Sarc + Sigge

What Sarc + Sigge does

Sarc + Sigge (legal entity: Sarc + Sigge Arkkitehdit Oy, business ID 0799078-0) is a privately held Finnish architectural design practice headquartered in Helsinki with a secondary studio in Turku. The firm was formed in February 2024 through the merger of two multigenerational practices — Sigge (founded 1956) and Sarc (founded 1965) — and consolidated into a single legal entity on 31 December 2024. It employs approximately 120 architecture professionals and is partner-controlled, with Pekka Mäki as CEO since April 2025 and Sarlotta Narjus as Board Chair from December 2025.

The firm delivers professional architectural design services spanning new construction and renovation/adaptive reuse across seven explicit service categories: Architecture (core), High Rise Design, Sustainable & Lifecycle Design, Renovation & Reuse, Urbanity & Landscape, Interiors & Workplace, and BIM & Digitalisation. Its core technology stack is BIM-based digital design integrated with lifecycle/sustainability methodology and circular-economy construction principles; no proprietary AI/ML or software products are disclosed. The firm's international claim-to-fame rests on the Finnish Embassy in Berlin ('Best building in the world', Arup World Architecture Awards 2001) and the New Children's Hospital in Helsinki (Finlandia Prize for Architecture, 2018).

Revenue is generated through project-based architectural fees on direct enterprise and public-sector commissions, secured via competitive design competitions and negotiated contracts. GTM motion is partner-led, with nine named partners active in business development. Customer mix spans healthcare (HUS Helsinki University Hospital, New Children's Hospital), education (Aalto University, Turku University of Applied Sciences, Åbo Akademi), commercial real estate (Ahlström Capital, YIT Rakennus, HGR Property Partners), government (City of Tampere, Ministry for Foreign Affairs), and hospitality (Jumeirah Group, AVIA Real Estate), anchored by multiple LEED Platinum and BREEAM-certified deliveries across Finland and selected international projects in Dubai (Burj Al Arab Terrace) and Berlin.
