A massive array of solar panels could provide cover for the office building that developer Rushmark Properties and the construction company HITT Contracting are planning to build at Virginia Tech’s campus near the West Falls Church Metro station.
In a final development plan recently submitted to Fairfax County, the two companies — collectively known as Converge West Falls LLC — propose installing a photovoltaic array canopy on top of the building, which will house HITT’s corporate headquarters and laboratory space for Virginia Tech’s planned National Center for Smart Construction.
Standing approximately 117 feet tall, the canopy would encompass approximately 112,000 square feet, making it larger than the roof of the 270,000-square-foot building. It would have nine support columns ranging in height from 91 to 111 feet, per the application.
“The tree-like columns provide a structural solution while also creating the sense of lift and grandeur emulating a modern woodland canopy,” Walsh Colucci land use lawyer Andrew Painter said in a Nov. 22 statement for the applicant. “The multifunctional solar array canopy also shades the building from the sun, as one of the proposed building’s energy-reduction measures.”
The array is expected to generate between 1,100 and 1,400 megawatts of electricity — enough to supply most of the building’s energy, the application says.
The solar panels are one of several amenities detailed in a trio of plans filed last week to expand Virginia Tech’s Northern Virginia Center at 7054 Haycock Road.
Block A
Most of the office building — 230,000 square feet — would be devoted to HITT’s headquarters, but Virginia Tech would have up to 40,000 square feet on the northern side for educational purposes. A maximum height of 97 feet and six stories has been proposed.
Under the submitted plan, the building would be served by a below-grade parking garage and a 23,500-square-foot entry plaza on the south side with built-in benches, movable tables and chairs, “playful” lighting, and garden areas with native tree, pollinator and flower plantings.
“A large depression pond that exists on the site will be repurposed into a bioretention garden to treat stormwater run-off and provide visual interest along Falls Church Drive,” Painter wrote.
Block B
Further south on the 7.5-acre site between Mustang Alley and Falls Church Drive will be a 532,000-square-foot multifamily building with 440 residential units and 18,000 square feet of ground-floor retail.

Converge is planning to offer a mix of one, two and three-bedroom units that “will be larger than the current industry trend to better accommodate families,” according to the application. The building will be up to 139 feet tall, descending to 82 feet along Falls Church Drive. Read More

A developer has officially filed plans with Fairfax County to bring housing, retail, and new office and academic facilities to Virginia Tech’s campus in Idylwood.
As a joint entity named Converge West Falls LLC, real estate investment firm Rushmark Properties and the construction company HITT Contracting have proposed replacing the existing Northern Virginia Center at 7054 Haycock Road with a 283,000-square-foot office building, up to 440 residential units, and a 2,000-square-foot retail pavilion.
Submitted last Thursday (Sept. 22), the application fleshes out an agreement made earlier this year between Converge and the City of Falls Church, which intends to sell the approximately 7.5-acre site to the developer.
The project will “serve as a logical connection” between the West Falls development on Falls Church’s former George Mason High School property and a planned redevelopment at the West Falls Church Metro station, Walsh Colucci land use attorney Andrew Painter wrote in a statement of justification on Converge’s behalf.
Rushmark is also involved in the Metro project, which will turn the Metro station’s existing parking lots into housing and office buildings with some retail.
Reviving a stalled plan between Virginia Tech and HITT, Converge’s Northern Virginia Center proposal features roughly 820,000 square feet of development across three buildings on two blocks west side of Falls Church Drive and north of Haycock Road:
- Building A: A 283,000-square-foot office and education facility that will house HITT’s corporate headquarters and a 40,000-square-foot laboratory space for Virginia Tech, dubbed the National Center for Smart Construction (NCSC)
- Building B: A residential building with up to 440 units and approximately 16,000 square feet of ground-floor retail uses. It will have a maximum height of 15 stories and 145 feet, providing parking in a 2.5-story underground garage.
- Building C: An approximately 2,000-square foot one-story retail kiosk/pavilion
If approved, the project would link the West Falls and Metro developments by extending the former’s central West Falls Station Blvd through the property. Building C would be in the center of the street’s 12,300-square-foot, publicly accessible median.
Straddling the boundary between the city and Fairfax County, the “Median Green” will also serve as a green space with landscaping, trees, movable tables and chairs for “informal gatherings,” open lawn areas, an outdoor stage or performance space, and public art.
Other proposed amenities include entry plazas for both the office and residential buildings and public gardens on Haycock Road and Falls Church Drive. The latter’s garden would feature a bio-retention rain garden.
The developer says it will also provide approximately 0.29 acres of publicly accessible open space on the Metro redevelopment site as well as private, “vegetative” roof decks for the office and residential buildings.
“Building A’s office roof will, for example, feature outdoor working and social spaces with lush planters and stormwater areas,” the application says. “The Building B’s residential roof deck will include a pool, recreation lawn, and seating terraces.”
As part of its transportation commitments, the applicant says it will upgrade the existing sidewalks on Haycock Road and Falls Church Drive, provide bicycle racks, and extend bicycle lanes planned for West Falls Station Blvd through the development. A total of 1,138 parking spaces will be provided.
“When constructed, this new neighborhood will function as one larger transit-oriented neighborhood,” Painter wrote. “The proposed NCSC facility will serve as a hub for research and testing of emerging construction methods, materials and technology that will inform Northern Virginia’s construction and real estate industries. Further, the proposal will attract individuals who think creatively, share ideas, and drive daytime demand locally-serving office and retail uses, as well as Metrorail ridership.”

A redevelopment of Virginia Tech’s Northern Virginia Center (7054 Haycock Road) in Idylwood is back on the table.
The Falls Church City Council authorized agreements on Monday night (July 25) that will terminate the university’s 40-year lease for the 2-acre parcel and allow the city to sell the land to Converge West Falls LLC, an entity of developer Rushmark Properties.
Advanced by Virginia Tech’s board in April, the exchange will revive a plan to build a new design school, a headquarters for the construction company HITT Contracting and more on the Northern Virginia Center campus that abruptly collapsed in early 2021.
“Virginia Tech has a long history in the City of Falls Church and we are excited about this new chapter,” Virginia Tech Media Relations Director Michael Stowe said. “This vote moves us a step closer to creating a world-class smart construction research center in collaboration with HITT Contracting, and it means the community will benefit from a vibrant, mixed-use district that will transform the neighborhood.”
According to a city staff report, the Northern Virginia Center is a 101,000-square-foot office building on a larger, 7.4-acre site located in Fairfax County but owned by Falls Church, which has leased a portion of the land to Virginia Tech since 1995.
Under Falls Church’s new agreements with Virginia Tech and Rushmark, the city could sell the full site to the developer for $25 million, including $16.57 million that it would then pay to the university. The resulting development must feature:
- A 240,000-square-foot office building for HITT’s corporate headquarters, including at least 40,000 square feet for a Virginia Tech National Center for Smart Construction
- 440 residential units with ground-floor retail
- Construction of a West Falls Station Blvd through the site, among other road improvements
The project still has to go through a number of steps to come to fruition. First, Virginia Tech has to get the governor’s approval for its planned land transfer to the city, and then, Rushmark must submit its plans to Fairfax County.
“Virginia Tech will continue to occupy the site, with no rent payments to the City, until the final closing date, which is no later than March 31, 2025,” the staff report said. The agreements are expected to be closed sooner than that, coming within 30 days of zoning and site plan approvals from the county. Read More
