Portman targets Alpharetta office park for major redevelopment Josh Green Tue, 12/10/2024 - 14:10 Paperwork filed with the State of Georgia indicates prominent intown developer Portman Holdings has set sights on Alpharetta for its next large project.

Portman is compiling plans to convert an office park about a mile and ½ east of Avalon into a mixed-use district with hundreds of new residences, according to a Development of Regional Impact filing made Monday with the Georgia Department of Community Affairs.

The Alpharetta site in question is home to two office buildings—Brookside One & Two—and large asphalt parking lots along Old Milton Parkway (Ga. Highway 120). According to LoopNet, the Class A buildings total about 266,000 square feet.

According to the DRI filing, roughly 130,000 square feet of occupied offices would remain onsite, with the rest converted into residential, commercial, and retail uses.

Specifically, Portman’s plans call for building 350 multifamily units, 90 townhomes, and 60,000 square feet of commercial and retail space from Brookside’s current buildings and parking lots.

The project’s estimated completion date is listed as 2029. We’ve reached out to Portman officials for more project details and will update this story with any additional information that comes.

As a first step toward redevelopment, Portman is filing the project with the state for review as a possible DRI. The DRI classification, which applies to projects large enough to effect multiple jurisdictions, is meant to streamline the development process and gather local input.

As it currently stands, the Brookside property counts four parking spaces for every 1,000 square feet of offices, with a new outdoor courtyard as its centerpiece. A trail system nearby links with the Big Creek Greenway, a miles-long destination for biking, walking, and jogging.

According to CBRE marketing materials, the property underwent a multi-million-dollar renovation, completed in 2022, that included a new conference center, lounge, and lobby for both buildings. The goal was to “enhance tenant wellness and productivity,” per the commercial real estate firm.

Closer to its downtown Atlanta home base, Portman has made no shortage of development-related headlines in recent years.

The company officially debuted metro Atlanta’s largest office project of 2024 last week, and it continues to deliver restaurant options to the Beltline’s most active stretch at its Junction Krog District project in Old Fourth Ward.

Elsewhere along the Beltline, the company has scaled back redevelopment plans for Amsterdam Walk in the face of community pushback and cut ties entirely with a massive proposal along Ponce de Leon Avenue, citing economic headwinds.
