The second half of 2025 saw a rush to build new housing in the Northern Virginia area, including these five residential and mixed-use real estate developments.

Prince William County

The Hoadly Square and Maple Valley Grove projects will add a combined 550 units near the Occoquan Reservoir Protection Area. That plan didn’t sit well with some residents at a December 2025 Board of Supervisors meeting.

Maple Valley Grove will sit on about 23 acres on the south side of Prince William Parkway, west of the intersection of Hoadly Road. Hoadly Square will take 48 of its 58 acres from the reservoir protection area itself.

The latter development, by J.R. Real Estate Group, plans to keep about 60% of the land as open space.

Most supervisors and some of the residents who spoke at last month’s meeting felt that the county’s need for affordable housing made the developments too important to pass up. But many residents felt the developments would have environmental impacts on the reservoir. They were also concerned about traffic congestion around the Dar Alnoor Mosque and overcrowding at Colgan High School.

Supervisor Kenny Boddye said that J.R. Real Estate had made a commitment to well testing and stormwater management. And that some of the protections involved in the zoning changes would represent improvements over the current ordinance.

“Done responsibly,” Boddye said, “infill projects can protect more land, not less.”  

Supervisor Yesli Vega cast the only vote against the projects. “It is my opinion that the community should not, in any way, shape, or form, be forced into an either-or scenario between housing or clean water,” Vega said. 

Fairfax City

The Botanist, a mixed-use building with more than 200 residential units, is proceeding at 10350 Eaton Place. The site is near Fairfax Boulevard and Chain Bridge Road.

The city says that the project will replace a parking lot at the WillowWood office plaza with up to 260 apartments. It will include around 5,000 square feet of retail space on the ground floor and a parking garage.

The land and financing for The Botanist were secured last August, Fairfax Now reported. The city says that they approved and released the site plan in October. Capital City Real Estate is the developer, and 16 of the units will be designated as affordable housing.

One of the most visible empty buildings in the Northern Virginia area has been knocked down. And its planned replacement looks to be striking in its own way.

Demolition of the Key Bridge Marriott took most of the second half of last year. Now Quadrangle Development envisions five buildings on the site, with room for about 1,775 residential units and a 200-room hotel. The project includes five buildings, and the developer says the area will include plenty of “green spaces, pathways, and view corridors” in between.

“Our design purposefully invites the public in to enjoy this unique water view property offering outstanding views over the Potomac River and toward the Nation’s Capital,” Quadrangle president Christopher Gladstone said in a statement.

Fairfax County

A mixed-use development with 450 apartments and 30,000 square feet of retail is being planned for the Seven Corners area.

The new development, from Falls Church-based Eakin Properties, would comprise two buildings, an outdoor plaza, and parking. It would take up a little over three acres between Arlington Boulevard and Hillwood Avenue, where Pistone’s Italian Inn and New Grand Mart currently stand, Virginia Business reported.

The mixed-use nature of the project will require a zoning change, as the site is currently zoned for retail. Before that, though, the Board of Supervisors will have to vote on an amendment to the comprehensive plan, Virginia Business said. Work on that amendment began last summer.

Valley Drive Village

Fairfax County is also home to possibly the newest recent residential development. Earlier this month, the supervisors approved the rezoning necessary to build the Valley Drive Village project. It will bring about 450 units to the McNair Farms area.

The project includes about 244 apartments and 200 townhouses to replace two office buildings in the Dulles Technology Center, Fairfax Now reported.

About a quarter of the area of the site will remain as open space. Developers Mandrake Capital Partners will give Fairfax County Public Schools $2,500 per unit for new school construction, as well as $15,000 for each student whom the development is expected to generate.

The site plan still needs board approval.
