London’s skyline is set to gain a truly unusual feature. A rooftop swimming pool is planned for the BT Tower, a 177-metre landmark in Fitzrovia. The idea of swimming that high above the West End feels both surreal and inviting. The tower, once a hub for microwave communications, is being reimagined as a luxury hotel by its new owner, MCR Hotels. This transformation promises to open up a part of London that has been closed to the public for decades.
The Vision for a 177-Metre Rooftop Pool
The planned bt tower rooftop pool would sit atop one of London’s most recognisable structures. It is not just a place for a few lengths. It represents a bold attempt to blend heritage with modern hospitality. MCR Hotels, which bought the tower from BT Group in 2024 for £275 million, has revealed these ambitions through public consultation events. The developer wants to preserve the Grade II listed building while adding amenities that draw visitors upward.
A swimming pool at this height presents obvious engineering puzzles. The tower is slender. Its original design supported heavy telecoms equipment, not the weight of water and guests. Structural reinforcements will be necessary. The developers must also work within strict rules that protect listed buildings. Every change to the fabric of the tower needs approval from heritage authorities. This makes the bt tower rooftop pool a project of careful balance between old and new.
How the Pool Fits into the Wider Hotel Plan
The pool is just one part of a larger proposal. MCR plans to turn the entire tower into a hotel. Guests would stay in rooms wrapped around the cylindrical core. The top floors, including the 34th floor where a revolving restaurant once turned, will likely become premium spaces. The rooftop itself, where the pool will sit, offers views that stretch across the capital. On a clear day, you might see from the Olympic Park to Windsor Castle.
Public access is a key theme of the plans. For the first time in nearly fifty years, people who are not hotel guests might reach the top of the tower. The proposals include a publicly accessible square at ground level, along with shops and restaurants. This opens up a site that has been a silent giant in the neighbourhood for decades. The bt tower rooftop pool becomes a symbol of that new openness.
Public Consultation Events in May 2025
MCR has scheduled three public consultation events. They will take place on May 11, 12, and 16, 2025. These sessions give local residents, history enthusiasts, and curious Londoners a chance to view the emerging proposals. Attendees can meet the project team and share feedback on the plans. This is a critical step before formal planning applications are submitted.
For anyone living in Fitzrovia or nearby Bloomsbury, these events matter. The tower’s conversion will change the character of the area. More foot traffic, new retail spaces, and a hotel entrance will alter the daily rhythm of the streets. The consultation offers a direct line to the developers. You can ask about noise, construction timelines, and how the bt tower rooftop pool will be managed. It is a rare opportunity to shape a landmark’s future.
How to Attend and Prepare
Details of the venues and times for the May events are expected to be published on the MCR Hotels website closer to the date. Typically, such consultations are held in a local hall or community space. You can drop in during the advertised hours, view display boards, and speak to architects and planners. It helps to come with specific questions. Ask about the pool’s dimensions, heating systems, and whether it will be open year-round. The more detail you request, the clearer the picture becomes.
If you cannot attend in person, there may be an online feedback form. Many developers now offer digital alternatives. Keep an eye on local news outlets and the Fitzrovia neighbourhood forum for updates. Your voice matters, especially on a project as visible as this one.
Preserving History While Adding a Modern Pool
The BT Tower is Grade II listed. This status protects its historic character. The tower was originally called the Post Office Tower when it opened in 1964. Its purpose was to support microwave antennas that beamed telephone signals across the country. That telecoms heritage is written into the building’s bones. The cylindrical shape, the external louvres, and the rotating restaurant mechanism are all part of its story.
Adding a bt tower rooftop pool to a listed structure is not straightforward. Any alteration must respect the original design. The pool cannot simply be plonked on top. It must be integrated in a way that feels intended, not bolted on. Architects might recess the pool into the roof structure or use materials that echo the tower’s existing cladding. The goal is to make the addition look as though it could have been part of the original vision.
Lessons from Other High-Rise Pools in London
London already has several sky-high swimming venues. The Sky Pool at Embassy Gardens in Nine Elms hangs ten storeys up between two apartment blocks. It is made of transparent acrylic, giving swimmers a view straight down. The infinity pool at the Shangri-La Hotel in the Shard sits on the 52nd floor. It offers a dramatic panorama of the city. The Berkeley Hotel in Knightsbridge has a rooftop pool overlooking Hyde Park. Each of these projects faced similar challenges: weight, wind, privacy, and safety.
The bt tower rooftop pool can learn from these examples. The Sky Pool, for instance, required extensive structural reinforcement and specialist glazing. The Shard’s pool needed careful climate control to prevent fogging at altitude. The Berkeley’s pool is shielded by a glass screen that blocks strong winds. MCR’s design team will likely draw on these precedents. The result could be a pool that feels both thrilling and secure.
The Revolving Restaurant Legacy
The 34th floor of the BT Tower once housed a revolving restaurant. It completed a full rotation every 22 minutes. Diners could enjoy a meal while the London skyline slowly paraded past their window. It was a marvel of 1960s design and a favourite spot for special occasions. The restaurant closed in 1980, and the floor has been used for telecoms equipment ever since.
Many people wonder whether the revolving restaurant will be revived. The current plans focus on the rooftop pool rather than a rotating dining room. However, the hotel might incorporate a restaurant or bar on a high floor. Whether it revolves remains to be seen. The mechanism that once turned the restaurant is still there, buried under later additions. Restoring it would be a complex engineering task. For now, the bt tower rooftop pool takes centre stage in the public imagination.
What the Pool Means for Tourists and Locals
A tourist planning a trip to London in 2026 might dream of swimming above the city. The reality is that the pool will likely be reserved for hotel guests. That is the model used by the Shangri-La and the Berkeley. Non-guests cannot simply buy a day pass to swim at that height. Security and capacity constraints make exclusive access practical. However, the public will have other ways to enjoy the tower. The ground-level square, shops, and restaurants will be open to everyone. There may also be a viewing gallery or bar on an upper floor.
For a local resident in Fitzrovia, the pool is a symbol of change. The neighbourhood has grown more residential and upscale over the years. A luxury hotel with a rooftop pool will attract a different crowd. Some residents welcome the investment and the opening of a long-closed landmark. Others worry about noise, traffic, and the loss of the tower’s quiet mystique. The public consultation is the place to air these concerns.

Timeline for the BT Tower Hotel Opening
The conversion will not happen overnight. BT Group sold the tower with a six-year timeline for removing its telecoms equipment. That process runs until 2030. During that time, MCR can begin preparatory work on the lower floors and the podium buildings. The rooftop pool and hotel rooms will likely come later in the project. A realistic opening date might be 2028 or 2029 for the first phase, with the full hotel and pool operational by the early 2030s.
This slow pace is typical for projects involving listed buildings. Every structural change requires approvals. The removal of telecoms gear must be done carefully to avoid disrupting services. The developers have time to refine their plans and respond to feedback. The bt tower rooftop pool is a long-term ambition, not an immediate reality.
What Happens to the Telecoms Equipment
BT will gradually strip out the antennas, dishes, and cables that have filled the tower for sixty years. Much of this equipment is obsolete, replaced by fibre optic networks and modern wireless systems. The removal process is itself a logistical challenge. The tower was built to house heavy gear, and taking it out requires careful planning. Some components may be preserved for museum displays. The tower’s original purpose as a microwave relay station will become a historical footnote.
Engineering Challenges of a Rooftop Pool
Building a pool 177 metres up is not like installing one in a back garden. The structural load is immense. Water weighs roughly one tonne per cubic metre. A medium-sized hotel pool could hold 50,000 litres or more. That adds 50 tonnes of weight, plus the pool structure, filtration systems, and people. The tower’s frame must be reinforced to carry this load safely.
Wind is another factor. At that height, gusts are stronger and more frequent. Water in an open pool can slosh dangerously. The developers might enclose the pool with glass screens or design a sheltered area that still feels open. Heating the water at altitude also requires efficient systems. The pool will need to be comfortable even on a cool London day. These are solvable problems, but they add cost and complexity to the bt tower rooftop pool project.
Safety and Security Considerations
A pool at this height raises obvious safety questions. Barriers must prevent falls. The pool area will likely be accessible only to guests with key cards. Lifeguards or trained staff will be on duty during opening hours. The developers will also need to plan for emergencies. Evacuating a high floor of a slender tower is not simple. Fire safety, water quality, and structural monitoring will all be part of the design.
The BT Tower in Popular Culture
The tower has a quirky place in British pop culture. It appeared in a 1970s episode of the comedy series The Goodies. In that episode, a giant kitten climbs the tower, causing chaos. The image of the tower with a huge feline clinging to it is fondly remembered. The new hotel and pool will add another layer to the tower’s story. Future visitors might snap selfies on the same spot where a fictional kitten once perched.
This cultural resonance matters. It makes the bt tower rooftop pool more than just a hotel amenity. It becomes part of London’s ongoing narrative. People who have never been inside the tower still feel connected to it. The conversion respects that connection by keeping the tower’s silhouette intact while adding a new chapter.
What the Future Holds for Fitzrovia
The area around the BT Tower is already changing. Fitzrovia has transformed from a mix of light industry and media offices into a sought-after residential and commercial district. The hotel and its public square will accelerate that shift. New shops and restaurants at ground level will draw people who currently walk past the tower without a second glance. The bt tower rooftop pool will become a destination, not just a landmark.
For a local business owner, this could mean more foot traffic and higher rents. For a resident, it might mean more noise during construction but a more vibrant neighbourhood afterwards. The public consultation is the moment to weigh these trade-offs. The developers have promised to listen. The shape of the final project will reflect that dialogue.
Comparing the BT Tower to Other Iconic Conversions
London has seen several landmark buildings turned into hotels. The Gherkin, for instance, has a restaurant and bar at the top but no hotel rooms. The Walkie Talkie building has a sky garden that is free to visit. The Shard combines a hotel, restaurants, and a viewing platform. The BT Tower conversion follows this trend of opening up iconic structures. What makes it unique is the addition of a swimming pool. No other listed tower in London offers that combination of height and water.
