earthsupported

Earthsupported is a term used in architecture and civil engineering to describe designs where the surrounding earth provides significant structural support or enclosure. In practice, earth-supported approaches use soils or earth berms to contribute bearing capacity, lateral restraint, or thermal mass, reducing the reliance on above-ground framing. The concept covers configurations such as bermed or partially buried buildings, rammed earth or adobe walls that transfer loads to the soil, and structures integrated with sloped terrain.

Design considerations include site geology, soil bearing capacity, drainage, moisture control, and frost action. Architects and engineers must coordinate foundations, wall systems, waterproofing, and insulation to prevent moisture intrusion and thermal bridging. The interaction between soil movement and structural response is a central concern, requiring careful detailing of backfill, compaction, and drainage layers.

Advantages of earthsupported designs can include improved energy efficiency through thermal mass, aesthetic integration with the landscape, and reduced above-ground mass. Limitations include moisture management risks, potential differential settlement, construction complexity, and maintenance requirements in certain climates.

Earthsupported is not a universally standardized term, but it appears in design guidelines and descriptive literature to distinguish structures that rely on earth for part of their load-bearing or enclosure strategy. Related concepts include earth sheltering, bermed architecture, rammed earth, and earth-integrated construction.
