Homes in the Earth, Design Concept Associates, 1980 House Plans Book

This 1980 volume presents forty design concepts for earth-sheltered houses, each illustrated with perspective drawings and detailed floor plans.

The book explains the benefits of earth-integrated construction, like natural insulation, reduced energy consumption, and harmony with the landscape, and shows a wide range of building types from single-family homes and hillside structures to condominiums and retreat cabins.

Introductory chapters address site selection, energy considerations, structural approaches, and financing, followed by the full collection of design layouts.

The cover shows noticeable wear, surface marks, and light staining, but the interior pages are clean and legible. A useful reference for architectural historians, designers, and readers interested in 1970s–80s alternative housing and sustainable building practices.
