Welcome to the Public Consultation website on proposals to regenerate The Lowndes Hotel, 21 Lowndes Street.
The Lowndes Hotel has occupied this corner for 60 years. The 1960s building that houses it no longer meets the expectations of the area or the standards of the contemporary luxury hospitality market.
Following three years of pre-application discussions with Westminster City Council and a public consultation in July 2025, we are bringing forward revised proposals: 33 hotel rooms, a food and beverage offer, and a private members club, with the massing reduced by a storey compared to the scheme shown in 2025.
We are keen to hear the views of local residents and businesses as we develop our proposals.
Read on to find out how you can get involved in our latest public consultation.
The Lowndes Hotel is managed by The Carlton Tower, a trust that manages a portfolio of real estate assets in the heart of Knightsbridge. We have engaged with a series of London based professional consultants, who have extensive knowledge of designing and delivering buildings in the borough of Westminster and working on hotel projects.

The existing building has reached the end of its useful life. Key issues include:








In line with Westminster City Council and Greater London Authority policy, all options for the full or partial retention of the existing building structure have been explored before bringing forward a demolition proposal. The existing structure cannot viably accommodate the necessary upgrades.
67% of respondents to our 2025 public consultation strongly agreed that the hotel needs upgrading. 65% strongly supported replacing the building.
The current building has a low floor to ceiling height and a narrow building footprint and structural grid, making the room sizes smaller than most five-star offerings.
The existing building is compromised on the ground floor, both in terms of a clear area and height, resulting in a restricted offering for guests and the local community.
The revised proposals replace the existing 1960s building with a Ground plus seven storey development comprising 33 hotel rooms, food and beverage, and a private members club. The massing has been reduced by a storey compared to the version shown at our 2025 consultation events.
Designed by Squire + Partners, the architecture takes inspiration from the neighbouring Belgravia area. Materials and proportions have been carefully chosen to harmonise with the existing neoclassical buildings and respond to the Belgravia Neighbourhood Plan.
The proposals include:
Construction will be managed under a formal Construction Management Plan agreed as part of the planning approval, confirming working hours, lorry routes, and a named resident liaison for the duration of the build.
The scheme is owned by Carlton Tower Limited and will operate as a five-star hotel with a private members club.
The proposals will replace the dated 1960s building with high-quality architecture which enhances the surrounding context.

In addition to the hotel’s design improvements, the project will enhance the public realm, activating shared spaces and delivering significant upgrades to the Halkin Arcade. The relationship with the existing courtyard will also be improved, creating a more open and inviting environment.
The project will also deliver significant upgrades to the hotel’s environmental performance, ensuring it complies with the highest standards in thermal and carbon efficiency.
By ensuring the hotel remains a competitive luxury destination, our renewed investment in The Lowndes Hotel will deliver wide-ranging economic benefits for Knightsbridge and Belgravia, supporting the visitor economy in this unique destination.
The upgrades will support increased spend and footfall within the locality, while the additional facilities will create additional jobs across a variety of sectors to support a diverse range of local employment opportunities.
The proposals include a significant investment in public realm. The Halkin Arcade, which runs through the ground floor of the site, will be upgraded and re-activated for public use. A ground floor restaurant will be open to Lowndes Square, creating a new active frontage on the street.
The Halkin Arcade upgrade was the most supported part of our 2025 consultation. These improvements are being brought forward in direct response to that feedback.
• Halkin Arcade upgraded and publicly accessible
• Ground floor restaurant open to the street
• Activated frontage replacing the closed, inactive ground floor of the existing building
• Improved streetscape at the corner of Lowndes Square and Halkin Street
• Greening of the space with connection to the rear courtyard
74% of respondents to our 2025 public consultation strongly supported improvements to the Halkin Arcade.


Your feedback is important to us as we develop our proposals. We would be grateful if you could complete the survey below. We will review all feedback received before submitting a planning application to Westminster City Council later this year.
