the challenge of the project was to follow the local construction requirements of the area; each building’s roof must be sloped and covered 50% in grey or terracotta-colored tiles. vo trong nghia and masaaki iwamoto responded to this by dividing the roof into parallel bands – each planted with greenery – and then tiled in an alternating sequence. coupled with its easy accessibility, the roof has become a pocket park open the inhabitant’s neighbors, while being visually connected to the surrounding, mountainous landscape.

trees, flowers and plants fill each horizontal row on the roof

below, the interior floorplan follows the banded characteristic of the roof. voids and interior courtyards provide natural light and encourage air flow. the living, dining and bed rooms are placed under the tiled roof and the service spaces, including the bathrooms, storage and circulation spaces, are located under the green roof.
