The main objective for the second and third floors was to install air conditioning in all rooms while making a few cosmetic improvements along the way. Although extensive work was required to weave central air conditioning through the house, the results are deliberately understated.

In the third floor hallway seen here, it was necessary to lower the ceiling to conceal the existing sprinkler piping and new ductwork. To allow for the hallway ceiling height to be reduced, the irregular door heights had to first be unified, and some of the door frames received new casings that matched the existing trims. Last of all, a small but bold crown moulding was installed to unify the space and visually "erase" our intervention.
