The chrome-plated address plaque for the residence of Albertus H. Sonneveld at Jongkindstraat 12, Rotterdam [with the Het Nieuwe Instituut of architecture and design now located just down the street]
A W.H. GISPEN ceiling lamp in the master bedroom, with the newly developed GISO milky glass shade to reduce glare and diffuse the light. The whole house was furnished almost exclusively with the Dutch designer's tubular steel furniture and lighting innovations.
Elegantly designed SATCHWELL thermostats, one for daytime and the other for nighttime control. [The Satchwell manufacturing company had just been established in the U.K. in the early 1920's and is now based in South Africa.]
Wall clocks of the most minimalist design were installed in many of the rooms and connected to the electrical circuits for each room, which was still a novel feat for the 1930's!
A sweetly printed sign to instruct the deliverymen to leave their orders beneath and to "adopt" nothing!
