Monadnock Ledger-Transcript Published: 10/14/2020 4:07:11 PM The Peterborough Planning Board discussed three proposals involving housing at their virtual meeting on Monday night. The Board got their first look at a three story multi-tenant building proposed for the lots on 104-108 Grove Street, which would house a dentist’s office and three apartments, briefly discussed a proposal to convert 28 Main Street, an all-commercial property, to a combination of commercial and residential uses, and granted a one-year extension to the development work at 63 Old Street, or the Stone Barn. Dr. Tae Kwon of Monadnock Perio and Implant Center assured the Board that he’d work closely with his architect and consultant to provide a formal proposal that meets the needs of the town. His dental office would occupy the ground floor of the proposed building on Grove Street, just down from the Dunkin Donuts. The building was designed to be about the same height as another white building nearby at the intersection of Route 101 and 202, architect Katie Sutherland said, with a peaked roof and a traditional New England façade. The building would have about a 2,000 square foot footprint with two 1,000 square foot two bedroom apartments on the second floor, and one on the third floor, Chad Branon of Fieldstone Land Consultants said. The dentist’s office is designed with five exam rooms to facilitate staggered appointments, Kwon said.
