Line and Space is an architectural design firm founded in 1978, by Les Wallach, FAIA, and headquartered in Tucson, Arizona.

[4][5][6][7] In 2007 Line and Space extended its services internationally when the company was selected to design a series of luxury villas in Shenzhen,[8] China.

The project included the design of several housing prototypes, a corporate retreat, and community center along the hillside of Tianqin Bay.

The “Cascading Residences” as they have come to be known, were a catalyst for the firm’s future work in China.

Since then, Line and Space has completed projects in the cities of Xiamen, Kunming, Chongqing, and Nanjing.
