3-Story Deck Installation in Washington, DC

This three-story deck build in NW Washington, DC was designed and installed in collaboration with a structural engineer to meet the city’s strict permitting and safety requirements. Space was tight, so we incorporated a cantilevered staircase—allowing the homeowner to keep valuable parking underneath while maintaining full functionality and flow.

To protect the building’s roof where the top deck sits, we installed a new TPO membrane and added sacrificial protection layers anywhere framing made contact. Every detail was engineered for longevity, including custom galvanized Simpson Strong-Tie hardware, which we had hot-dip galvanized in Baltimore for superior corrosion resistance.

Using triple 2x12 beams, we achieved wider open spans and a more open, modern feel across all three levels. The result is a structurally solid, code-compliant deck that feels spacious, durable, and built to last.
