901 15th Street, McPherson Building Rooftop

Washington, DC

Deceder Group transformed the underutilized rooftop of the McPherson Building into a premium indoor/outdoor amenity that strengthens the property’s position in one of D.C.’s most active office corridors. The multi‑floor repositioning introduced new pathways on the 11th and 12th floors, a purpose‑built steel structure at the penthouse, and a nanawall system that opens the interior lounge to a refined terrace. The result is a high‑end, flexible, future‑ready amenity that enhances tenant experience and long‑term asset value.
