Belsize Park Gardens, Hampstead NW3

Mansion flats were built for people moving from large houses who did not want to give up the rooms, and this one shows why they are still sought after. Every room opens off a central hall, ceilings are over three metres high and the reception and dining rooms are joined by double doors.

The flat has been decorated with care, with panelled walls, a pale blue reception room and a kitchen large enough for a family table. Both bedrooms face the quiet gardens at the back, and the principal has a bathroom with a copper roll-top bath.

The building has a lift, a resident porter and well-kept gardens. The flat comes with a share of the freehold and a 999-year lease. Belsize Park station and the village shops are five minutes' walk.
