Koirasaaren Kruunukorttelit
At home in the city, and at sea
Helsinki, a maritime city shaped by centuries of craftsmanship. Continuing this tradition are the Koirasaari Kruunukorttelit, inspired by Jugend architecture. To be completed in summer 2027, Housing Company Helsingin Koirasaaren Kruunuranta offers homes where you can breathe and pause surrounded by sea views.
Koirasaari is located in the eastern part of Helsinki’s city centre, in the Kruunuvuori district. Nearly every apartment opens up to views across the water towards the heart of Helsinki and Suomenlinna.
Alongside the Forma, Flora and Fauna buildings, a fourth building will also be built within the block. This building is not part of the housing company or the apartments offered for sale. It will remain in the ownership of the developer. As the Kruunukorttelit progresses, so too will this website. For now, you’ll find essential information about the project and its current phase.

The apartment reservation process
The apartment page of Koirasaaren Kruunukorttelit will open before the summer holiday season and the process starts with a review. There are 51 unique homes available and we encourage you to take your time when reviewing the floorplans and apartment details. Rservations will be arranged personally with Keele Oy, and apartments cannot be reserved via the website. We will keep you informed about the exact schedule of the reservation opening via our newsletter.
In April we also take a closer look at how the project’s design language flows from the facades into the interiors. The same Jugend-inspired principles are reflected in the proportions, colour choices and small details, creating a coherent whole from the building’s exterior to the home’s finishes.
By registering, you can explore all available apartments and their prices. Registration is free, quick and easy, and does not commit you to anything. You can also contact us by filling the form below or sending an email to info@koirasaarenkruunukorttelit.fi.
