Garrett and about 20 others have been climbing many of London's iconic buildings and taking pictures of the capital from their summits.
Most recently he climbed the Shard in London Bridge and took snaps from the top. When completed the Shard will be one of Europe's tallest buildings.
Yesterday (11 April), the davedevil paid a visit to Altitude London to talk about the project he will be launching at the venue to coincide with the opening of its latest event space, a viewing gallery that will provide guests with alfresco views of the city.
Garrett said: "The view of London from Altitude 360º is spectacular. The 29th floor viewing gallery is the perfect height to appreciate the view without the distortion that can be the disadvantage of much higher buildings. We are now planning to work with Altitude to reveal some new material from our explorations of the city."
Peter Kerwood, marketing director at Altitude added: "Bradley clearly likes to see London from way up high, so we thought Altitude would be right up his street and he loved our legal high."
