A 168-unit affordable apartment community is planned for a portion of a 15.5-acre property in Largo, adjacent to another affordable housing project already underway on the site.

Tampa-based Southport Financial Services, working with Moore Bass Consulting, is seeking site plan approval from the City of Largo to build the complex at 800 8th Avenue Southeast, on the corner of 8th Avenue SE and Donegan Road.

The project, called Largo Station, would be built on 5.7 acres on the western portion of the property next to Allora, a 240-unit apartment community being developed by global real estate firm Trammell Crow Residential (TCR). The remainder of the property is occupied by Allora’s first phase. When both phases are complete, the site will have 408 apartments.

ARK Invest, a leading global investment firm known for its focus on disruptive innovation, will relocate its downtown St. Pete headquarters to the EDGE District.

Tampa-based Ellison Development announced Wednesday that ARK Invest, which is currently headquartered at 200 Central Avenue, will occupy 13,000 square feet on the 11th floor of Halcyon, a new office building expected to break ground later this year at 1301 Central Avenue.

Halcyon represents the first Class A office building constructed in downtown St. Pete since the 1980s.

The 11-story, 130,000-square-foot office building is one of the main components of The Central, a 2.1-acre mixed-use development that will also contain a 168-room Marriott Autograph Collection hotel, 14,000 square feet of retail space, a 42-unit affordable housing community, and a newly opened 540-space parking garage.
