the associated works are complete, which puts the funding requirement for a scheme of this size comfortably within the range specialist commercial lenders and bridging specialists write regularly across outer London boroughs. Sponsors looking at the wider borough context, including recent sold prices and comparable schemes, can review our Bromley area page for the local picture.

On the finance side, a conversion of this type usually needs a development or bridge to development facility structured around planning risk during the pending decision window, with drawdowns tied to the dormer and staircase works once consent is granted. Loan to GDV and loan to cost terms from challenger banks tend to flex depending on the applicant's track record with loft and roof conversions specifically, since these schemes are judged more on build risk than on land risk. Our reading is that a sponsor with a clean planning history and a realistic build programme should be able to secure competitive terms against the £660,000 GDV, provided they line up a contractor and a quantity surveyor's cost plan before submitting a funding application. We would also flag the exit: with only 2 units, a straightforward sale or refinance onto term debt is the likely route once practical completion is reached, and lenders will want that exit strategy confirmed early rather than left until drawdown.
