Single-family home, with mother-in-law suite on the main accessible level. SIP construction is one of the primary keys to our company's success in designing and building Zero-Energy Homes.

We are sought after for our skill and experience in using SIPs to achieve outstanding energy efficiency. SIPS are the key to tight, energy efficient construction, without the thermal bridging, and on-site labor issues required by conventional stick-framed construction. SIPS also allow our entire roof to be installed and dried in within a single day of work. This allows sub-contractors to be working inside the home much sooner, advancing the schedule by weeks.  

The large open rooms on both the main floor and second floor required lots of large beams. The tall ceilings and craftsman style allowed some of those beams to be partially exposed, while still leaving the house with a very open and airy feel. This SIPs roof was engineered using I-joist splines to increase the spans, keeping the attic area open and usable as a hobby room. 

The view from the attic over the town and yacht basin is spectacular. This project is a great example of how a very traditional craftsman-style home can be constructed using the latest materials and methods, at the same time achieving futuristic energy efficiencies. The HERS rating of -19 is the lowest we have achieved to date.
