Kotka’s new UNESCO site sparks immediate interest in housing and event tickets

The Sunila residential area in Kotka was added to the UNESCO World Heritage List last weekend, and the decision has already boosted interest in the area.

Local real estate agent Jani Kylmänen reports a rise in inquiries about apartments, with some viewings already conducted. Ticket sales for the August Aalto event have also surged, according to Yle.

Designed by architects Alvar and Aino Aalto, the Sunila area was built between 1938 and 1954 and currently houses around 1,100 residents. Apartments in the architecturally significant district have sold for as little as €20,000.

Kylmänen notes that while sellers may expect prices to rise following the UNESCO listing, immediate increases are unlikely. Upcoming renovations in the housing cooperatives will also factor into buyers’ calculations.

Interest in Sunila has long been driven by its architecture and affordability, attracting buyers—often from the Helsinki region—seeking second homes. Current demand is strongest for one- and two-bedroom units priced under €40,000.

The Aalto Homes event, organized by Pro Sunila, will open around 20 Aalto-designed homes to the public on August 29–30. Event producer Noora Kiili says the UNESCO announcement triggered a sharp spike in ticket sales, with nearly half already sold. Previous years saw sell-outs, but typically only in the final weeks before the event. This year, organizers increased capacity to up to 2,000 tickets in anticipation of higher demand.
