The discussion started with a critical question: what do you mean by sustainability? How do you create more homes without destroying the old ones? Is such a large population in Sibbesborg area sustainable?

The online audience asked, could Sibbesborg learn something from the process of how Tapiola was born. There seems to be a perfect balance of cars and pedestrians in Tapiola, so should we make a new garden city? Opposing views were also mentioned as Tapiola was seen as a social desert. Should it become a role model for Sibbesborg or not? One commentator was very critical of should Sibbesborg even be located in Sipoo at all. Maybe it would be more sustainable to build it in Vantaa, Helsinki or Espoo?
