Enfield Development Finance: 1 Unit Residential Scheme at 17 Cunningham Avenue Enfield EN3 6LB Enters the Pipeline

Enfield development finance is back in focus this week after a fresh planning application landed on the London Borough of Enfield register. Application 26/03184/FUL, covering 17 Cunningham Avenue, Enfield EN3 6LB, seeks a change of use from Use Class C3, an ordinary dwelling house, to Use Class C4, a house in multiple occupation, with associated amenity, cycle and refuse storage. Per the London Borough of Enfield planning register, held on the Idox system, the application was received on 27 July 2026 and remains pending decision.

It is a single unit scheme, which places it at the smaller end of what we see cross our desk, but small does not mean simple. HMO conversions carry their own regulatory and management overheads, from room size standards to licensing, and lenders price that complexity into their terms even on a one property job. Construction Capital estimates the gross development value of the finished scheme at £445,000, based on the planning register data, and that figure is the anchor for how a lender will size any facility against it.

This application sits within a steady flow of residential conversion activity across the borough. Enfield has become a consistent source of small scale C3 to C4 change of use applications as landlords and developers look to increase rental yield from existing housing stock without the cost and risk of a full new build. Readers following the wider pipeline can see how this scheme compares against other live schemes on our Enfield development finance page, where we track applications across the borough alongside funding routes for each.

From a funding perspective, a single unit HMO conversion of this size typically sits with specialist commercial lenders and bridging specialists rather than the high street. Facilities for this type of scheme are commonly structured on a loan to cost basis during the works phase, with lenders often advancing up to around 65 to 70 percent of cost, before a term or refinance facility takes the completed asset through to stabilised income. Against a £445,000 GDV, a sponsor should expect a lender to stress test both the build budget and the exit, particularly given how quickly local HMO rental comparables can move.

Our read as brokers is that the fundamentals here are workable but the timeline needs planning early. Change of use applications from C3 to C4 can attract local objections around parking and amenity, so sponsors should not assume a smooth run to decision. We would encourage anyone with an interest in this site, or a similar single unit HMO conversion elsewhere in the borough, to get funding terms indicative ahead of a decision notice rather than after, since bridging specialists and challenger banks both need lead time to underwrite change of use risk properly. Getting a facility agreed in principle before planning consent lands can shave real weeks off completion once the decision notice is issued, which matters on a scheme of this scale where holding costs eat into margin quickly.

We will continue to monitor this application through to decision and update our Enfield tracking accordingly.
