Progress continues on 3d & 3rd, a 33-story luxury apartment tower coming soon to downtown St. Pete | St Pete Rising

This quarter’s edition of Aerial St. Pete shows the progress of six residential developments currently under construction in St. Petersburg.

With the help of AB3 Visuals, we track the progress of two downtown condo towers nearing completion, a downtown apartment tower close to topping out, a mid-rise apartment building planned for north St. Pete, an apartment community that will include a retail village, and the largest mixed-use project currently planned in the city.

St. Pete Rising looks forward to keeping you informed on St. Pete’s development scene, and we’ll continue tracking these projects as they near completion.

Residences at 400 Central
400 Central Avenue

The 46-story Residences at 400 Central luxury condo tower is nearing completion in downtown St. Pete.

The first 25 floors received a Temporary Certificate of Occupancy (TCO) earlier this week and residents are expected to begin moving in this month.

The tower contains 301 condominium residences ranging from one to four bedrooms, along with 40,000 square feet of Class A office space and 60,000 square feet of ground-floor retail.

Foundation work began in late 2022, and the project secured a $252 million construction loan in early 2023. The tower topped out in January.

In June, developers announced that Dynasty Financial Partners would lease the tower’s office space. A month later, they revealed the project’s first retail tenant, Volta Wine + Market, which will take 2,000 square feet along Central Avenue. And last month, PNC Bank was confirmed as another addition, with a 3,000-square-foot branch also planned for Central Avenue.

A standout amenity will be the 46th-floor Sky Lounge Observatory, offering panoramic views of Tampa Bay and the Gulf of Mexico.

More than 85% of the residences are under contract, with remaining units priced from $1 million.

The project is being developed by Red Apple Group, with Suffolk Construction serving as general contractor. Sales are being handled by Michael Saunders & Company at a sales gallery located directly across the street at 465 Central Avenue.

Art House
235 1st Avenue South

The 42-story Art House luxury condo tower received its Temporary Certificate of Occupancy (TCO) in late November for floors 10 through 32, allowing the first closings to begin.

The building, located at 275 1st Avenue South, contains 244 luxury condos and is more nearly 90% sold. The remaining units are priced from $1.3 million to over $7 million.

The project was announced in early 2022 by Kolter Urban, the South Florida-based firm behind ONE St. Petersburg and Saltaire.

Coastal Construction broke ground on the tower in June 2022, and the tower topped out in November 2024. Full completion of the building is expected in early 2026.

At street level, the tower includes 4,936 square feet of retail space along Central Avenue. The space is currently listed for sale at $5.7 million and is represented by Wendy Giffin of Cushman & Wakefield.

The development team is comprised of SB Architects, ID & Design International, and Kimley-Horn. Smith & Associates is serving as the exclusive broker for the condo tower.

3rd & 3rd
235 3rd Street South

Vertical construction continues at 3rd & 3rd, a new luxury apartment tower rising at 235 3rd Street South in downtown St. Pete, where 25 of the planned 33 stories are now in place.

The project is being developed by St. Pete-based Echelon in partnership with Tampa-based Third Lake Capital and will contain 268 rental units and over 15,000 square feet of ground-floor retail and restaurant space.

The ground-floor retail space is currently available for lease.

Residences will range from studios to two-story penthouse units, all featuring high-end finishes and modern appliances.

Construction began in 2024, with vertical construction starting earlier this year. Completion is anticipated in late 2026. KAST Construction is serving as the project’s general contractor.

In addition to 3rd & 3rd, Echelon is also leading the development of Echelon City Center, a 20.5-acre master-planned community in north St. Pete that will include at least 2,300 residential units and nearly 150,000 square feet of retail space at completion.

Echelon has also proposed a 31-story twin-tower development at 800 2nd Avenue South in downtown St. Pete, which would include 824 apartments and more than 35,000 square feet of ground-floor retail.

Trinity Pointe at Echelon City Center
100 Main Street North

Construction is progressing on the 14-story Trinity Pointe luxury apartment tower, previously referred to as Sites 7 & 8, at Echelon City Center in the Carillon Office Park in north St. Pete.

The 363-unit development will include more than 17,000 square feet of retail and restaurant space, a four-level parking garage, and secure bicycle storage. The building will offer a mix of residences, including three-story townhomes with high-end amenities.

A sixth-floor amenity deck will feature a swimming pool, outdoor gaming and lounge areas, an indoor fitness center, a clubroom, virtual sports simulator, and co-working space.

The project is being developed by St. Pete-based Echelon, designed by ARC3 Architecture, and built by KAST Construction.

The building topped out earlier this year and completion is expected by summer 2026.

At full completion, the Echelon City Center will have over 2,300 multifamily units and nearly 150,000 square feet of retail space.

Sky Town
3201 34th Street South

Sky Town is a major redevelopment of the former Ceridian office campus in the Skyway Marina District in south St. Pete.

The 34.2-acre site at 3201 34th Street South is being developed by Coral Gables–based developer Altis Cardinal in six phases and will ultimately deliver 2,084 apartments, 69,000 square feet of neighborhood retail anchored by a Sprouts Farmers Market, and 120,000 square feet of self-storage space.

The first residential building broke ground in September and will include 401 apartments, 121 of which will be designated affordable.

Of those 121 affordable units, 61 will be reserved for households earning up to 120% of the area median income (currently $103,200 for a family of three), and 60 will be set aside for households earning up to 80% of the area median income (currently $68,800 for a family of three).

The remaining 280 apartments in the first phase will be offered at market rates.

Sprouts officially opened on November 14th, marking the first major completion for the project.

Meanwhile, the parking structure for the apartment building is expected to be fully completed next week.

A number of retail leases are also in active negotiation for both the outparcel building and the apartment building currently under construction, signaling strong tenant interest as the development continues to take shape.

St. Petersburg City Council previously approved a $4.5 million contribution from the Housing Capital Improvement Fund to support the affordable housing in the project’s first phase. The developer also secured a $68 million loan from Fifth Third Bank.

The first phase of Sky Town is expected to be complete by the fourth quarter of 2026.

The Henry at Whitney Village
3200 1st Avenue South

Construction is underway on The Henry at Whitney Village, a 325-unit apartment community that will anchor a new live-work-play neighborhood in St. Pete’s Grand Central District.

The five-story apartment building, which is being developed by Greystar, is part of a larger development, which will also include a 32,000-square-foot pedestrian-only retail village and a 600-space parking garage for residents and visitors.

The mixed-use project will occupy 4.5 acres on the east side of the Jim & Heather Gills YMCA at 3200 1st Avenue South.

Groundbreaking on the multi-family building took place in May with completion expected in March 2027. Pre-leasing is scheduled to begin in December 2026.

The 25-year-old, 55,000-square-foot YMCA is also undergoing a major renovation funded by proceeds from the sale of the athletic field property.

Greystar is partnering with California-based real estate investment and management group Griffin Capital to develop the apartment community and St. Pete-based investment firm Blake Investment Partners to develop the retail village, which has yet to break ground.
