Custom Home Renovations

70’s Gambrel Update

This renovation of a 1970’s colonial called for a reconfiguration of the kitchen and family room to create a modern open floor plan with much improved access to the rear deck and screened porch. The existing insulation was very poor with lots of envelope air leakage, so the project included a dramatic upgrade to the thermal envelope and a ground-source heat pump system. The first heating season saw a total heating and hot water expense of $800, according to the owners.  One of the owners says that his kids no longer want to go on sleepovers because other Ridgefield homes are so much less comfortable than theirs!

Green Building Approaches

  • After the siding was stripped, 2×3 studs were attached to the exterior face of the walls with spacers to hold them 1” off the sheathing. Then 3” of closed-cell spray foam was applied to the walls, creating an air-tight, thermal bridge-free wall system.
