A single-family home (year of construction about 1928) which has undergone several alterations without improving upon it, was to be converted into a two-family home. The entire attic was demolished and an upper storey with a gallery in the attic space was set up new. Exterior walls were bricked up, whereas the gallery storey and roof construction were executed in timber. The existing balcony in the upper storey was built over by a glass house.
