The main entrance to Fredensborgveien 103 is emphasized by the lobby protruding from the building's main body. This is further underlined by the yellow horizontal cladding being extended down to the ground floor. This effect was much used on functionalist/early Norwegian modernist wooden houses. On the roof of the lobby is a balcony used for airing clothes and bedding.

The villa was built for Jan Brochmann Halvorsen, a bank manager, and when the saving bank's building burnt down in 1940, the bank moved into the villa for the rest of the war years.
