Perimeter Summit’s building spree is not slowing down. High Street Residential has filed plans for a second phase of its Residences at Perimeter Summit project, lining up roughly 280 additional rental units on a 2.7-acre lot next to the seven-story apartment building that is already rising. The new phase would tuck in ground-floor commercial space and two restaurant pads along Lake Hearn Drive, tightening the knot of housing and retail around the Perimeter office hub.
What Was Filed
ConnectCRE reports that High Street’s latest submission calls for about 280 apartments, roughly 5,000 square feet of commercial space and 28 workforce housing units. The buildings would fill a vacant 2.7-acre site between Lake Hearn Drive and Summit Boulevard, a gap site that has been sitting between offices, new apartments and retail.
An Anchor Project Already Under Construction
High Street Residential has already broken ground on the first phase of Residences at Perimeter Summit, a seven-story, 350-unit mid-rise the company lists at 1251 Perimeter Summit Parkway. The project’s amenity list reads like a checklist for modern renters, with a resort-style pool, clubroom and coworking spaces pitched to lure both remote workers and office regulars, according to High Street Residential. That initial phase is slated to deliver in late 2026.
Perimeter Summit Is Shifting Toward 24-Hour Use
Perimeter Summit totals roughly 1.7 million square feet of office and retail, and ownership has been working to reposition the 83-acre campus as a true mixed-use destination with more than just daytime foot traffic, according to JLL. Across Lake Hearn Drive, the AMLI Brookhaven project brought about 630 apartments and roughly 20,000 square feet of retail online last summer, a shift the Atlanta Business Chronicle notes has already changed how walkable the area feels.
City Traffic Study Finds Modest Impacts
Brookhaven’s updated traffic study for the land-use petition lists Phase 2 at 269 dwelling units, a slightly more precise figure than the rounded 280-unit tally. The city’s analysis estimates about 110 morning peak-hour trips and 104 evening peak-hour trips tied to the new building and concludes that nearby intersections would continue to operate at acceptable levels with the added traffic, according to City of Brookhaven filings. The study models conditions through 2028 and recommends specific access and turning movements intended to keep queues in check.
Workforce Housing And Retail
ConnectCRE also notes that the proposal includes 28 workforce housing units, plus two restaurant spaces fronting the AMLI development across the street. The relatively small commercial footprint is framed as a convenience play for both residents and office workers, with local planners and the developer describing the retail as a complement to the existing office amenities rather than a standalone shopping destination.
Why Developers Are Making The Bet
Owners and the Perimeter Community Improvement Districts have been leaning hard into a strategy that mixes offices with dining, programmed events and better pedestrian connections, a formula they say helps justify more apartments and neighborhood-scale retail. “Perimeter is now a 24-hour community,” Perimeter CIDs told the Atlanta Business Chronicle, a line High Street and other builders appear to be treating as a market thesis rather than a slogan.
Next Steps
According to the city’s project page, Brookhaven’s planning commission deferred its hearing on the proposal to April 1, with the Mayor and Council set to take up the land-use petition on April 28. If the plan is approved, the second phase would add dozens more rental homes to an already brisk development pipeline in the Perimeter area. Final conditions, along with any required traffic or design mitigations, will be hammered out through those public meetings and staff review, and city documents along with the formal project packet will remain the most detailed record of what High Street is asking to build.
