1937 character residence comprehensively modernised by the current owners; kitchen by Expresso Design London; landscape designer unnamed

Detillens Lane Residence
Detillens Lane, Oxted, Surrey
Independent reading
A 1937 Oxted house comprehensively reworked around a 6,339 sq ft family plan, design-led kitchen, landscaped grounds and an Endless swimming pool.
Detillens Lane Residence clears Aveno's outstanding-modernisation gate through the depth of its current-owner upgrade, coherent design specification, substantial detached scale and integrated landscape-and-pool programme. The £2.95m guide divided by the 6,339 sq ft headline is about £465 per sq ft, but that denominator must not anchor value until a signed component schedule separates habitable accommodation, integral garage, pool and plant space and the full approvals archive is reconciled.

- Fine & Country's original instruction is live with an active viewing route at £2.95m and records a detached, chain-free, freehold house with five bedrooms, three bathrooms, three receptions, 589 sq m and a 1,230 sq m plot.
- The house dates to 1937 and the listing attributes a comprehensive high-level modernisation by the current owners, including oak flooring, underfloor heating to the ground floor and principal bedroom, and Lutron lighting.
- Expresso Design London is credited for the open-plan kitchen with Sapien Stone worktops and Miele, Gaggenau and Bora appliances; glazing and bifolds connect the principal rooms to the south-east-facing terrace.
- The landscaped grounds include an Endless swimming pool, deck, barbecue and pizza-oven area, mature planting and an attached double garage.
- The listing exposes an exact-property Instagram Virtual Tour. Aveno embeds only Instagram's remote publisher player and reproduces no estate-agent still, screenshot, photograph or floorplan.
- The £465 per sq ft figure is arithmetic only: £2.95m divided by the listing's approximate 6,339 sq ft headline area. It is not an adjusted valuation or a claim that every component has equal utility.
- Current England main-residence SDLT at £2.95m is £267,750 before buyer-specific higher-rate, non-resident, relief or mixed-use treatment.
Investigate next
- Obtain the numbered address, official title register and plan, UPRN and measured plot, then reconcile boundaries, access, covenants, easements, services, drainage, trees and every shared or private-lane obligation.
- Retrieve the complete planning, Building Control and works chronology for the modernisation, kitchen and structural openings, pool, terrace, external works, glazing, garage and building-services changes, including approved drawings, conditions, completion certificates, warranties and professional appointments.
- Commission a signed RICS component measurement separating habitable rooms, circulation, integral double garage, pool/deck interfaces, plant and any restricted or ancillary area before using the 6,339 sq ft denominator.
- Commission structure, roof, façade, glazing, waterproofing, underfloor heating, air-conditioning, Lutron controls, gas fires, pool plant, drainage and electrical surveys, with service records, warranties and costed remedial priorities.
- Obtain three years of energy, water, pool, grounds, security, insurance and maintenance records, plus the complete EPC, current Band G charge and property-level flood, ground, radon, subsidence, tree, drainage and insurance reports.
- Have a valuer adjust the same-lane transactions for date, area, condition, plot, pool, garage and the subject's modernisation before drawing a price conclusion.
