Located in a residential area in Hyogo Prefecture, Japan, the house was designed by Tato Architects for a family with two children.

To achieve this, the architect designed two of the rooftop sheds like greenhouses with translucent polycarbonate walls that let light through into the study room and bathroom contained inside, as well as down to the ground floor spaces below.

A layer of translucent insulation prevents the bathroom walls becoming too transparent. "There is no problem because they are not clear enough to expose more than the silhouettes," explained Shimada.

"The residents requested that, as the area has short hours of sunlight in winter, they'd like to bring in as much light as possible."
