Here are the 4 developers with visions for Hartford’s Bushnell South project; 2 are familiar names in redevelopment of the city

Two of the four developers submitting visions for a major redevelopment near the Bushnell Center for the Performing Arts in Hartford on the largest of a jumble of parking lots have built a total of hundreds of apartments in the downtown area in the last decade.

The two developers are Spinnaker Real Estate Partners LLC of Norwalk and Spectra Construction and Development of New York, associated with Wonder Works Construction Corp., the Capital Region Development Authority said Tuesday.

The field of developers is rounded out by Lennar Multifamily Communities (LMC) of Charlotte, North Carolina, which has an office in Stamford and its architect has worked on the North Crossing project near Dunkin’ Donuts Park; and Michaels Organization of New Jersey, which has an office in Boston, CRDA said.

Michael W. Freimuth, CRDA’s executive director, said the plans submitted by the four developers for the 3-acre lot just east of the renovated State Office Building at 165 Capitol Ave, would cost an average of $110 million to build.

The lot is part of the larger, Bushnell South redevelopment that could eventually have as many as 1,200 residential units — both rented and owned — restaurant, shops and entertainment venues.

The 3 acres is part of a larger swath of parking lots — both state- and privately-owned — and would include a broad, pedestrian promenade with restaurants and space for outdoor events. The promenade would be between a new park adjacent to the State Office Building and a block of apartments and townhouses.

Freimuth said he could not give specific details about each proposal because the quasi-public agency is still reviewing the proposals.

Freimuth did say they are all consistent with a consultant’s vision outlined last year. The focus of the review now underway is to find a partner that can be flexible as the development unfolds, particularly if market conditions change, rather than the project details, he said.

CRDA hopes to have a preferred developer selected this fall, Freimuth said.

Spinnaker Real Estate Partners LLC of Norwalk is already a partner in the Bushnell South redevelopment area with a $63 million conversion of the historic, 55 Elm St. into apartments. Spinnaker also has plans for new buildings on parking lots surrounding 55 Elm that are diagonally across from the 3-acre parking lot.

Spinnaker also is completing the $26 million apartment project at Park and Main streets.

Wonder Works Construction Corp of New York, a partner in the development of 560 rentals in the city beginning with the old Sonesta Hotel on Constitution Plaza in 2011. Wonder Works is now embarking on mixed-use conversions of downtown’s Pearl Street firehouse and the former municipal office building on Main Street across from city hall.

Lennar Communities is a developer of mixed-used properties across 19 states, including Connecticut, according to its website. In Connecticut, Lennar expects to complete a mixed-use, apartment high-rise in downtown Stamford for occupancy this winter.

The Michaels Organization is a developer of mixed-use projects in 35 states, including Connecticut, and the District of Columbia. In Connecticut, Michaels has developed 6 Solomon’s Crossing in New Haven and 11 Crown Street in Meriden.

Some downtown housing developers, including Martin J. Kenny, have been wary of adding another major housing project like Bushnell South before it’s clear how quickly new apartments at North Crossing and along Pratt Street are leased. Kenny is part of the Pratt Street project.

Freimuth said he disagrees.

“You don’t hit a button and development happens,” Freimuth said. “Development is an 18, 24, 36 month process. Realistically for us to get something done and get it launched, we need to start. It’s conceivable that we are 2, 3 years out from brick and mortar.”

Freimuth said the rental market in and around downtown has shown, so far, that it can lease new apartments. CRDA is keeping a close watch on leasing trends and projects could be slowed or quickened depending on those trends.

“This land has been laying fallow for 50 years,” Freimuth said. “Why do we have to keep on waiting?”
