Category-5 is a homebuilding system made for modern temperatures, floods, storms and fires, and for resilience in the face of climate change. Our durable, survivable buildings bring together strong and efficient materials to deliver the security, comfort and beauty that homeowners deserve.

The system is based on techniques we’ve developed over decades to tackle the hazards facing our clients. These have included, for example, designs for fire resistive walls, and roofs that harness cooling breezes. Combined, they offer a comprehensive strategy for 21st century shelter.

Traditionally, “thinking-as-usual” about adapting homes to bad weather has favored minor technical fixes, or optimistic “magic bullets” — as if there's a quick solution to be found. But piecemeal changes and utopian dreams haven't delivered true resilience.

Instead, creating defensible homes and communities at the speed of climate change requires a new take on some of our best-known technologies. Using them in reimagined assemblies (for walls, roofs and other elements) can quicken the adoption of new solutions as well as improve performance. For example, we’ve learned how old, easily-understood techniques can be combined in unconventional ways to resist fire. Familiar methods mean contractors are easy to find, work can be timely, and costs better controlled. The new assemblies themselves can deliver remarkable breakthroughs in efficiency and durability.

There are no guarantees in a contest with nature, but integrated with their contexts and focused on combating severe weather, our buildings can assure greater comfort and security than any alternative.

Category-5 Partners is pleased to offer planning and builder support for construction of this unique system, including step-by-step guidance for owners, engineers and qualified contractors, and services related to specifying and purchasing its elements.
