The clients first thought about taking down the non-bearing wall separating the kitchen and dining room only and taking advantage of the existing openings for 2 sliding-glass doors to the 3-season room. In other words, make no significant changes to the existing structural components. In exploring this design initially, the clients quickly realized the limitations to creating the large, inclusive space they were after. We decided to take out a 15’ span of exterior brick and block wall to create a single, multi-functional space.
We were able to reuse the existing slab for the 3-season room with some underpinning for reinforcement. However, the sleepers installed to level the floor, and limitations to the roof height made it impossible to meet code requirements with traditional insulation. The floors, walls, and ceiling of the addition were insulated with spray foam. Because of the brick and block wall, it was also not possible to tie the heating and cooling of the new space into the existing HVAC system. A mini-split system heats and cools the new space
The plan involved changing the layout dramatically. Aside from the sink, all kitchen appliances were relocated, and the electric panel was replaced to power the new appliances to current code requirements. The view to the backyard was emphasized with a wall of windows. A tiled area and built-in bench allow a corner of the new space to function as a mudroom.
