Tammisto Electricity Substation
The Tammisto Electricity Substation is situated in a crucial hub for power transmission in the Helsinki region. The existing facility includes several buildings and structures, each with unique characteristics. The oldest and most iconic building is the Aarne Ervi-designed former substation, built in 1947. The architectural goal of the new project was a harmonious visual language for the site’s existing and new structures.
The design features a two-story layout with reddish water-struck bricks to blend with the historic substation and a nearby residential area. Umbra treatment turned old transformer bunkers to earthy tones. New landscaping seeks to improve the aesthetic quality of the environment and helps with rainwater runoff management. Natural light inside contributes to a beneficial working environment.
