We've tightened what earns a Pursue. A home now needs a published valuation, a strategy that still makes money after real running costs and lender stress tests, and no listing problems that would stop a mortgage. You'll see fewer Pursues, and each one has been checked harder.

About
This unique and spacious penthouse apartment offers a rare opportunity in Windsor to enjoy expansive outdoor space combined with generous rooms, modern interior design and easy access to the transport network and the historic town itself.
The apartment is bright and airy throughout, with high ceilings and dual or triple aspect to all main rooms.
The open-plan living and dining area overlooks the gardens from two Juliet balconies, and adjoins a semi-open-plan kitchen.
All three generous double bedrooms also feature Juliet balconies, with stunning views of the historic cedars and gardens.
Built-in wardrobes in every bedroom, alongside a deep hall cupboard, provide exceptional storage space, bedroom three also features a dressing room/office, and the principal bedroom has a spacious en suite with large walk-in shower and a feature freestanding bath.
A useful utility room opens from the welcoming and roomy entrance hall.
Fully refurbished by the current owners, incorporating high-end interior design and redecoration, the apartment features new flooring throughout, plus a new kitchen and bathrooms.
Lambton House was built in 2002 in keeping with the original Gothic school building that greets visitors as they enter the main gates.
It features a lift service from the penthouse floor to the secure basement garage, where the apartment benefits from two allocated parking spaces.
Further visitor parking is situated to the front of the building on the gravel driveway.
A key feature of the property is the access to the shared grounds, which include acres of lawn and field plus a historic, and recently replanted, parterre.
Situated on Longbourn, part of the gated Imperial Park development in Windsor, the apartment has excellent transport links, being just 5 minutes from the M4 and a 20 minute drive from Heathrow.
Windsor’s stations provide easy access to Waterloo and to Slough for the Elizabeth Line into the heart of the capital.
With its castle, racecourse, theatre, shops and restaurants, Windsor provides an enviable lifestyle.
Lambton House is also a short walk from the Great Park, providing miles of walking and cycling routes. EPC Rating: C
