525 Amherst Street is an adaptive reuse of an A&P Supermarket building, in Winchester, Virginia that was converted to a medical office building. The original supermarket structure was built on an alluvial plain from an ancient creek bed, presenting structural bearing challenges that required creative problem solving including the use of helical piers and engineered soil replacement to safely support and preserve the building. The design of the new building form is a reference to the historic hexagonal house across the street and the museum of the Shenandoah Valley next door. The base building includes an arcade along the front with an air lock entry feature for indoor air quality control as well as updated building systems. This adaptive reuse project was 21,380 square feet with a budget of $1.9 million. Since the completion of the base building in 2005, MSA’s interior design department designed all the tenant fit out projects within, including an eye surgery suite, a cancer wellness center, and a home health supply store for Valley Health.
