Herttoniemi is scheduled for a 4.6 million euro urban and infrastructure upgrade beginning in 2027. The project includes renovating main streets, such as Linnanrakentajantie and Abraham Wetterin tie, with a focus on installing new traffic lights and creating one-way bicycle paths and sidewalks.

In addition to roadworks, the area will undergo residential expansion through the development of hybrid blocks near the Herttoniemi metro station and within the business area. These developments are expected to include housing, offices, and commercial spaces, with some buildings reaching up to 17 stories.
