Enfield Development Finance: 1 Unit Residential Scheme at 31 Lion Road London N9 9DN Enters the Pipeline

A small but instructive residential application has landed in the Enfield pipeline. Application 26/03491/FUL at 31 Lion Road, London N9 9DN seeks a change of use from a Use Class C3 dwelling house to a Use Class C4 house in multiple occupation, and the London Borough of Enfield planning register (Idox) shows it as 1 unit proposed, received on 18 August 2026 and still pending decision. The works include conversion of the existing garage into a habitable room, with associated amenity space, cycle storage and refuse storage.

What the scheme is

This is not a ground-up build. It is a conversion of a single family home into a small HMO, with the garage brought into the habitable footprint to add a lettable room. Our desk estimates the gross development value at around £445,000 based on the planning register details and local N9 values for a completed HMO of this type. That figure is our own estimate, not a council figure, and the eventual value will depend on room count, finish and the strength of the local rental market once the property is tenanted.

Where it sits in the Enfield pipeline

Edmonton and the wider N9 postcode have seen a steady run of C3 to C4 applications over the past two years as landlords chase higher yields than a single let can deliver. The council applies Article 4 style scrutiny to HMO conversions in parts of the borough, so approval is not automatic, and refusals on amenity or parking grounds are common where the garage loss is not properly justified. Sponsors reading our Enfield development finance page will know the borough is one of the more active outer London markets for this kind of small-scale residential work.

The finance angle

A scheme of this size sits below the radar of most mainstream development lenders, but it is bread and butter for bridging specialists and the refurbishment arms of challenger banks. The typical structure our desk would expect to see:

• A light refurbishment bridge or refurbishment-to-let facility, sized against the current value of the house, with works costs of the garage conversion and HMO compliance items (fire doors, alarms, en-suites if added) funded in arrears or held in retention.
• Day-one leverage in the 65 to 75 per cent range against the current value, with gross exposure capped at around 70 per cent of the £445,000 end value.
• A 12 to 18 month term, priced monthly, with interest retained or rolled so the sponsor is not servicing debt during the works.

The exit

The exit is the part that decides whether the numbers work. On a C4 HMO the natural route is a refinance onto a specialist HMO buy-to-let mortgage from a specialist commercial lender or challenger bank once the property is licensed and tenanted. Those lenders will value on an investment basis, so the rental figure matters more than comparable house sales. Some will require a licence in hand before completion, which can add weeks. A sale exit is possible but the buyer pool for a small HMO in N9 is narrower than for a family home.

Our read

Sponsors should line up three things before approaching a lender: the planning decision itself, since most bridging specialists will not release works funds without consent; a clear HMO licensing timeline from Enfield Council; and a refinance term sheet or decision in principle so the exit is evidenced rather than assumed. Get those in place and a scheme like Lion Road funds cleanly. Leave them loose and the bridge can run past term while the licence catches up.
