chicken coup - Kathy Siegel's Los Angeles coop was designed around a beautiful salvaged window that her husband found. Using Google Sketch-Up, Siegel designed the house to incorporate air, light and plenty of protection. The coop has a series of screened areas under the rafters, which allows for clean air circulation. The structure is nestled against a retaining wall, so Siegel had to design all the entries and exits through one set of side doors.
