A Double-Floor Penthouse Within a WWII Watch Tower - Own an Icon of History and Architectural Excellence

A rare opportunity awaits in the heart of NW3 - a chance to own not just a home, but a living piece of British history.

Positioned at the very top of one of London's most historically significant buildings, The Tower is a three-bedroom, three-bathroom duplex penthouse that offers the ultimate in luxury, exclusivity, and character. Set within the restored WWII watch tower, this exceptional residence combines heritage and modernity in an extraordinary architectural feat - offering full and private ownership of the original tower structure itself.

Historic Legacy, Modern Living

Once used as a strategic vantage point during the Second World War, The Tower has since been thoughtfully reimagined into a collection of luxury residences - as its crowning jewel. The penthouse spans the top two floors of the building, with every detail meticulously crafted to balance the gravitas of its historical past with the sophistication and comfort of contemporary living.

From the moment you enter, you are met with double-height ceilings, elegant staircases, and panoramic views that sweep across the London skyline. Original architectural features have been preserved and celebrated, while state-of-the-art finishes, materials, and systems ensure effortless, modern-day functionality.

Sophisticated Interiors & Elevated Design

The interior layout has been carefully designed to maximise both space and natural light. The expansive open-plan reception and dining area is ideal for entertaining, framed by large windows that capture dramatic, uninterrupted vistas across the city. The bespoke kitchen features high-end integrated appliances, stone worktops, and sleek cabinetry - perfect for culinary creativity or hosting guests.

All three bedrooms are generously proportioned, with en-suite bathrooms boasting spa-like finishes, underfloor heating, and designer fittings. The principal suite offers an indulgent retreat, complete with walk-in wardrobe, bespoke joinery, and its own elevated view over London.

A Home That Tells a Story

Perhaps most uniquely, The flat grants exclusive ownership of the full watch tower, an architectural landmark rarely offered on the open market. It is more than a residence; it is a symbol of resilience, heritage, and timeless design, now reborn as a private sanctuary in one of London's most desirable postcodes.

Location

Situated in NW3, The Tower enjoys proximity to the green expanses of Hampstead Heath, the charming boutiques and restaurants of Belsize Park, and excellent transport links into Central London. Despite its central location, the property remains a quiet, secure, and private oasis high above the city.
