Thurleigh Road House

Published / verified

1. The Modern House is currently marketing the freehold house at £4.75m with five bedrooms and close to 3,500 sq ft across four lateral storeys.
2. The current instruction attributes the design to Jaam Architects and the high-specification interior finish to The Vawdrey House.
3. Jaam Architects describes this Thurleigh Road project as a pair of new-build, energy-efficient homes: one semi-detached and one detached, using heat pumps, MVHR and photovoltaics with battery storage.
4. The current instruction describes a secluded south-facing rear garden and calls the completed house Passivhaus-level; the architect says the pair achieves close to Passivhaus.
5. A working exact-property Cloudflare Stream film is exposed by the live publisher instruction and remains under publisher control.
6. The £4.75m guide divided by the near-3,500 sq ft headline area is approximately £1,357 per sq ft.
7. HM Land Registry-derived street evidence records detached sales at £5.85m in May 2025, £4.251m in May 2024 and £4.1m in March 2023; none is yet adjusted for area, condition or exact dwelling form.

Investigate next

1. Obtain the full postal address, official title registers and plans, UPRN, rights of way, covenants, easements, party-wall position and confirmation of whether the instructed house is the detached or semi-detached dwelling in Jaam's pair.
2. Reconcile the 'close to 3,500 sq ft' headline against a signed RICS floor-by-floor schedule, identifying any plant, storage, restricted-height or non-habitable space.
3. Retrieve the complete planning, condition-discharge, Building Control, completion, CIL and warranty pack for demolition/redevelopment and all subsequent changes.
4. Test the Passivhaus-level claim against PHPP outputs, certification status, airtightness results, thermal-bridge schedule, heat-pump sizing, MVHR design and commissioning, PV/battery specification and current EPC.
5. Commission an architect-led envelope, glazing, roof, drainage, structure, waterproofing, acoustics and MEP review, with installer warranties and maintenance history for the new systems.
6. Verify south-garden title boundaries, overlooking, rights, trees, landscaping obligations, surface-water strategy, utilities, broadband, parking, EV charging and refuse/access arrangements.
7. Obtain the council-tax band, rebuild-cost assessment, insurability terms and first available utility/maintenance evidence; model actual occupancy scenarios rather than relying on design intent.
8. Have a valuer adjust the street transactions for date, area, dwelling form, specification, energy systems, garden, parking and any ancillary space before drawing a price conclusion.

Still unknown

1. The protected street number, official title/UPRN and exact detached or semi-detached form are not exposed by the live instruction.
2. The bathroom count, signed net/internal area and floor-by-floor component schedule are not verified from the accessible listing evidence.
3. Passivhaus certification, PHPP design/as-built files, airtightness result, thermal-bridge evidence and commissioning records are not published.
4. Planning references, condition discharges, Building Control completion, structural documentation, collateral warranties and the new-home warranty are not connected to the protected address.
5. Council-tax band, actual operating bills, service history, insurance terms, drainage/flood evidence, ground/subsidence risk and title constraints remain unverified.
6. The street transactions lack matched floor areas and condition evidence, so no adjusted comparable range is claimed.
