Confidence: MEDIUM
This is a substantial detached-house project with a lot to work with: four reception rooms, a detached double garage, broad driveway and an unusually long, established garden. The photographed interiors are usable but dated, giving scope to rework the kitchen and bathroom and refresh finishes across several rooms; the exterior and roof look generally maintained, with no obvious major defect in the available views. The listing also mentions further extension potential, subject to planning permission.
The price is the sticking point. At £603/sq ft, the £1.5m asking price is around 14% above the local average of £528/sq ft. Adding the stated £55,000–£95,000 renovation range puts the purchase-plus-works cost at roughly £1.555m–£1.595m, stretched against the local benchmark for this floor area. That comparison is with today’s local average, not a forecast of post-renovation value, so the generous space and garden need to justify the premium for this to stack up.
Key opportunities
- Modernise the dated kitchen, bathroom and finishes across several rooms to create a more contemporary interior.
- Make use of the four reception rooms, four bedrooms and detached double garage to shape a flexible family home.
- Improve the established 170-metre garden for outdoor living; the listing also cites possible extension potential subject to planning permission.
Key risks
- At the asking price, even the stated refurbishment range leaves purchase-plus-works costs well above the local average benchmark for this floor area, before fees or other purchase costs.
- All-in spend is likely to land near £1,575,000 when purchase and the £75,000 refurb range are added together, leaving a gap of around 17% versus area norms for this sqft; post-works value sits outside our data.
