About Keiko Ark Studio

Keiko ARK is an architecture practice based in Helsinki. Its main services are housing and special-needs housing design, covering new buildings, renovations and urban infill (täydennysrakentaminen). It also provides restoration design for historical and heritage sites and building-history research.

For private clients, the practice offers services as needed, from concept design through the building permit process to implementation design. The firm is a member of the Finnish Association of Architects (ATL) and of Tilaajavastuu.fi.

Keiko ARK was founded in 1984 and continues the work of Arkkitehtitoimisto Koskinen & Schalin Oy, which operated from 1988 and was run by founders Keijo Koskinen and Christel Schalin. The transition to the new name took place through a generational handover.

Product: Architectural design services for housing, special-needs housing, urban infill, heritage restoration and building permit processes.
