In the popular retail area of Tammisto in Vantaa, the Tammistonportti retail project was developed. The third phase increased the total surface area of the building to over 11,000 sqm.
The building was constructed with a wooden frame and steel-plated walls. The type and style of the structures and façade are in keeping with earlier construction phases. The last phase of this project was designed to serve demand in the area for construction and interior design retail.
