ofThe Wissioming Residence, located in Glen Echo, Maryland, is sited on a heavily wooded lot overlooking the Potomac River. The new house occupies a pre-existing house’s footprint in an effort to minimally disturb the site, removing no mature hardwoods in the process. A new swimming pool is suspended twenty feet above grade to further reduce the impact to the steeply sloping site.
Structural pre-cast concrete planks are employed throughout the project in effort to expedite the construction process, span large open areas and to provide the ability to heat the house hydronically. Combined with a 5” concrete slab and terrazzo flooring the structural system provides additional passive heating. Large overhangs on the glazed southern wall and the tree canopy minimize solar gain in the summer.
