The character and typology of the housing was preserved, even where space was divided. As far as possible, all of the rooms, large or small, have retained a simple décor, including plaster ceilings with cornices and decorative plasterwork, false panels, fireplaces, parquet and terracotta floors.  

To make the housing more comfortable and in line with modern living standards, the kitchens and bathrooms were upgraded and transferred to the existing service and clearance areas, which have been opened up to provide more natural light.

The workshop mezzanines originally gave the artists additional space and allowed them to have a functioning area below, including an entrance, a small living area and their own toilet. Over the years, this layout has changed: the mezzanines were extended, divided or closed. It seemed necessary to rethink the layout by opening up, reducing and restoring the original character of the mezzanines which give onto the workshops, and by allowing natural light, which is a feature of these rooms, back in.    

The few original mezzanines were restored, while a contemporary approach was used for the new ones (including perforated metal) in compliance with current safety standards.
