3-Season Screened Porch

American University Park, Washington, DC

The three-season porch’s roofline and clerestory were designed to be sympathetic to the rooflines of the house, including a previous rear addition. Careful sitework protected an existing rose garden and patio.
Three-season porch (fitted with fixed glass panels in lower fenestration and removable screen and storm panels at eye level) enables year-round enjoyment of the garden; a clerestory provides both cross and stack ventilation; lattice panels conceal a storage area under the new porch.
A new stairway leads from the garden to a grilling deck at the side of the porch. Incombustible materials were utilized to fabricate the railing adjacent to the propane grill.
The new porch overlooks the homeowners’ garden, as well as the Japanese Embassy’s grounds and teahouse.
The homeowners are able to enjoy outdoor living while remaining protected from inconveniences such as mosquitoes, rain, and snow. The elevated porch enables views and cross-breezes and takes advantage of the home’s hillside setting.
The porch’s proportions (15’ x 18’) accommodates a generous seating area with sofas and a coffee table, plus a dining area with seating for six. Four infrared heaters provide sufficient warmth for year-round use.
The storage area below the new porch is equipped with a custom-made rack which houses the removable storm panels used to winterize the three-season porch. Black mosquito netting at the underside of the porch floor protects against insect infiltration.
The clerestory windows and paddle fans remove hot air from the porch. The ceiling paint color accentuates the paneled ceiling and recalls the blue sky. An engineered-wood decking system, a cost-effective alternative to Ipe, is barefoot-friendly and low maintenance. The sofa is positioned to take advantage of outside views outside or for TV viewing.
