In 1927, Wright built a residence for himself, made of two units – one for living and one for work. The 2,413 square feet (224.17 square meter) of living space has an upstairs residence with a living room, a fireplace and wooden floors. Interlocking blocks with a stylized Joshua tree design overlay some of the windows. The Great Depression stalled Wright's firm as he was reaching his artistic and professional peak. As for many architects, remodellings, rather than total designs, were the scope of 1930s work. His post-war designs became more expressionistic and less aligned to previous modernist architectural themes. He also promoted the word Usonia.
