Where can one build underground?

From a Colorado Rockies peak 9,500' above sea-level to a Long Island swamp, experience in UNDERGROUND HOME construction shows one can build anywhere!

The construction techniques developed by the Underground World Home Corporation make it possible to build a home in any substratum, be it granite or bog land. The secret lies in the oblong, concrete-steel shell that not only seals out all moisture but is engineered to protect the home from earthquakes and other natural hazards for several lifetimes.

Here a cross-section of the shell encasing the UNDERGROUND HOME at the World's Fair reveals the unique construction features of this revolutionary concept of residential design.

Protected against accidental puncture by Celotex panels, the three-layered membrane forms a water-tight seal around the entire shell. Inside the membrane, the concrete-steel shell varies in thickness from 20" on the floor to between 10" and 13" for the walls and ceiling. The 18" girders, forming the interior frame, support a dead load of over 2 million pounds of soil, permitting the homeowner to build surface structures such as garages and sun-rooms in addition to a small park or garden.

All connections through the shell and its protective membrane, including air-vents, utility lines and sewage pipes, are water sealed and enter at a central point assuring ready accessibility.

This unique, sealed shell can enclose a world of any dimension or content. The thousands of tons of natural soil or rock insulation protecting it from surface sound and the attack of the elements make it an ideal container for any structure in which people work, live, play or study.

Examples of current underground construction

"I'm not talking castles in the sky. These are strictly below the turf."
Alex Bilanow Washington Daily News October 2, 1964

. Underground School, Lake Worth, Texas: To accommodate nine grades, 1,300 students.
. Underground Motels and Restaurants near airports and large transportation terminals everywhere.

Today, from a hospital in Stockholm, Sweden, to a shopping center in Osaka, Japan, the development of underground structures is expanding along with man's need for an environment he can control.

Proposed underground construction, serving industry and commerce: (1) Underground Shopping Center, (2) Underground Motel, (3) Underground Restaurant and Night Club.

Design and construction techniques and the actual services of 18 different engineering specialists go into the planning of construction by the Underground World Home Corporation.

At present, UNDERGROUND HOMES completed or in development in various parts of the United States are all custom installations. Currently, construction costs for these Homes in the United States vary between $12 and $24 per square foot, depending on the expense of local labor and materials. The development of prefabricated shells for non-custom installations is expected to radically lower the over­all construction costs.
