Derwydd Mansion is an exceptionally rare Grade II* Tudor mansion dating from the early 1400s, set within approximately eight acres of mature, private grounds. The house retains significant original features — stained glass, oak fireplaces, plasterwork and wood-beamed rooms — and carries an important historical association with the Tudor period. The property comprises extensive accommodation across multiple storeys with 14 bedrooms and flexible reception space, offering obvious potential for a high-end family residence or commercial conversion (subject to consents).
The estate has a proven track record of alternative uses, having previously operated as a wedding venue, holiday complex and film location. That operational history underlines commercial potential for events, hospitality or multi-unit accommodation, but any change of use or works will be constrained by the building’s listed status and individually listed interior and exterior features. The sale is freehold and the house is offered with many of the original contents and artefacts, which may support a turnkey transition for specialist purchasers.
Prospective buyers should note material practical considerations: the Grade II* listing imposes strict consent requirements and may complicate alterations or modernisation; substantial ongoing maintenance will be required for a building of this age and scale; broadband speeds are very slow and mobile signal is only average; the local area registers as very deprived which may affect staffing, rental market and grants; council tax is described as quite expensive. There is no flooding risk and the plot is huge, with formal lawns, walled garden, gazebo and garage parking.
This property will suit a buyer seeking a high-profile historic asset with scope for sensible adaptive reuse and long-term value creation — experienced developers, heritage custodians or multi-generational families who accept listed-building responsibilities. Legal and survey advice is essential before committing, and any intended commercial use will require planning and listed-buildings consent.
