The company
Building houses in Sakai
since 1972.
We have been building houses in Sakai since 1972. Design and construction are connected within one company, so the same information is carried through consultations, drawings, and the building site.

What we do
New houses (design and construction), renovation, remodelling, shop interiors
Where we work
We work mainly in Sakai City, across southern Osaka and Osaka Prefecture. About an hour by car from our office is one rough guide; for areas beyond that we confirm the use, the scale and our construction capacity, and answer case by case.
How we work
Design and construction, in one company
We hold the first-class architect office registration ourselves. The intent of the design goes straight to the site, so nothing is diluted in the passing on.
Not only houses
As well as new detached houses we do renovation, remodelling, apartment interiors and shops. Working on buildings with different uses gives us more ways to solve a house.
