Indoor B.V. was at least active since the beginning of the 60’s. Mister Cohen was the president. They had their offices and expedition at the Sloterkade street and a shop at the famous Paulus Potterstraat 22-24 in Amsterdam in front of the Van Gogh museum.

Also an art gallery was located at the same address. It was named Galerie Inart and opened in 1969. The gallery was an initiative of Indoor. Carla Koch managed the gallery. In 1996 she opened her own gallery, specialised in ceramics under the name Galerie Carla Koch.

Famous Finnish designer Kaj Franck opened a permanent “workshop” in the Indoor shop about his well known Arabia glass and ceramics in 1983. Indoor was the importer of Arabia for the Benelux (Belgium, The Netherlands, Luxembourg).

Indoor B.V. also had a company in Belgium, it was named Indoor Pvba. It had a showroom in Brussels at the Steenweg op Charleroi 137.

Indoor imported modern lighting, glass and ceramics mainly from Scandinavia. The company sold also lamps from other companies such as the Italian Stilnovo, Arteluce and Stilux and the German Staff.
