Enfield Development Finance: 1 Unit Residential Scheme at 61 Lancaster Road London N18 1HP Enters the Pipeline

Enfield development finance is back in the spotlight after a new application landed on the council's planning register for a single residential unit at 61 Lancaster Road, London N18 1HP. Reference 26/03374/FUL, received on 10 August 2026 according to the London Borough of Enfield planning register, is currently pending a decision and proposes changing the property's use from a standard dwelling house (Use Class C3) to a house in multiple occupation (Use Class C4).

The works behind that change of use are not trivial. The scheme involves a single storey side and rear extension, removal of the existing rear outbuilding, conversion of the rear dormer to an outrigger dormer, and new front roof lights, alongside associated amenity, cycle and refuse storage. It is a one unit scheme on paper, but the scope of alteration, extension, roof works and outbuilding demolition means the build cost will look more like a full refurbishment than a light conversion. Per our own estimate drawn from the planning register, the completed scheme carries a projected gross development value of £445,000, which gives sponsors a workable ceiling to plan borrowing against.

This is a useful marker for where the wider N18 pocket of the borough sits in the Enfield pipeline. Small HMO conversions of this kind have become a steady feature of the area as landlords and developers look to squeeze more income from single dwellings close to transport links and local amenities. Applications like this one rarely make headlines individually, but taken together they show a borough where planners are seeing a consistent flow of change of use and roof extension proposals rather than large scale new build. Anyone tracking the area's development finance activity, including through our Enfield location page, will recognise this as part of a broader pattern of smaller scale, HMO focused schemes across the borough.

From a funding perspective, a scheme of this size sits squarely in the territory our desk sees most often: too small for a syndicated facility, but too involved for a simple refurbishment bridge. With a £445,000 GDV and a scope that includes structural extension work, an outbuilding demolition and roof alterations, we would expect sponsors to need a light development or heavy refurbishment facility rather than a straightforward buy to let mortgage, given that lenders will want to see the build costs and contingency modelled properly before releasing funds in stages.

Our read is that sponsors on schemes like this should have their planning consent, a realistic build cost schedule and an exit strategy, whether sale or refinance onto a standard HMO mortgage, ready before they approach specialist commercial lenders or bridging specialists. HMO conversions with extension works tend to draw more scrutiny on valuation and build cost than a straight refurbishment, so a clear breakdown of the extension, dormer conversion and storage works will help keep the process moving once consent is granted. We will be watching for the decision on 26/03374/FUL and what it signals for appetite toward HMO conversions elsewhere in the borough.
