Moscow-based international architecture practice Arch(e)type has presented 101M, a conceptual 250-metre tower with a vertical deep-water pool at its centre, at the A-Fest architecture festival.
The project was unveiled as a 3D-printed stainless-steel model, its pool shaft illuminated from within, at the Moscow Museum of Modern Art. It was developed together with world champion freediver Alexey Molchanov and Molchanovs, the international freediving equipment and education company he co-founded.
The tower is organised around a 101-metre column of water, a depth chosen to match the record set by Molchanov's mother, Natalia Molchanova, the first woman to descend beyond 100 metres on a single breath.
The deepest pool currently in existence, Deep Dive Dubai, reaches 60 metres below ground. In 101M a taller column rises above ground through the building itself.
The tower's form draws on the International Space Station, with modules for a freediving centre, research laboratory, offices and apartments docked to the central volume.
"Contemporary architecture is used to growing upward, and skyscrapers have long been the conventional symbol of ambition," said Daria Belyakova, founder of Arch(e)type. "101M proposes the opposite vector: depth. Here, architecture turns inward, toward the place where a person is left alone with themselves, with the pressure of the water and with silence."
Inside, the water column would allow freedivers to train at record depths year-round, independent of season and open-water conditions, and would simulate neutral buoyancy close to weightlessness. The building would house a hydro-lab for cosmonaut training that is open to the public.
The project is designed as a closed engineering system. Rainwater, meltwater and greywater from the residential floors would be filtered and returned into circulation to top up the pool, with solar panels integrated into the facade and wind turbines on the roof. One floor is conceived as an autonomous laboratory for life-support technologies for settings without external infrastructure, from Arctic stations to remote settlements.
