Strättligen Housing Estate Renovation

Renovering til opprinnelig design

The Strättligen housing estate, located in Dürrenast, Thun, was originally built in 1965 and consists of eight buildings that range from three to six storeys. The estate includes 138 rental apartments and is currently in residential zone 3. The main objective of the renovation is to restore the architectural appearance to its original design from the 1960s, correcting changes made in the 1980s.

Tre etapper, kort tidsramme

The renovation project is divided into three stages and includes extensive work on the façade, kitchens, bathrooms, and lobby areas. One of the main challenges is that the renovations will be carried out while the apartments are occupied, necessitating careful modernization of utility lines and complex pollutant decontamination. Despite these challenges, the project was successfully launched, advertised, and awarded within an extremely short timeframe of just five weeks.
