Number 2, Willow Road was designed to be both flexible and functional, with a stepped cross-section on the first floor separating the front and back with a step.

The spiral staircase between the levels is both elegant and space-saving, removing the need for large landing spaces.

Movable partitions and folding doors are key to the design on the first floor. The studio can be opened into the Dining Room and Living Room, although it appears that in winter the partitions were kept shut.

Carefully devised colour schemes characterise the surfaces of walls and floors and lend particular moods to each area of the house, influenced by designers such as Le Corbusier, who in turn drew on the work of Cubist painters. As such, the palette of colours grows lighter and brighter progressing upwards through the house.

Texture is also important. Surfaces range from Armstrong tile floors and gloss paint to matt plywood and fine-textured concrete. Photographs from the 1940s show a polar bear fur rug on the Studio platform, adding a note of luxurious softness which also echoed Surrealist themes of juxtaposed opposites. Ledges and recesses are occupied by both objets trouvé and works of art.

Goldfinger also designed much of the furniture and fittings for the property. To preserve the pure lines of its design, the house features built-in cupboards. It also contains tables, desks and chairs by him. He had hoped that his designs might become prototypes for mass production, but British furniture makers proved too conservative and his ideas, including pivoting chairbacks, were not often realised.

Goldfinger's daughter Liz produced a number of furniture designs in the 1960s, examples of which can be seen at Willow Road.
