The Mullins House, constructed with wood framing and wood siding, was designed for considerable exterior landscaping. The fence concealed an intimate outdoor courtyard garden, which was flanked by the dining area and living area. Large louvered windows and French doors provided views to and from the garden and gave the back of the house an airy transparency. The first floor also contained a kitchen and large storage room. The second floor contained two bedrooms and two bathrooms. This was the second building--and also the second house--designed by Goldberg.
In Tomorrow's House, Henry Wright and George Nelson wrote "this suburban residence is noteworthy for its plan, interior and exterior design, and details. The plan shows an admirably though out living-dining room, a highly compact service unit, and two bedrooms of generous size. The interiors are consistent and imaginative in their use of materials, and are well related to the all wood exterior. One of the most pleasant and unusual features is the window design which permits the use of sashes up to the ceiling line."
