Category-5 is a system for homebuilding dedicated to resisting 21st century storms, floods and fires, and to resilience in the face of climate change.

Our feature-by-feature answers to the practical challenges confronting our clients have resulted in field-tested strategies for surviving and thriving under modern conditions. In combination, these proven techniques can deliver 360-degree security.

We reject “thinking-as-usual” about climate safety because piecemeal and “magic bullet” solutions aren't solutions at all. True resilience requires bringing together the most effective and most available technologies and applying them ecologically. Familiar methods mean contractors are easy to find, work can be timely, and costs better controlled. Integrated with their natural contexts and focused on combating severe weather, our buildings can assure greater efficiency and survivability than any alternative.

Category-5 is pleased to offer training and step-by-step guidance to qualified contractors and owners, in addition to custom building services.
