This is a mass-produced type ready-built house often developed on a large scale, and as such, has the advantage of producing entire housing of rows. In many cases, as the appearance is coordinated at the designation of the owner, rows of houses that do not necessity match esthetically are created. In order to overcome this 4 units are created together at Hozumidai to appear as one building by design, carrying out a strong message to the town. Price competitiveness was maintained by cost effective production of the facade design.
