Ealing Development Finance: 2 Unit Residential Scheme at 139 Lady Margaret Road Southall UB1 2PS Enters the Pipeline

A new small residential application has landed on the Ealing planning register, and it is exactly the sort of scheme our desk sees funded week in, week out across west London.

The application

Application 262904FUL, received on 27 July 2026 according to the London Borough of Ealing planning register, proposes the conversion of an existing dwellinghouse at 139 Lady Margaret Road, Southall UB1 2PS into two self-contained flats, together with a ground floor rear infill extension. The use class stays residential. The application is currently pending decision.

Two units is a modest scheme by any measure. Our own estimate puts the gross development value at around £750,000 once both flats are complete and ready for sale or letting. That figure is based on the register entry and local comparables, not on any valuation attached to the application itself.

Where it sits in the Ealing pipeline

Southall has a steady flow of house-to-flat conversions coming forward, and this one fits the pattern: a single dwelling on a residential street, extended at the rear to add floorspace, then split into two homes. Schemes of this size rarely make headlines, but they make up a large share of the applications we track on our Ealing page, and they are often the first project for a new sponsor.

The finance angle

A two-flat conversion with a rear infill extension will normally need funding at two points.

First, site finance. If the sponsor does not already own the property outright, or holds it on a standard residential mortgage that does not permit works of this kind, a bridging loan is the usual route to buy or refinance the house while planning is determined. Bridging specialists will lend against the existing value, typically to somewhere between 65 and 75 percent, with planning risk priced in.

Second, the build. Once consent is granted, a light refurbishment or small development facility from a specialist commercial lender can release the works cost in stages against monitored progress. On a scheme of this size, some bridging specialists will fund purchase and works under a single facility, which keeps arrangement costs down and avoids a second set of legal fees.

Then comes the exit. With a £750,000 GDV split across two flats, the sponsor has two realistic routes: sell both units and repay the facility from proceeds, or retain them and refinance onto a buy-to-let mortgage with a challenger bank or specialist lender. A development exit bridge is also available if the flats are finished but sales are slower than hoped, giving the sponsor time to achieve a better price rather than accept a discounted one to clear the loan on term.

Our read

The application is pending, so nothing is certain yet, but sponsors on schemes like this should be lining up three things now rather than waiting for the decision notice.

One, a clear cost plan for the extension and conversion, broken down by trade, because lenders on small facilities will scrutinise the works budget more than the GDV. Two, evidence of the exit, whether that is comparable flat sales on nearby streets or an agreed rental figure that supports a refinance. Three, a credible contractor with a track record on conversions, since lenders will ask who is delivering the works and on what terms.

Our desk can run indicative terms on a two-unit conversion in Southall within a working day. If you are the sponsor behind 262904FUL, or you have a similar scheme elsewhere in the borough, speak to us before consent lands so the funding is ready when the works can start.
