Based on an analysis of the existing apartment, a prioritised list of measures was drawn up together with the client: new floor coverings, plastering and painting throughout the apartment, refreshed doors, and adjustments to the electrics, kitchen appliances and plumbing. The kitchen and bathroom were made homely with small, inexpensive interventions so that they can be lived in comfortably; their refurbishment will follow as a later stage.

Quotations were obtained for the trades and compared in a price comparison table; negotiations during the contract award led to savings. The planning-law situation was clarified with the municipality, so the work could be carried out without a building permit application.

A special feature of the project: the client took on the site management themselves. Studio Wirz introduced them to the task, enabled them to carry out the works independently and provided advice during construction.
