This Whimsical Home in Japan Encourages Play and Exploration

Exposed wooden trusses and polycarbonate walls are just some of the features of this playful, Kobe residence.

In Kobe, Japan, looking out towards Mount Rokko, the playfully designed Hat House by local studio Fumiaso Architect & Associates features diagonal internal walls that capture sunlight entering from the south. Exposed timber trusses, arched thresholds, an imaginative interior alley and courtyard, greenery, and tansu staircases work together to create a dwelling that's cheerful and full of whimsy.

The placement of the angled walls results in an interesting juxtaposition of interior spaces in the approximately 878-square-foot home, including triangular and parallelogram-shaped rooms.

Polycarbonate sheets separate the functional zones while still allowing light to pass through, so all areas of the home are well illuminated.
