this 1980’s ‘passive solar’ home was very ill-lit with an ad-hoc space arrangement. by adding a small family room, taking down some walls, adding floors and removing ceilings we created a bright, functioning home. we created a wall detail with our Passive House consultant that allowed for an extremely well-insulated wall with very few thermal breaks, which created a more comfortable internal climate. the addition has a green roof! and a new geothermal system, all new PEX plumbing throughout, a sleek pellet stove insert, and many other great ‘green’ features.
