A new redevelopment proposal in Merrifield could turn part of an aging office and industrial campus into a residential community, with 156 townhomes planned in the first phase at Prosperity Business Campus near Prosperity Avenue and Hilltop Road. According to FFXnow, the first phase would also include 20 affordable dwelling units, open space, a clubhouse, a pool, and transportation improvements.

What Is Being Proposed in Merrifield

The proposal centers on the 41 acre Prosperity Business Campus in the Merrifield Suburban Center. Fairfax County’s adopted plan amendment says the Board of Supervisors approved updated land use guidance for the site on November 18, 2025, allowing it to be considered for residential mixed use redevelopment up to 1.35 FAR. The county planning page also says the change was intended to evaluate public facility impacts, transitions to nearby residential areas, and stronger connections to the Dunn Loring Transit Station Area and Mosaic District Town Center.

The county’s adopted text makes the long term vision clear. With full site consolidation, Prosperity Business Campus may be redeveloped as a more walkable mixed use residential neighborhood with publicly accessible parks, a mix of housing types, improved bicycle and pedestrian access, and at least 5,000 square feet of ground floor non residential space. The plan also says the primary housing form should be multifamily units, while townhomes or similar formats can help create transitions to lower density homes nearby.

Why This Matters for Merrifield

This is not just another townhouse proposal. It is part of a broader shift in Merrifield away from older suburban office parks and toward more connected, mixed use neighborhoods near transit. Fairfax County’s adopted plan text specifically calls for better pedestrian and bicycle connections, a shared use path along Prosperity Avenue and Hilltop Road, and a pedestrian connection toward Dunn Loring Village. It also points to publicly accessible parks and open space as defining features of the redevelopment.

That matters because Merrifield is already one of the more active pockets of Fairfax County for reinvestment, especially with its proximity to Dunn Loring Metro, Mosaic District, I 66, and major employment hubs. Projects like this can reshape how people move through the area, what kinds of homes are available, and how future buyers think about the neighborhood’s appeal. This redevelopment is also designed to create a more urban, pedestrian oriented environment rather than simply replacing one low rise office park with another auto focused project.

What the First Phase Includes

Based on the FFXnow report, the first phase would redevelop about 8.3 acres northeast of the Prosperity Avenue and Hilltop Road intersection. It would replace four industrial buildings with:

• 156 townhomes
• 20 affordable dwelling units
• 3.96 acres of open space
• 1.56 acres of urban parks
• A 3,200 square foot clubhouse
• An outdoor swimming pool
• New streets and pedestrian improvements tied into the broader future redevelopment plan

The report also says the townhomes would be four stories tall with a maximum height of 55 feet, and a fence would be built along the eastern property line to buffer the homes from adjacent industrial uses.

Transportation and Walkability Could Be a Big Part of the Story

One of the most important parts of this proposal is not just the housing count. It is the street and pedestrian network that comes with it. FFXnow reports that Phase 1 would add two public streets extending east from Prosperity Avenue, including a new segment of Merrifield Avenue with a 10 foot off street path for pedestrians and cyclists. It would also add an 8 foot sidewalk and landscape panel along Prosperity Avenue, plus a 10 foot off street pedestrian facility along Hilltop Road.

That lines up with Fairfax County’s adopted plan language, which encourages a more active transportation focused design on Prosperity Avenue and Hilltop Road and recommends that redevelopment accommodate future grid streets and shared use paths. In practical terms, that means the project is about more than homes. It is also about making this part of Merrifield easier to navigate without relying entirely on a car.

A Useful Way to Think About the Bigger Picture

For people who know Merrifield mostly as a mix of offices, light industrial buildings, and busy roads, this proposal is a sign of where Fairfax County planning is headed. The county’s adopted guidance explicitly supports transforming the site into a more vibrant residential mixed use environment, with architecture, parks, services, and mobility features designed around a growing residential population.

FFXnow quoted the application as calling this the “first step in transforming an aging, suburban style industrial office park into a thriving residential community.” That line is one of the clearest ways to understand the goal of the project, and you can read the original reporting here on FFXnow.

What Comes Next

According to FFXnow, the first phase development plan had not yet been accepted by county staff for review at the time of that February 26, 2026 report, while the broader rezoning application was then expected to go before the Planning Commission and Board of Supervisors later in 2026. Fairfax County’s public hearings hub is the best place to monitor what happens next as schedules and staff reports are posted. Fairfax County Public Hearings and Staff Reports is a good page to bookmark if you want to track the case.

Final Thoughts

For Merrifield homeowners, buyers, and investors, this is the kind of project that can influence the area for years to come. More housing, added affordability, new open space, and better pedestrian connections could all strengthen Merrifield’s position as one of the more dynamic submarkets in Fairfax County. At the same time, the public review process will matter, especially when it comes to traffic, transitions to nearby neighborhoods, and how well the final design delivers on the walkable mixed use vision Fairfax County has outlined.
