20×40 House Plans East Facing
House plan of 6.5x12m on one level, with an open garage. Low cost materials, such as reinforced concrete, block walls and smooth cement, are used to create a beautiful and elegant modern facade.
It is a 60 square meter house (650 sq ft), with an open garage, 1 bedroom and a bathroom.

The play of flat roofs at different heights enhances the modern design of the front elevation. The aluminum and floor-to-ceiling glass window is combined with the double-leaf entrance door (one fixed leaf).
The façade is just over 6.5 meters wide with 12 meters floor long. The colors white and beige, in combination with the green vegetations and the outdoor gardening, complete its modern exterior design.

The house can be built on land with a dividing wall, that is, one of the side walls is blind (without openings).

Integrated into a single space are the living room, dining room and kitchen. From the kitchen it would be possible to go out to a rear patio. The only bedroom has a usable area of 13.3 m².


To get in the house, with less direct views towards the dining room and kitchen, the access door can be placed on the wall that separates the open garage from the living room. Thus, the first sight will only be towards the living room.
