Where can I find blueprints to build a square House (ie:like Big brother)? - blueprints on how to build a sand rail

I want to build a house, the square. The backyard is surrounded a house full of absolute privacy.
I searched all over the Web in the drawings. Everything you see is the dome and the round houses.
Any help would be great.
