Description

Magna Carta House is a historical gem located on a secluded private island in the River Thames, enveloped by 3.73 acres of lush grounds and spanning over 402 metres of riverfront. This Grade II Listed Victorian property, constructed in 1834, is steeped in history as the believed site where the Magna Carta was signed in 1215. While this residence boasts period features like traditional beam ceilings, a grand fireplace, and a unique 'Charter Room' housing the stone linked to the historic document, it requires modernisation to align its charm with contemporary living standards (subject to planning consents). The house includes seven bedrooms, a principal suite with an en-suite bathroom and dressing room, along with multiple living areas including a drawing room and sun-room. The extensive grounds feature a swimming pool surrounded by manicured topiaries and mature trees providing privacy along the riverside. A detached garage and cottage—though needing significant renovation—offer potential for additional accommodation or guest space. This property presents an exceptional opportunity for an investor or homeowner looking to preserve its historical significance while transforming it into a modern retreat. The area is rich in royal history and offers tranquillity away from urban life yet remains conveniently located near Windsor's amenities.
