Container-Based ADU and Accessory Dwelling Unit Construction
This company specializes in building homes using repurposed shipping containers — a construction method that offers remarkable durability, resilience, and cost-effectiveness compared to traditional building approaches. As an innovative ADU builder and accessory dwelling unit builder, they leverage the inherent strength of steel containers to create comfortable, environmentally friendly living spaces that can serve as backyard cottages, in-law suites, and more.
Shipping containers are engineered to endure extreme internal and external loads under the harshest conditions. Their steel structure is stronger than a conventional wood frame and is naturally resistant to fire, mold, and insects — making them an outstanding foundation for residential construction.
Key Structural and Safety Features
One of the most compelling aspects of container-built homes is their exceptional resistance to natural disasters and severe weather conditions. These structures offer:
- Hurricane resistance — the solid steel frame, anchored with concrete foundations, can withstand winds of up to 170 mph.
- Earthquake resistance — designed to handle forces from all directions, making structural collapse highly unlikely.
- Tornado resistance — when properly anchored and reinforced with a solid foundation, container homes respond well to tornado conditions.
- Severe weather resilience — built to survive long ocean voyages, these homes hold up against inclement weather anywhere on the planet.
- IBC compliance — all design and construction follows the guidelines of the US Residential Building Code.
Beyond safety, these homes are designed for comfort. Container widths can be expanded from the standard 8 feet to 11 feet, accommodating living spaces comparable to those found in traditional homes. Interior wood framing provides insulation and a finish that mirrors conventional residential construction.
Additional practical features include adaptability to uneven terrain through independently adjustable support stilts, easy transportation as fully assembled factory-built units, and simplified installation that avoids costly perimeter foundation walls.
Available Models and the Building Process
Containers are available in two primary sizes — 20-foot and 40-foot — and can be combined in numerous configurations to produce a wide variety of floor plans. Some of their notable models include:
- House Sparrow 208 — a compact 208 sq ft unit built with one 20 ft High Cube container and a bump-out.
- House Owl 640 — one of their most popular models, built with two 40 ft High Cube containers, available in two- and three-bedroom versions.
- House Eagle 960 — a larger configuration for those needing more space.
- House Albatross 1760 — a spacious unit combining four 40 ft and four 20 ft High Cube containers with additional stick-built space.
Their process is structured and transparent, moving through clearly defined phases:
- Design — client requirements are discussed, a standard model is configured or a custom concept is developed, and an estimated cost is provided.
- Planning — a project timeline is established, and materials and resources are secured.
- Construction — metal work, framing, plumbing, electrical, and finishing details are completed in sequence.
- Quality Control — all systems are verified and the unit is prepared for local government inspections.
- Delivery — the completed home is transported to the client's designated site.
- Installation — modules are connected and interiors are finished, with local contractors engaged for utility hookups.
