Grade II listed country house with a circa-1800 principal block and earlier service fabric; original architect is not recorded in the statutory entry

Woodhill House
Brookmans Park, Hertfordshire, Hertfordshire
Independent reading
A 4,607 sq ft wing of a Grade II listed Hertfordshire country house, modernised around six bedrooms, a sweeping lantern-lit stair, south-facing gardens, heated outdoor pool and double garage.
Woodhill House clears Aveno's outstanding-modernisation route despite not being detached: the 4,607 sq ft private wing combines nationally listed architecture with a complete contemporary family programme, four en-suite bedrooms, modern kitchen and bathrooms, pool, pool house, gated grounds and EV-ready garaging. The £619/sq ft headline is only a blended entry signal. The offer turns on the divided-building title and 999-year lease, listed-building consent history, EPC G operating burden, private drainage and pool condition—not on the Georgian presentation alone.

2 Woodhill House, Kentish Lane, Hatfield
Hopcroft's live original instruction identifies 2 Woodhill House on Kentish Lane and embeds the exact-property film; its current inventory and social publication supply the full AL9 6JY address. The exact-address property record connects UPRN 100081158069, EPC G, approximately 428 sq m and the January 2004 transaction. Historic England independently identifies the listed Woodhill House on Kentish Lane. The title, lease plan and precise extent of number 2 inside the divided mansion remain buyer-side.

- Hopcroft currently offers 2 Woodhill House at offers over £2.85m with an active enquiry route, six bedrooms, five bathrooms, four receptions and semi-detached marketing classification.
- The current joint-agent particulars attribute a 999-year lease from 1989 with a share of freehold, £175 monthly service charge, Council Tax Band H, EPC G, Calor gas and private drainage to a Klargester treatment plant.
- The exact-address EPC-derived record attributes approximately 428 sq m / 4,607 sq ft and UPRN 100081158069; a signed component measurement and official UPRN-title bridge remain required.
- Historic England lists Woodhill House at Grade II and dates the main block to circa 1800, with seventeenth-century or earlier fabric in the service wing. This conflicts with the marketing statement that the residence dates to 1753.
- The modernised programme includes a principal suite with a large dressing room, four en-suite bedrooms, two further bedrooms, landscaped south-facing gardens, heated outdoor pool, pool house, double garage and EV charging.
- The working Hopcroft exact-property film remains available inside the publisher-controlled YouTube player; Aveno reproduces no listing photograph, film still, screenshot, floorplan or footage.

- Retrieve the full 2023 EPC and commission property-level surface-water, groundwater, sewer, ground, tree, access, noise and insurance searches; cost a conservation-compatible pathway out of EPC G before valuing any energy improvement.

All property film and photography remain publisher-controlled. Only the live film player and original Aveno evidence graphics are permitted; social stills require separate written permission. Hopcroft's live original instruction embeds its working exact-property Woodhill House film in the publisher-controlled YouTube player. The full AL9 6JY address, gated Georgian house, six-bedroom programme, modernised interiors, pool and country setting align across the instruction and film. Aveno uses only YouTube's privacy-enhanced player and copies, downloads, screenshots, rehosts and hotlinks none of the film or estate-agent photography. The dossier retains an Aveno evidence panel and direct publisher/source links if the remote player is unavailable; no broken-image panel is rendered.
