Best Luxury New Builds in Zone 1 London
Zone 1 remains the epicentre of London’s ultra-prime property market, where new developments are defined by architecture, service infrastructure and long-term investment value. For ultra high net worth buyers, these schemes are not simply residences—they are fully serviced lifestyle assets in globally recognised postcodes.
Below is a curated selection of the best luxury new builds in Zone 1, based on design quality, developer reputation, location and buyer demand.
The OWO Residences by Raffles, Whitehall
The OWO Residences by Raffles
Located in the historic Old War Office building, this is one of the most significant luxury redevelopments in London.
The project combines branded residences with a five-star Raffles hotel, delivering a hybrid model of heritage architecture and modern ultra-luxury living. Interiors are highly detailed, with strong emphasis on craftsmanship and scale.
Residents benefit from hotel services, private dining, spa access and one of the most prestigious addresses in Westminster. This development is positioned for buyers seeking trophy assets with long-term cultural and financial value.
One Hyde Park, Knightsbridge
One Hyde Park
Although not newly completed, One Hyde Park remains a benchmark for ultra-prime new build luxury in Zone 1.
Developed by Candy & Candy, it introduced the concept of fully serviced residences in London, with features such as bulletproof glazing, private security and Mandarin Oriental services.
Its location overlooking Hyde Park continues to command some of the highest prices globally, making it a reference point for all new developments.
60 Curzon, Mayfair
60 Curzon
Positioned in the heart of Mayfair, 60 Curzon represents boutique ultra-luxury living with a strong emphasis on privacy.
The development offers a limited number of residences, ensuring low density and exclusivity. Design is contemporary yet understated, appealing to buyers who prioritise discretion over visibility.
Its proximity to Berkeley Square and Mayfair’s private members’ clubs enhances its appeal among ultra high net worth individuals.
The Bryanston, Hyde Park
The Bryanston
Designed by Rafael Viñoly, The Bryanston is one of the most architecturally distinctive new builds in central London.
Located adjacent to Hyde Park, it offers expansive lateral apartments with floor-to-ceiling glazing and panoramic park views. The development focuses on light, space and modern design, differentiating it from more traditional schemes.
It appeals to international buyers seeking contemporary architecture within a prime central location.
One Crown Place, City Fringe (Zone 1 Border)
One Crown Place
Situated on the edge of the City and Shoreditch, One Crown Place represents a newer direction in luxury development—blending residential, hospitality and workspace environments.
While slightly more design-led and less traditional than Mayfair or Knightsbridge schemes, it attracts a younger UHNW demographic looking for modern urban living with strong rental and capital growth potential.
Principal Tower, City of London
Principal Tower
Designed by Foster + Partners, Principal Tower is a high-rise development offering panoramic views across London.
The project combines strong architectural credentials with high-end amenities, including concierge services and resident facilities. It appeals to buyers seeking vertical luxury living within the financial district.
What Defines the Best Zone 1 New Builds
The strongest luxury developments in Zone 1 share several defining characteristics:
Prime micro-location, often within Mayfair, Knightsbridge or Westminster
Low-density layouts, ensuring privacy and exclusivity
Branded or serviced living, integrating hotel-level amenities
Architectural distinction, often led by globally recognised designers
Security and discretion, tailored for UHNW residents
These factors collectively drive both lifestyle value and long-term capital appreciation.
Investment Perspective
Zone 1 luxury new builds continue to attract global capital due to:
Limited supply of new developments in prime locations
Strong demand from international buyers
Currency-driven investment opportunities
Long-term resilience of central London real estate
Branded residences and heritage redevelopments, in particular, are expected to outperform due to their rarity and positioning.
Conclusion
The best luxury new builds in Zone 1 London are defined by more than location. They represent a convergence of design, service and global prestige.
Developments such as The OWO Residences and 60 Curzon prioritise exclusivity and heritage, while projects like The Bryanston and Principal Tower introduce modern architectural perspectives.
For ultra high net worth buyers, the decision ultimately depends on intent—whether acquiring a trophy residence, a long-term investment or a fully serviced urban base within one of the world’s most resilient luxury property markets.
