A San Diego real-estate firm says it wants to transform the floors above the CVS on Summer Street in Downtown Crossing into life-sciences labs and offices.
In a letter of intent filed with the BPDA, Phase 3 Real Estate Partners says the move would "broaden the range of potential tenants" for a 10-story building that originally went up as a headquarters for the Charlestown Savings Bank in 1974.
Phase 3 bought the building last March from locally based Synergy for $10.6 million.
The company says it would not change the basic footprint of the building, but would add beefier mechanical equipment to the roof to handle the extra needs of biotech labs.
The company says the CVS would remain in place, but in front of plaza that Phase 3 plans to spruce up.
Phase 3 says it will soon file detailed plans for its proposed redo of the building and plaza.
