LXA has inserted a 2,000sq ft (186sq m) indoor/outdoor boxing gym into a mixed-use building in London for use by local residents and office workers.

The Secret Boxing Gym is located in a former ground floor office space that had full-height glazing on two sides. By replacing this with fold back, full height doors, LXA added a distinguishing feature to an otherwise compact gym.

The glazing makes for an airy, naturally bright studio, and maximises views of the River Thames, St Paul's Cathedral and London Bridge.

In addition to a ring and equipment for boxing training, there are facilities for HIIT, cardio work and yoga. There is also a café.

Walls and ceilings are stripped back and punch bags hang from steel frames. Simple metal caging and piping is used for some fixtures, while red and white strip lighting matches the colours of the ring ropes.

Dave Rooney, creative director of LXA, told CLAD: "In just two months, we transformed a shell and core site into a remarkable space – one that shows that real estate can flex."

LXA has previously worked on projects including the WE11 Gym Studio in London, the Crowne Plaza hotel in Edinburgh and the Wagamama chain of restaurants.

The project took two months to complete.
