Enfield Development Finance: 1 Unit Residential Scheme at 24 Stowe Gardens London N9 9PS Enters the Pipeline

A small but instructive residential application has landed on the Enfield planning register. Application 26/03031/FUL at 24 Stowe Gardens, London N9 9PS, seeks a change of use from Use Class C3 (dwelling house) to Use Class C4 (house in multiple occupation), with associated amenity space, cycle storage and refuse storage. The application is retrospective, so the conversion has already been carried out and the applicant is now seeking to regularise it.

The application: scheme, units and status

Per the London Borough of Enfield planning register, the application was received on 17 July 2026, covers 1 unit, and is currently pending decision. The use class is residential throughout, so this is not a commercial conversion. It is a family house that has been reconfigured for shared occupation, and the council is now being asked to sign off on what is already in place.

Our desk puts the estimated gross development value at £445,000, a Construction Capital estimate drawn from the register entry and local comparables for the N9 postcode. That figure matters because it sets the ceiling for any refinance or exit facility once the planning position is settled.

Where it sits in the Enfield pipeline

Single-unit HMO conversions rarely make headlines, but they are a steady feature of the borough's housing pipeline. Edmonton and the wider N9 area have seen a run of C3 to C4 applications over the past two years as landlords respond to rental demand from workers commuting into central London and the Lee Valley employment zones. Enfield operates an Article 4 direction in parts of the borough, which removes permitted development rights for small HMOs and forces landlords through a full application. That is almost certainly why this scheme is going through the formal route rather than relying on permitted development.

We track applications of this type across our Enfield coverage because they tend to arrive at our desk in one of two states: either a landlord who converted first and is now stuck on a mortgage that no longer fits the property, or an investor looking to buy a completed HMO and needing a lender who will accept the retrospective consent.

The finance angle: what funding the scheme will need

A retrospective application changes the finance picture. Most high street lenders will not refinance a property whose use class is unresolved, and a C4 consent that is still pending leaves the borrower in limbo. The practical options are:

• A bridging facility from a bridging specialist to hold the position until the decision lands, typically at 65 to 70 percent of the £445,000 value, giving a facility in the region of £290,000 to £310,000.
• A term HMO mortgage from a challenger bank or specialist commercial lender once consent is granted, priced on rental yield rather than the owner's personal income.
• If the application is refused, a longer bridge to cover the appeal period or the cost of reverting the property to a single dwelling.

On a scheme of this size there is no construction drawdown to arrange. The money is in the exit, and the exit depends entirely on the planning outcome.

Our read and what sponsors should line up

Our view is that a single-unit retrospective HMO is a planning risk problem dressed up as a finance problem. Sponsors should have three things ready before approaching any lender: a copy of the full application including the amenity and refuse plans, evidence that the property meets the council's HMO licensing standards, and a valuation that reports on both the C3 and C4 basis so the lender can see the downside case.

Lenders in this space are pragmatic, but they will price the uncertainty. Getting the paperwork in order now, while the decision is pending, is the difference between a clean refinance in the autumn and a scramble in the winter.
