Starting with the roof
structure and brick floor of an existing screened porch, this became a
conditioned family room/sun space, whose major function was to house the
owner’s grand piano and collection of books. Proper climate conditioning
was required to protect the Steinway piano. This was difficult since
there was little space for HVAC equipment and few walls or chases to
bring the heating supply down to the floor of the 14’ high room. To
accomplish this, a fan coil unit was installed in the existing ceiling
plenum. Access is provide through a removable exterior gable vent.
Supply lines were fitted down the only two exterior wall sections, which
were designed as 8" thick. Structural concerns were addressed by
diaphragm walls, special fastening systems, and collar ties designed to
fit seamlessly between stacked window sections.
