Flat 9, The Tower, 55, Fitzjohn's Avenue, Hampstead, NW3 6PH

A rare NW3 landmark, this four bedroom, three bathroom duplex penthouse crowns a restored wwii watch tower, offering private ownership of the original turret itself.

Spanning the top two floors, it combines remarkable heritage with refined contemporary design, panoramic skyline views and exceptional ceiling heights.

Once the tallest point in London and later requisitioned by the RAF as a wartime lookout, the building has evolved into an exclusive residential address.

The penthouse stands as its crowning jewel, where original architectural character meets meticulous modern craftsmanship.

The expansive open plan reception and dining space is framed by far reaching views across London, enhanced by double height volumes and dramatic glazing.

A bespoke kitchen with integrated appliances and stone worktops sits at the heart of the home, designed for both everyday living and entertaining.

All four bedrooms are generously proportioned with ensuite bathrooms featuring underfloor heating and high quality finishes.

The principal suite includes a walk in wardrobe and elevated views, while the turret level provides a spectacular vantage point unlike anything else on the market.

Further enhancements include glass floor detailing and reclaimed mahogany parquet sourced from a Scottish castle, adding warmth and distinction.

Moments from Hampstead Heath, Belsize Park and excellent transport links, this secure share of freehold residence offers history, privacy and presence in equal measure.
