Croydon Development Finance: 2 Unit Residential Scheme at Honeywood Bishops Walk Croydon CR0 5BA Enters the Pipeline

A new upward extension scheme has landed on the Croydon planning register, and it is the kind of small residential project our desk sees funded week in, week out across south London.

The application

Application 26/02333/GPDO covers Honeywood, Bishops Walk, Croydon CR0 5BA. Per the London Borough of Croydon planning register, the proposal is an upward extension adding two additional floors over an existing two storey dwelling, delivering 2 new residential units. The application is pending decision.

The GPDO reference matters. This is a prior approval route under permitted development rights for upward extensions, not a full planning application. That usually means a tighter set of tests for the council to consider, and a shorter route to a decision than a conventional consent, although the outcome is never guaranteed and neighbour amenity, design and structural questions can still trip a scheme up.

Our own estimate puts the gross development value at £830,000 for the two units combined. That figure is a Construction Capital estimate derived from the register entry and local comparables, not a number the applicant has published, so any sponsor should test it against their own agent's advice before building a funding case around it.

Where it sits in the Croydon pipeline

Bishops Walk sits on the Shirley side of the borough, a low-rise suburban patch where airspace and upward extensions have become one of the more practical ways to add homes without acquiring new land. Croydon has a steady flow of these two-to-four unit schemes, and lenders active in Croydon are comfortable with the product as long as the numbers hold together.

The finance angle

A scheme of this size typically needs one of two things. If the sponsor already owns the house, the usual structure is a light-to-medium development facility from a specialist commercial lender or bridging specialist, secured against the existing property, with the build cost drawn down in stages against monitoring surveyor sign-off. Facilities on schemes of this type commonly run to 65 to 70 per cent of GDV, so on our £830,000 estimate the ceiling would sit somewhere in the £540,000 to £580,000 range, subject to the lender's view of value and build cost.

If the property has yet to be bought, the deal becomes a two-stage exercise: acquisition finance first, then a development or refurbishment facility once prior approval is in hand. Some challenger banks will do both under one umbrella, but most sponsors find it cleaner to bridge the purchase and refinance into a build facility once the consent is certain.

The exit is the other half of the conversation. Two units at this value point are well suited to individual sale, but sponsors who intend to keep them as lets should line up a development exit or term product early. Lenders price the exit on the finished asset, and a pre-agreed refinance removes the pressure of a sale deadline at the end of the build term.

Our read

Upward extensions are structurally more demanding than they look on paper. Lenders will want a structural engineer's report on the existing building, a fixed-price build contract or a credible cost plan, and a clear contingency line, usually 10 per cent of build cost. Sponsors should also expect a lender to check that the prior approval conditions are discharged before the first drawdown.

For anyone watching this application, the practical steps are simple: confirm the GDV with two local agents, get the build cost priced properly, and have the funding structure agreed in principle before the decision lands. That way the scheme can move the day the prior approval is granted, rather than losing weeks afterwards.
