The interior is divided into two areas. A social area includes a living and dining room, and a balcony, while the bedrooms are located in the private area.
Different materials and finishes are used to draw a distinction between the spaces. Basalt covers the flooring in the main living area.
Ceilings and walls within the space are lined in a slatted Freijó wood panelling that was also used to conceal doorways. a custom-built cabinet that attaches to the wall below the television is also made from Freijó wood.
