What Lahdelma & Mahlamäki architects does

Lahdelma & Mahlamäki architects (legal name Arkkitehtitoimisto Lahdelma & Mahlamäki Oy) is a Helsinki-based Finnish architecture firm founded in 1997 by Ilmari Lahdelma and Rainer Mahlamäki, operating with a team of approximately 25 architects, interior architects, competition specialists, and administrative staff. The firm delivers architectural design services across six core product areas: museum and cultural-heritage design (POLIN Museum of the History of Polish Jews, which won European Museum of the Year 2016; Merikeskus Vellamo; the recently opened Lost Shtetl Jewish Museum in Lithuania), educational facilities (Tikkurila Competence Campus, Kirkkonummi Shared Campus, Helsinki Language Upper Secondary School, and design participation in 75 Peruvian Bicentenary Schools), BIM-enabled design and construction services, residential and mixed-use developments (Żurawie block in Gdańsk, Pohjois-Pasila), public service and civic architecture (Kaupunkiympäristötalo for the City of Helsinki, Rauma Main Library), and competition-driven design.

The firm's technical backbone is a centralized Building Information Modeling workflow built on Tekla Structures with Tekla Model Sharing, extended by virtual reality design workshops and augmented-reality visualization on construction sites. This methodology has been recognized with three Tekla BIM Awards (2012, 2017, 2020). Revenue is generated through professional fees on a project basis, sourced via winning open and invited architectural competitions (the primary channel), direct commissions from Finnish municipalities and private developers, life-cycle partnerships with developer SRV that embed the firm in 20-year maintenance contracts, and international consortium participation (the British-Finnish Koulu consortium for Peru) alongside local-firm partnerships (Archiplan in Chile, KXM Group in Poland, Ralph Appelbaum Associates for memorial museums).

Customer concentration is moderate, with a mix of Finnish municipal and government clients, international government clients (Peruvian Ministry of Education), and enterprise developers (SRV, YIT Polska, Kesko). The firm is privately held with no external investment identified and shows no public listing, no subsidiaries, and no recorded M&A, funding rounds, or leadership changes beyond the founding principals.
