The gentleman's dressing room is reached from the bedroom. Its furnishings and the wooden panelling on the walls were created by the architect Jan Vaněk for S.B.S. Brno. Adolf Loos was glad to collaborate with this firm because its level of craftsmanship guaranteed that the fittings made were perfectly suited to their function. Jan Vaněk was a specialist in the design and manufacture of storage spaces of all kinds.
The furniture and panelling in the dressing room are made of oak, and the closet insides have a mahogany veneer. To create interesting colour and structure in the furniture surfaces, Vaněk used oakwood veneers. To the left of the entrance are wardrobes with sliding doors; they have shelves inside and chrome metal pegs for storing shoes. To the right of the entrance along the wall is a hanging closet with chrome metal coat hangers and sliding shelves of the English type for keeping clothes. On the inside of the door is a large mirror. The settee, toiletry table beneath the window and Windsor chair did not survive - those displayed are reconstructions.
During the reconstruction the original fittings were professionally cleaned and restored to let the beauty of the woods used shine through.
