Our Story

Fourth River Development (FRD) was established in 2006 to continue the founders’ previous decades of commercial real estate experience, knowledge and successful projects that created, managed and leased over 4 million square feet of real estate. FRD provides its clients a one-stop-shop real estate firm that works from an “Owners Perspective” on any and all projects. This style of business provides the necessary tools and expertise focusing on creating long term value and economic benefits to clients, whether they be partners, owners or tenants.

With a portfolio consisting of both commercial and residential properties, including but not limited to, ground-up construction and renovation of existing properties, brownfield and greenfield sites, public-private partnerships and smart growth communities, FRD is here to suit a client’s every real estate need.

Some of the projects and developments we have been involved in are: the Class A office redevelopment of 225 Boulevard of the Allies in downtown Pittsburgh; the ground-up development of the Marshall Village retail strip center in Warrendale, PA; the development of the 70,000 square foot regional headquarters and manufacturing plant and 140,000 square foot expansion for Hörmann Flexon in the Starpointe Business Park in Burgettstown, PA; the Starpointe Business Park located in Washington County, Pennsylvania – a 1,200-acre mixed-use Park devoted to office, manufacturing, and warehouse distribution companies; the leasing and development of a 228,000 square foot build-to-suit Class A office building for Alcoa on Pittsburgh’s North Shore; Summerset at Frick Park, Pittsburgh’s “New Traditional Neighborhood” consisting of a $243 million redevelopment on a 240-acre brownfield site that will ultimately house 713 families; and Washington’s Landing – a mixed-use waterfront project including 5 office buildings, 88 townhomes, tennis courts, parks and walking trails.
