Project Description:
Our client was looking to re-utilize their existing two-car garage as an additional living space and apartment for their mother and guests as well as creating an addition to house a family mudroom and dining area and upgrading their kitchen. The existing garage slab was excavated and insulated. The wall system received continuous insulation with new blown-in cellulose and the roof was reframed with 2x12 KD Spruce with a dense-packed cellulose cavity and a continuous interior air and insulation barrier. A new foundation and slab was poured for the connecting addition and the kitchen was opened and to the space with continuous structural carrying beams to create full connectivity.

Highlights from the Judges:
