Beautifully located in the historic neighborhood of the Bunker Hill Monument, the owners of this two-family home wanted more room to meet their growing family’s needs. With tight zoning regulations and an even tighter site, there was only one location to expand. The roof top of an existing two story addition commonly known as an “ell” could sustain another floor and be below the existing roof height, a condition of zoning. Carefully crafted, the new master suite and renovated guest bath were efficiently tucked into a 230 square foot addition. The oriel, reaching the limits of zoning, allows for additional space in the master bedroom while adding Charlestown charm. In association with JDP.
