Trinity Centre Could Become Housing: What Centreville Residents Should Watch

Centreville, Fairfax County | September 16, 2026

Trinity Centre could trade office space for housing—but the redevelopment is still a proposal. Fairfax County lists rezoning case RZ-2026-SU-00030 as Submitted. Stanley Martin Homes, LLC and JLB Trinity 2 LLC are seeking residential redevelopment on approximately 41.86 acres. View the county application.

The location makes this worth watching

The application places the site southeast of I-66, north of Route 29 and west of Route 28, with addresses along Trinity Parkway. It proposes attached homes, stacked townhouses and multifamily housing replacing existing offices. Source: Fairfax County.

For nearby residents, the meaningful question is how a residential neighborhood would work at street level: the walk to nearby destinations, the turns drivers need to make, and the timing of usable public space. Acreage alone does not answer those questions.

Two alternatives—not one approved home count

FFXnow’s September 15 report describes alternatives of up to 737 or 1,098 homes, with different apartment and condominium mixes alongside townhouses and stacked townhomes. It also reports proposed park space and a shared-use path along Trinity Parkway. These are reported application details, not a final approved plan.

The county adopted its broader Centreville Study plan amendment on June 23, 2026. That planning action and this individual rezoning are separate steps.

Three details to follow

• Housing mix: Apartments, condos and townhouses meet different needs. Follow the eventual mix and tenure, not just the maximum count.
• Access: Look for actual pedestrian connections and vehicle access arrangements. A path is most useful when it connects places people want to reach.
• Phasing: Ask when parks and connections would become available relative to homes. Amenities shown on a plan may arrive in stages.

Five questions about Trinity Centre

1. Is the redevelopment approved?

The public rezoning record currently says Submitted. It does not establish approval.

2. Are 737 and 1,098 homes being added together?

No. FFXnow reports two alternatives, not cumulative phases totaling both numbers.

3. Is this simply converting office interiors into apartments?

The county describes residential uses replacing existing office buildings. Do not assume an interior-only conversion.

4. How many homes would be designated affordable?

FFXnow reports an affordable-housing commitment but says a unit count is not specified. A specific count is not verified here.

5. Can buyers plan around a move-in date?

No verified completion date, home pricing or sales launch is established in the sources reviewed. Buyers with a firm deadline should compare available homes rather than count on this proposal.

Fairfax County housing snapshot: August 2026

These are countywide, all-property figures—not Centreville-specific results, live inventory or a forecast of this project’s effect. Fairfax City is excluded. Median-price change is not individual-home appreciation.
