LUMIA

What LUMIA does

LUMIA is a Tallinn-based architecture and interior design studio specializing in modern contextual architecture, heritage restoration, sustainable construction, and exhibition/spatial design. Founded in 2021 by Margit Aule and Toomas Adrikorn as a successor to KAOS Arhitektid (founded 2010), the firm began operations in early 2022 and today consists of approximately 9–12 architects and interior architects, several of whom hold chartered/diploma level-7 certifications. The firm serves three primary customer segments: public sector institutions (schools, libraries, museums, government buildings, embassies), real estate developers (commercial, residential, and mixed-use), and heritage property owners (castles, churches, manor houses, protected monuments). Notable technical capabilities include cross-laminated timber (CLT) high-rise construction — demonstrated on Estonia's first fully timber-constructed 8-storey office building (Tartu mnt 84b) in collaboration with ETH Zürich and Tallinn University of Technology — and heritage restoration that integrates contemporary elements such as steel domes and glass partitions into historical monuments.

The firm has delivered a portfolio of 50+ projects including the Fahle Park development with Fausto Capital (which achieved the first BREEAM Outstanding certification in Estonia and the Baltic states), award-winning restorations of Kuressaare Episcopal Castle and Põltsamaa Castle, the Estonian Embassy in Moscow, and the Estonian Consulate General in San Francisco. LUMIA's revenue model is professional services fees for architectural and interior architecture design, with project acquisition driven primarily by winning architectural competitions (the firm has accumulated numerous first-place national and international awards, including the Estonian Cultural Endowment Grand Prize, European Museum of the Year Award special commendation, and EU Mies van der Rohe Award nominations) and by repeat commissioned relationships, most notably with developer Fausto Capital. The firm holds an Estonian heritage conservation activity licence (EMU000592), operates with a partner consortium of structural engineers (studio ARGUS), landscape architects (KINO maastikuarhitektid), and creative/exhibition designers (PULT), and is privately held with concentrated ownership among its founding partners and no disclosed institutional investment.

Direct peers

• Arhitekt Martin Aunin: Tallinn-based Estonian architecture office working across cultural, public, and contextual-architecture briefs. Comparable as a same-city peer competing for Estonian heritage, museum, and cultural-institution commissions similar to those won by LUMIA.
• 3+1 Architects: Estonian architecture practice with a portfolio spanning residential, public, and commercial buildings in Tallinn. Comparable to LUMIA in scale, location, and the type of competition-driven Estonian briefs both firms pursue.
• Salto Architects: Tallinn-based architecture practice of broadly similar scale focused on contemporary contextual architecture and urban interventions in Estonia. Highly comparable as a same-city, same-segment local competitor bidding into the same competition and heritage briefs that LUMIA pursues.
• Kadarik Tüür Arhitektid: One of Estonia's largest and longest-established architecture studios, headquartered in Tallinn. Comparable as a direct domestic competitor across both new-build commercial/residential work and heritage-adjacent public commissions.

Broad incumbents

• Zaha Hadid Architects: London-based global architecture firm recognized for contemporary contextual buildings, museums, and cultural institutions, alongside heritage-adjacent work. Comparable at the level of brand-led, award-driven cultural and public-architecture commissions similar to those LUMIA delivers (e.g., castles, museums, embassies).
• Snøhetta: Norwegian-founded global architecture practice renowned for sustainability-led and contextual design (e.g., timber and landscape-integrated buildings). Comparable as a much larger, globally established practitioner whose sustainability, heritage-integration, and cultural-institution portfolio sits in the same architectural category as LUMIA's premium Estonian commissions.
• BIG (Bjarke Ingels Group): Copenhagen-headquartered global architecture practice with a strong sustainability and mass-timber/high-rise track record. Comparable as a Nordic incumbent whose CLT/mixed-use and cultural portfolio overlaps thematically with LUMIA's mass-timber (Tartu mnt 84b) and heritage-adaptive reuse work.
• Foster + Partners: Global architecture and integrated design practice with a portfolio spanning sustainable commercial towers, cultural institutions, and heritage-sensitive projects worldwide. Comparable as a broad incumbent whose mix of high-rise sustainability and cultural/heritage work covers the same architectural segments LUMIA serves.

Others

• Nordecon: Major Estonian construction and real-estate group headquartered in Tallinn, active as both contractor and developer on many of the same public and commercial builds in Estonia. Comparable as the commissioning/builder counterparty to LUMIA's design commissions rather than a competitor; useful as a reference for Estonian construction market scale and cycles.

Regional players

• Henning Larsen: Copenhagen-based architecture studio with deep Nordic expertise in sustainable, contextual buildings and cultural projects. Comparable as a regional peer in the Nordic/Baltic design culture whose sustainability and public-sector typologies overlap with LUMIA's sustainability-and-heritage positioning.
