Seaside development site in Karhusaari, Helsinki, Helsinki

Exceptional development site in Karhusaari – tender sale, maritime location and significant development potential!

Welcome to Karhusaari, a hidden gem of Helsinki, combining a unique maritime setting with a rarely offered development opportunity. This property is being sold by tender and presents an outstanding chance for a private builder as well as, in particular, a construction company or developer.

For sale is a parcel to be separated at completion of sale from a larger plot into an approximately 2,000 m² lot. There is already a deviation permit in place for one detached house on the proposed lot, and under the new plan the building-rights potential is significant: the lot can be subdivided into separate smaller lots of at least 500 m² each. Once the plan is confirmed it would be possible to realise several detached houses, semi‑detached houses or even a terraced housing complex. Such development sites are very rarely available in the Helsinki area.

The Karhusaari location is exceptional – maritime, peaceful and prestigious. The surroundings provide superb conditions for high‑quality living, making the site especially attractive from the perspective of demand for finished homes.

The property also has a ready-designed concept that allows construction of a detached house. If desired, you can use the existing plans or develop the plot more broadly in line with the opportunities offered by the new plan. The plan forms part of Helsinki’s Karhusaari northern area zoning amendment no. 12818 and, according to the planner, the revised proposal is progressing to the Urban Environment Committee in spring 2026.

The area combines tranquillity with Helsinki’s services: nearby you will find schools, day nurseries and basic services, and transport connections to the city centre are convenient. The maritime environment, greenery and calmness make this location particularly sought after.

This is a site that combines: - Rare location in Helsinki - Significant development potential - Flexible implementation for both private and professional builders - Tender sale, allowing the market to determine value

Such development opportunities come to market infrequently – now is the right time to seize the opportunity.

The plan forms part of Helsinki’s Karhusaari northern area zoning amendment no. 12818.
