The principals of Horizon Properties have successfully planned and developed Mixed-Use Developments including Southpointe, a 589-acre project in Western Pennsylvania south of Pittsburgh. Rod Piatt, while at Millcraft Investments, and Michael Swisher, while at Team Plan Inc., were the key principals who developed the Southpointe Master Plan in 1985 and initiated private development at Southpopinte beginning in 1992. The execution of the Master Plan was led by them and included the development of the Southpointe Golf Course and Golf Club, Fairway Landings and Ironwood Residential Communities, The Iceoplex at Southpointe, Southpointe Commons and several office buildings.

The Southpointe project owes its existence to a unique partnership that developed between the private and public sectors that mutually set out to create a dynamic development with the goal of creating job opportunities for the residents of Washington County. The master plan for the 589-acre mixed-use development includes commercial and professional office sites, research and development, high technology and light industrial sites, single family home sites and town-home sites, an 18-hole championship golf course with a club house and a hotel and conference center scheduled for completion in 2001. Southpointe currently employs a workforce of approximately 4,000

Located on Interstate 79 in Cecil Township, Washington County, Pennsylvania approximately 15 miles from Pittsburgh and approximately 20 miles from the Pittsburgh International Airport, Southpointe is a high-quality development with well-developed infrastructure and excellent access. As such, Southpointe has established a regional reputation as a high-quality office and light industrial location and serves as a primary economic development catalyst for the region.
