apollo architects and associates builds concrete hat house

apollo architects and associates has completed a three-storey concrete home in a densely populated residential neighborhood of tokyo, japan. designed for a couple in their 50s, the client required a large enough dwelling that would allow them to live with a parent. concrete was chosen to protect against potential natural disasters, providing high resistance to fire and earthquakes. the relatively small plot size has resulted in a compact residence that maximizes its available space.

titled ‘HAT’ in response to its distinctive roof canopy, apollo architects’ design is situated at the end of a blind alley. the building comprises of three storeys, with two floors above ground and a basement. the parent’s room is located at the subterranean level, located by the entrance to the property. the couple’s sleeping quarters are found above, flanked by two offices.

the home’s interior offers abundant natural light thanks to an atrium

the uppermost level contains primary living accommodation with a kitchen, dining area, and lounge. here, wooden rafters have been used in place of concrete, creating a contrast between the two materials. although it appears closed from the outside, the home’s interior offers abundant natural light thanks to an atrium that rises through the structure. the architects sought to create a secure and protective dwelling that shields its occupants from its surroundings.
