High-quality Living in Espoo
As Oy Seaside is a 15-story residential tower rising next to Accountor Tower in Keilaniemi, Espoo (renovation and alterations by Sarc + Sigge 2020). The building features a total of 83 apartments, ranging in size from approximately 50 to 120 square meters. A 22-story residential tower, As Oy Espoon Skyline, will be constructed on the neighboring plot. Together, the buildings form a functional complex with shared roof terraces and common areas.
Residents will have access to workspaces, a communal area, and a sauna department with terraces opening to the sea and the waterfront promenade. A shared watersport equipment storage will also be located next to the promenade. The apartments offer unobstructed sea and city views, with ground-floor apartments featuring private gardens facing the sea. Upon entering the apartments, one is immediately greeted with views to the outside, often with vistas in two directions.
The residential tower is positioned adjacent to the Keilaniemi waterfront promenade, which is part of the extensive coastal path network in Espoo called ´Rantaraitti´. The promenade and related services will be further developed as the area is built, with plans including a maritime spa.
The building’s architecture is minimalist, with a clean, large-scale design complemented by a rich palette of materials. In its statement, the Urban Planning Committee praised the high-quality architecture of the building, as well as the diverse apartment layouts and well-designed floor plans.
Seaside is part of the reference plan for the Keilaniemi waterfront zoning change, which was developed by Sarc + Sigge in 2018. Next to Seaside, a higher 22-story residential tower has been planned.
Sarc + Sigge is responsible for the main and architectural design of the project.
