Rooftop swimming pool in Bangkok by Thai landscape architects The swimming pool is positioned over the podium of a 42-storey residential complex close to the city’s main station. Both residents and passing travellers look down on the pool from above, so T.R.O.P. added a canopy of concrete frames that appear from above to slice the water up into different sections. The outline of the pool is made up of straight lines with curved edges. The team avoided perpendicular lines where possible and arranged wooden decks and planting areas around the perimeter.
