Made-to-order condominiums are gaining popularity in Japan as people seek more distinct housing.

Potential owners form cooperatives and engage firms to deal with getting land, designs and construction. They decide on their floor space, interior fixtures and decor. As a result, the concept is known as cooperative housing.

The Japan Cooperative Housing Association, a nonprofit organization for promoting such dwellings, says there are more than a dozen coordinating companies to handle the needs of people interested in such homes.
