Castle Rock Design and Development

A Fine Balance of Engineering and Design for a Higher Standard of Living

Castle Rock Design and Development, inc. is an innovative design and construction company that specializes in unconventional concrete buildings and homes. This unconventional building type is earthquake-proof, fire-proof, and hurricane-proof. The structure is based on shotcrete and steel rebar (instead of wood) and there are no wall cavities. Termites have no wood to chew on and the lack of wall cavities simplifies long term maintenance. The polyurethane foam insulation on the outside keep the structure temperate, making it cool in summer and warm in winter.
