The built-in furniture determines the interior to a great extent. Twelve cabinets are preserved. Almost all of them are in Oregon pine, which is varnished to make it look like mahogany. The panels of the doors are made of plywood, the other parts are massive. Typical for Eysselinck is a shelf with two kinks in it; so it consists of a horizontal part, followed by a vertical part and a lower horizontal part. This design can be seen in the chest of drawers in the study. It is constructed in elements in concrete and covered with plywood.
