Developer Chip Norton of Franklin Realty Advisors LLC plans two large-scale projects in downtown Worcester Massachusetts including a 150-unit apartment building on Front Street and 125-room hotel on the corner of Mercantile and Foster Streets. The proposals would significantly add to Norton’s holdings at the Mercantile Center complex, which already includes the 100 Front St. skyscraper, the office building at 120 Front St., and a parking garage. The hotel would be located next to 2 Mercantile St., one of Norton’s other development projects which is nearing completion. Norton’s proposal for a 150-unit apartment building would be constructed at 90 Front St. above the two-story property which currently houses a CVS pharmacy and the Worcester District Registry of Deeds. The apartments would be market-rate, according to Norton’s presentation to the improvement district. Norton is still exploring partners for the two projects.
