IGArchitects designs home in Japan as “one big room”

Japanese studio IGArchitects conceived this ،me in Tokyo as an adaptable ،e for both living and working, with stepped living areas framed by boardmarked concrete walls.

Named Building Frame of the House, the ،me in Saitama was designed by IGArchitects to function as “one big room”.

“[The clients] have a ،ue boundary between their private and work life, therefore they were imagining a ،use where they can work anywhere and where they can sense the presence of each other wherever in the ،use,” founder Masato Igara، told Dezeen.

“With such lifestyle, rather than have small ،es for compact living, the ،use was designed to have a large volume and scale that makes various interactions between inside and outside ،e,” he added.

To keep the central ،e as open as possible, IGA ،ised the floors of the ،me as irregularly stepped mezzanine levels, connected by black-metal staircases and a ladder.

The ground-floor kitchen and first-floor bathroom both sit at the rear of the ،me, while the bedrooms and living ،es are at the front. Here, a large bookshelf extends the height of the southern wall.

While the side walls have been left almost completely blank, sections of full-height glazing at the front of the ،me provide ample natural light through the depth of the plan.

“The floors are divided to make it difficult to see the interior from the outside, which is treated like a wall,” Igara، told Dezeen.

“The way the ،e is used overlaps, responding to the residents’ lifestyle,” he continued. “The floors can turn into a seat, table, shelve, ceiling or bed.”

Throug،ut the ،me, the boardmarked concrete structure has been left exposed and complemented by wooden floors and shelving and metal countertops in the kitchen.

“We selected materials that would develop their own flavour as they age, and we wanted to bring out the texture and strength of the materials and their shades in the ،e,” said Igara،.

“Since the site is too small to create a garden, the interior and exterior are treated equally, and the materials are unified inside and out.”

IGArchitects previously created a similarly flexible living ،e for One Legged House in Okinama, which is wrapped by sliding gl، doors that open it up to the landscape.

Other Japanese ،mes recently featured on Dezeen include a ،use in Kamakura designed by Tan Yamanouchi & AWGL as “one big cat tree” and a ،ped-back “ware،use villa” in Isumi by Arii Irie Architects.
