Greenwich Development Finance: 1 Unit Residential Scheme at 19 Halstow Road Enters the Pipeline

A small but instructive residential scheme has joined the borough's live caseload. According to the Royal Borough of Greenwich planning register (Idox), application 26/2003/F at 19 HALSTOW ROAD, GREENWICH, LONDON, SE10 0LD is pending decision. The register records the proposal as: conversion of 2 self-contained flats to a single family dwellinghouse; construction of single sto... The register also confirms the application was received on 06/07/2026, that 1 unit is proposed, and that the use class is residential. Our own working figure, a Construction Capital estimate drawn from the Royal Borough of Greenwich planning register (Idox), puts estimated GDV at £362,500.

What the application actually is

De-conversion schemes of this type sit awkwardly between refurbishment and development. The register's description of a two-into-one flat conversion with a single storey element attached means the sponsor is reducing unit count rather than increasing it, which changes both the valuation logic and the lending conversation. A single residential unit at completion, on a £362,500 estimated GDV, is a modest ticket by Greenwich standards, and that scale is exactly why funding it can be harder than a larger site rather than easier.

Where it sits in the local pipeline

Greenwich and the wider Woolwich corridor have absorbed a great deal of large scale, multi unit consent over recent years, and applications like this one are the quieter half of the picture: single asset works on existing stock, submitted on 06/07/2026 and still pending decision at the time of writing. We track this pipeline continuously, and the borough level detail we hold on schemes of this size feeds directly into our Greenwich development finance page, where we set out how we approach lending in the area. Small de-conversions rarely make headlines, but they represent a steady share of the borough's residential caseload and a steady share of our enquiry flow.

The finance angle

Funding a scheme of this shape usually splits into two questions. First, the acquisition or refinance of the existing building, which may already be owned and encumbered by a buy to let facility written against two flats rather than one house. Second, the build cost of the conversion and the single storey element, which is where a facility with staged drawdowns becomes worth having. Bridging specialists and specialist commercial lenders will look at this as a light refurbishment or a light development case depending on how much structural work the approved drawings ultimately require. Challenger banks tend to prefer the completed, stabilised position rather than the works period.

Our read as brokers

Our desk would want three things lined up before a decision arrives. A costed schedule of works with a contingency that reflects the single storey element, not just the internal conversion. A clear exit, whether that is sale at or around the £362,500 estimated GDV, or a term refinance onto a residential or investment product once the unit is a single dwellinghouse again. And clarity on the existing charge, because releasing or restructuring it often determines timing more than the planning decision does.

We would also encourage sponsors to have funding conditionally agreed while 26/2003/F remains pending decision, so the works can start rather than stall once consent lands.
