About

I build buildings, shape communities, paint paintings, and travel to learn.

Bob Elliott is a native Washingtonian. He was trained as an architect at Rice University and at Murphy/Jahn in Chicago, then pivoted to development through Wharton's MBA program. He spent two years in London at BuildOnline and UrbanCapital, returned to Washington, and worked at JBG, Clark Enterprises, and Washington REIT through the 2000s and into the mid-2010s. Since 2016 he has led River Falls Investments (formerly Lantian Development) — a privately-held firm with a 540-acre portfolio across the DMV.

Some of the work that forms the local public record includes the U.S. Department of Transportation Headquarters at 1200 New Jersey Avenue SE, the McDermott Will & Emery anchor lease at 500 North Capitol, the Silverline Center re-skin in Tysons Corner, the 2021 sale of the Shady Grove Bio+Tech Campus to BXP, and the transformation of 255 Rockville Pike in Rockville Town Center, close to home. The current focus is 22300 Comsat Drive — 204 acres in Clarksburg where Cesar Pelli's 1969 COMSAT Laboratories has just begun coming down — and an 8.6-megawatt solar array in Oxon Hill. The record is partial; not all of the work has been local, and not all of it is on this page yet.

At the scales these parcels tend to land — 75, 100, 200, even 540 acres — they aren't just buildings. They are communities, infrastructure, mixed-use places that shape how people live, work, and move. The architecture training underwrites all of it: every parcel begins as a question about how it could be drawn before it becomes how it gets financed, entitled, and built.

Painting is the other side of that brain — the creative outlet that runs in parallel. Red Line, a four-by-eight-foot panel, has hung in the Bethesda Metro pedestrian tunnel since 2012; more sit in studio. He has served on the VisArts board since 2016. He has been to sixty countries and all fifty states, and tries to bring something back from each — the conviction that travel is its own form of urbanist apprenticeship runs through the rest. The site you are looking at is part of that — a layered artifact, each overlay drawn on top of the last.
