A Partnership in Sustainable Living

This project marks the third collaboration between Clifton View Homes and a valued client, underscoring a long-standing relationship built on trust and shared commitment to sustainable living. Over the past 14 years, we have consistently delivered high-quality, energy-efficient homes for this family, fostering a strong partnership.

SIP Specifications:

  • Wall: 6" GPS core
  • Roof: 10" GPS core

The SIP Advantage:

The utilization of Structurally Insulated Panels (SIPs) significantly streamlined the construction process. By minimizing on-site preparation and facilitating rapid assembly, SIPs reduced labor costs and expedited the project timeline. Our team's extensive experience with SIPs ensured a seamless and efficient construction process, particularly valuable on this tight site with limited space for material staging. The "just-in-time" delivery of SIPs further optimized logistics and maximized site efficiency.

Innovative Design Solutions:

The challenging site, with limited space and the need to accommodate on-site septic and storm drainage systems, necessitated a creative approach to foundation design. By carefully designing overhangs, we maximized usable floor space while minimizing the overall footprint of the building.
