keita nagata embeds greendo apartment building into the landscape of takamatsu, japan

in the japanese city of takamatsu, architect keita nagata has built an apartment complex into the region’s existing landscape. named ‘greendo’, each of the project’s five residences are embedded into the terrain, sandwiched between two roads in a residential and mountainous part of town. despite its relatively small scale, the complex project took two and a half years to complete.

designed by local firm keita nagata architectural element, the scheme comprises five levels, each covered with grass and natural vegetation. ‘I dreamed about bringing back the original landscape to this place,’ explains keita nagata. each dwelling has its own outdoor garden overlooking the city below. these greened terraces form the roofs of the homes below, providing good thermal insulation and a stabilized internal temperature.

the project was praised at this year’s g-mark japan GOOD DESIGN award, where it caught the eye of architect jo nagasaka. ‘usually green roofs separate actual ground soil and soil for the roof — so the natural ecosystem can not be continued,’ nagasaka told designboom. ‘however, the architect has designed a plan which has a continuation between the ground and roof to create a new ecosystem.’
