We care about the environment

We want to move the property and construction industry towards carbon neutrality together with our clients and other operators in the industry. Our goal is for our own operations to be carbon neutral by 2035. However, we recognise that our real chance to influence the sustainability of the property and construction industry is through the properties we design.

We meet the challenges of the future by increasing our designers’ expertise in designing sustainable and low-carbon environments. We are part of the Finnish Green Building Council, and we are also supporters of the #BuildingLife action plan.

The well-being of the planet is important to us, which is why we always strive to design as sustainably and ethically as possible.
