Project Overview
TC Legend North Bend Platinum
End Use: Residential Single-Family Home
Why SIPs?: TC Legend Homes was selected as the builder for this project. TCL coordinated all aspects of the project from design through construction and has developed consistent high-performance home systems that rely on the energy-efficient components that Premier SIPs offer.
Benefits of SIPs: Helped save time, labor, construction costs, and energy costs. Install time was days, not weeks which equates to a reduction in framing and other trade labor. The use of Premier SIPs lent to the design of this home, for 2nd floor vaulted ceilings, natural surfaces, and exposed flooring.
Innovative Design Elements: The entire project was engineered to be high-performance in a region of Washington State just outside of Seattle before the mountain passes. This climate has hot summers and cold winters and the seasonal temperature swing required careful planning to achieve such results.
