Category-5 is a comprehensive system for homebuilding based on a common sense approach to 21st century storms, floods and fires.

Because the system began with feature-by-feature responses to site conditions, each part represents a field-tested solution to a practical challenge. We combine these proven techniques into a 360-degree specification for security.

Our approach is different from “thinking-as-usual” about buildings because it brings strategies for climate defense together with common, well-known technologies. Familiar methods mean that contractors are easier to find, work is more timely, and costs can be controlled. Harnessed to our focus on severe weather, they produce structures that are much stronger, more durable and more survivable 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.
