1955 House & Garden -house of ideas | architect: Palmquist & Wright

All families must cope with the fact that two generations have two different ideas about the good life. Parents are inclined to relative peace and quiet, while children are dedicated to noise. How best to satisfy these opposing points of view? The obvious solution is a house that permits plenty of freedom for both generations. This house goes a step further: it combines all of the advantages of two separate, one-story houses under one roof. It also makes the most of its site, which slopes sharply to the south. You enter the house on the upper level and you find a complete one-floor house. 

Downstairs is another floor for living: a big family room, with a cooking-barbecue area that opens to the terrace; a hobby room, one bathroom, and provision for two future bedrooms and an extra bath. Result: two-level living, 2,300 square feet of living space on each floor, opened to the sun and view by great window-walls along back of the house.
