The Birch at 51 Washington

304-Unit, Five-Story Luxury Community with Pool and Cast-In-Place Garage

The Birch at 51 Washington is a five-story luxury residential community in Conshohocken, Pennsylvania. With five stories of wood-frame construction over a two-level post-tension cast-in-place garage, the community features 304 units, amenities, and 366 parking spaces. Because of its location beside the Schuylkill River, the community includes flood vents and deployable flood barriers on the lower parking level as it sits in the floodplain. In addition, the team installed rammed aggregate piers which act as underground stone pillars to increase the density and bearing capacity of the building pad. The two light wells in the structure provide light to interior units as well as the outdoor amenities, such as a pool and several landscaped gardens. In addition, the community features a dog park, fitness center, pet spa, and virtual golf simulator. Located just outside of Philadelphia, The Birch at 51 Washington is a transit-oriented community with direct access to the SEPTA Conshohocken station and surrounding retail and restaurant options, such as Conshohocken Brewing Company and Flanigan's Boathouse.

our process
Overcame several obstacles—including asbestos, contaminated soil, concrete footings, and brick and abandoned fuel tanks—due to the project’s location on a previously developed industrial site.

Navigated an incredibly tight setting with the Schuylkill river to the South, an elevated bridge to the East, a train station to the North, and another active multifamily project site to the West.

Incorporated several unique elements to combat flooding such as AquaFence barriers, flood vents, and raised platforms for MEP equipment on the parking garage’s second level.
