Step away from traditional West End stereotypes into this magnificent and historic, Mediterranean style 2 story home. Originally the Dr. Wilhelmy Estate, this property was later owned by an interior designer and the attention to detail is evident throughout. Marble flooring, unique art glass windows, detailed ceilings, walnut woodwork, cedar lined closet, updated bathrooms and kitchens, a newer roof with commercial gutters and downspouts . .. are all components that set this house apart. The partially finished basement offers many options for recreational activities or additional living space or more and more storage. If you are interested in a West End home, this one is a Must See! Selling As Is.
