Sherman residents have approved spending up to $50,000 on conceptual design services for the Sherman School.  During the town meeting on Saturday, about 60 residents turned out to discuss and vote on the funding.  The money will come from Sherman's capital non-recurring account.  Tecton Architects will come up with architectural designs and associated cost estimates for the school, which serves pre-k through 8th grade students.  The 1937 building has undergone a number of additions and renovations over the years.  Mechanical, plumbing and electrical repairs and replacement are needed.
