Solvallastaden is a new urban development area where Stockholms Travsällskap and the city of Stockholm intend to build 1,700–2,200 apartments along with pre-schools, school and commercial premises. Balder will now begin the work with the zooning plan, which is expected to be completed in 2021. The same year as the new commuter train station will connect to the area.

"We are proud to have gained confidence from Stockholms Travsällskap to be a part of the realisation of Solvallastaden. Our ambition is that this will become one of the most exciting districts throughout the region," says Erik Selin, CEO of Balder.
