Kestävän kehityksen ratkaisut:
The solution’s key circular component is revitalising a community through the extension of an older building’s lifecycle, while turning perceived weaknesses into strengths. For example, the limited space of some residential units has been turned into an attractive feature, as this encourages sharing economy practices among the residents.

As the lifespan of existing buildings is extended, there is reduced waste compared to complete demolition and new construction. Inside the rooms, eco-friendly materials from local suppliers are utilised. The encouragement of circular living also has a positive environmental impact, such as reduced use of cars due to limited parking space.

As a result of this first project, the company has signed a circular economy agreement with the city of Zama to improve the circular economy in the local community by increasing the efficiency of waste management and conducting awareness raising campaigns.
