With its snow-white walls and Gothic turrets, this fantastical and totally restored 18th-century creation in Twickenham is the work of art historian, author and politician Horace Walpole. Studded with elaborate stained glass, the building reaches its astonishing apogee in the gallery, with its magnificent papier-mâché ceiling. For the full magic, join a twilight tour (£25). Last admission to the house is one hour before closing time.
For homemade cakes, quiche and afternoon tea (from £5), pop into the Cloister Garden Cafe (open 9.30am to 4pm Sunday to Wednesday) and don't overlook exploring the garden. The house is a five- to 10-minute walk from Strawberry Hill train station; otherwise take bus R68 from Richmond tube station.
