The owners desired all vaulted areas with trusses with open spaces and visible timbers. Energy efficiency was a big factor. Owner is able to heat the entire home with the two gas fireplaces tested down to 0 degrees outside temperature. Energy costs are less than half of his previous home -- 1/4 mile away and 1/3 the size.

  • Wood with concrete gypcrete floor, finished.  No carpets in entire home to help with asthma problems. 
  • Saved some of the beams from an existing hotel (over 100 years old) and made them into mantels and decorative components in the home. 
  • The decks around the home are made of concrete to eliminate the chance of deterioration and safety. 
  • The roof is all decorative steel shingles to have a build-in airflow under them to dry the roof deck and carry a 50-year life. 

House was designed in a shape to not remove any of the 100+-year-old oak trees on the site and still have a view of the lake. T

he project came in on budget with the estimates BEFORE SIPs were estimated - so the energy savings offset any cost increase on the project as a whole. It was the contractor's first SIPs project and the homeowners were so impressed that he has hired a crew of in-house builders to go after more projects utilizing SIPs.
