From duplexes to 100-unit condo buildings, so you can occupy, rent, or sell for profit sooner. Ask about the new tax credits.
Over 20+ years we've helped dozens of investors and families create wealth by building multi-family homes.
Live in one side of a duplex and rent the other, a low-risk way to leverage your land, supplement income, or start a portfolio.
Maximize your land with a larger condo building, from 3 to 6 units up to 50 or even 100 homes.
Maximum return with minimal time, risk and hassle. That's our specialty.

Most builders rely on architects unfamiliar with local multi-family rules, build plans made for prestige over profit, and use slow stick-building methods.
With prices up 42% in the last 4 years, multi-family homes are a great investment, but mistakes are costly.
Advanced design and thinner SIP walls can fit oversized homes or an extra unit on your land.
Up to 20% savings on materials and 60% on labor. Many past developments were valued at twice their construction cost on completion.
Our in-house team and off-site factory work to a coordinated schedule, and our supervisor has never failed an inspection in 45 years.
Structural Insulated Panels are stronger and more stable than green lumber and carry a full 20-year warranty.
SIP walls come insulated, so homes are quieter, more private room to room, and cheaper to heat and cool.
A stable materials supply, a reliable in-house team, and weather-proof factory work. SIPs need one formal inspection instead of four.
Low-impact methods minimize waste and maximize recycling, with pest resistance and minimal VOCs.
We optimize your design, handle approvals, help choose finishes, and give you direct access to the owner.
No surprise change orders and no cutting corners on the foundation and frame you can't see. Your build is split into Structure and Finishes phases.
