The original house was built with two bedrooms and one bath. The addition to the back of the house has an another bedroom (master), a newer bath with plenty of linen storage, and two large closets.
All four rooms have ceiling fans. The newer master wing has its own heating and cooling unit, which is controlled separately from the rest of the house for greater energy efficiency.
The vintage homes in the Willo Historic District are notoriously shy on closet space and typically have smaller bathrooms. When this house was remodeled it was augmented with extra closets, shelving, an a large bathroom.
