If Fairfax County approves the Prosperity Business Campus’ transformation into a residential neighborhood, townhomes will likely be the first element of the project to materialize.
PM Home Associates, an affiliate of the developer EYA, hopes to build 156 townhouses, including 20 affordable dwelling units, as the first phase of its overhaul of the 41-acre industrial office park in Merrifield, according to a final development plan submitted to Fairfax County on Feb. 20.
Replacing four industrial buildings on approximately 8.3 acres of land northeast of the Prosperity Avenue and Hilltop Road intersection, the initial homes would come with transportation improvements as well as park space, a clubhouse and other amenities for the future residents and the wider community.
“This FDP represents the first step in transforming an aging, suburban-style industrial office park into a thriving residential community,” Walsh Colucci Lubeley and Walsh attorney Robert Brant said in a statement for the application. “… Future residents will enjoy these features along with the myriad of retail, dining, and recreational options in the Merrifield Suburban Center.”
Among other changes, this first phase of development would add two public streets extending east of Prosperity Avenue to the property line, including a new segment of Merrifield Avenue with a 10-foot-wide, off-street path for bicyclists and pedestrians that will ultimately connect to the existing road at Dorr Avenue.
The developer will also make some modifications to Prosperity Avenue and Hilltop Road, adding an 8-foot-wide sidewalk and landscape panel along the east side of the former street and a 10-foot-wide, off-street pedestrian facility along the latter.
“The existing curb along Prosperity Avenue will be relocated to the west, reducing the amount of asphalt and contributing to the road diet that has already been commenced by Fairfax County,” the application said.
In total, the first phase of the Prosperity Business Campus redevelopment will deliver 3.96 acres of open space, including 1.56 acres of urban parks, under EYA’s proposed plan. Envisioned as a “gateway” into the new community, the bulk of the park space would be located along Prosperity Avenue with a plaza at the Hilltop intersection and sidewalks, seating areas and lawns throughout.
Residents would have access to a private, 3,200-square-foot clubhouse with an outdoor swimming pool and unspecified indoor amenities.
“Together, the public and private open space amenities will provide a significant benefit for future residents and the larger Merrifield community,” Brant wrote in the statement.
According to the application, the townhouses will have four stories with a maximum height of 55 feet, and a fence will be constructed along the eastern property line to separate the new residences from the adjacent industrial buildings.
The developer has also committed to preserving “as many of the existing trees along Prosperity Avenue as possible” in accordance with guidance in the comprehensive plan amendment adopted by the Fairfax County Board of Supervisors on Nov. 18, 2025.
The 156 townhomes proposed by EYA would constitute the first phase of a larger mixed-use neighborhood with up to 1,900 homes, including a total of 332 attached townhouses and 1,568 multifamily units. The developer is also requesting an alternate option for up to 1,703 dwelling units, including 468 townhouses and 1,235 multifamily homes, in a rezoning application currently being reviewed by county staff.
Both options would include at least 5,000 square feet of non-residential space and focus the multifamily housing on the north portion of the site, closest to I-66 and the nearby Dunn Loring Metro station, according to the rezoning application.
A proposed phasing plan that was recently added to the application shows EYA anticipates constructing all of the townhomes first before turning to the multifamily blocks, designating a building northwest of the Prosperity and Hilltop intersection as the “potential” sixth and final phase.
The Phase 1 development plan hasn’t been accepted by county staff for review yet, but the larger rezoning application is currently scheduled to be discussed by the Fairfax County Planning Commission and Board of Supervisors at public hearings on June 10 and July 14, respectively.
