Since the improvement called for a bedroom/office, the addition of a secondary means of egress leading directly from that room was necessary.
Next, careful planning for the new bathroom was necessary since concrete slab would have to be removed to accommodate new drains lines and a sewage ejector pit as well as tying all this new plumbing into the existing sanitary stack leading out to the sewer.
In order to make the basement as energy efficient as feasibly possible, inch and a half thick, foil-faced polyisocyanurate insulation boards were installed full height, including between all the floor joists along the entire perimeter of the basement. All joints were either taped or sealed. From there, the perimeter wall framing was held a half inch from the insulation to minimize any thermal bridging. The backs of all electrical junction boxes were covered with reflective foil tape and all the wall plates used were gasketed.
Since carpet was desired in some of the areas, a subfloor was necessary to avoid the musty smell that carpet often takes on when installed directly on top of concrete, especially in a basement. In lieu of the more traditional system of pressure-treated wood sleepers and plywood, a low-profile, snap-together system of plastic 24”x24” squares was utilized. This system cut down on installation time as well as the overall height of the assembly, making transitions between flooring materials almost negligible.
