What Arhitektuuribüroo Korrus does

Arhitektuuribüroo Korrus OÜ (trading as AB KORRUS) is an Estonian architectural and construction design firm headquartered at Järvevana tee 7b, Tallinn, and operating for approximately 20 years. The firm delivers architectural and construction design, construction consulting, construction project management, and construction and author supervision services across the full spectrum of building typologies — single-family homes, semi-detached and row houses, apartment buildings, commercial buildings, public buildings, and interior design. Its core technology stack consists of industry-standard CAD and 3D visualization software; no proprietary platforms or AI capabilities are indicated.

AB KORRUS serves four primary customer segments: private homeowners, residential real estate developers, commercial property developers, and (secondarily) public-sector clients such as municipalities. Engagement is project-based and quote-driven, with pricing determined per project scope rather than under recurring contracts. Marketing and distribution are deliberately lean — the firm relies on its project portfolio website, professional photography, and direct inquiry through a contact form, phone, and email. No public-sector framework agreements, recurring SaaS contracts, or enterprise procurement relationships are indicated. Documented working relationships include Estonian developers Kaamos Group and Domus Kinnisvara, and collaborating peer firms including KOKO Arhitektid and Arhitektid 11.

The company is privately held as an Estonian OÜ (private limited company) with no disclosed parent, subsidiaries, funding rounds, or institutional investors. Operations are concentrated in Estonia, with secondary activity noted in Latvia. No revenue, headcount, awards, patents, or management-team information are publicly disclosed; the firm operates without app, API, or SDK products and has no stated AI/ML capabilities.

Direct peers

• Salto Architects: Tallinn-based Estonian architectural firm with comparable multi-typology practice spanning residential, public, and interior design. Most direct local peer given similar Estonian-market focus, design-led approach, and project-based fee model.
• HG Arhitektuur: Estonian architecture practice offering comparable residential, commercial, and public-building design services in the same local market. Similar scale and project-based delivery model make it a directly comparable peer for competitive benchmarking.
• KAMP Arhitektid: Estonian architectural firm with comparable portfolio across residential, public, and commercial typologies. Directly comparable in scale, Estonian market focus, and project-based professional services delivery.
• 3+1 Architects: Estonian architecture practice active in residential and public-sector projects within the same geographic market. Comparable boutique scale and multi-typology project portfolio make it a directly relevant peer.
• Arhitektid 11: Estonian architecture firm already collaborating with AB KORRUS on the Telliskivi tn 49 accommodation project. Operates in the same multi-disciplinary architectural services space with comparable typology coverage.
• KOKO Arhitektid: Estonian architectural firm already collaborating with AB KORRUS on projects such as the Rakvere Reketlonihall. Operates in the same Tallinn-based, multi-typology architectural services market with overlapping developer and public-sector clients.

Regional players

• ALA Architects: Nordic (Finnish) architectural firm with strong portfolio in cultural, public, and residential buildings across the Baltic/Nordic region. Comparable in typology breadth and serves as a regional benchmark for design quality and project scale.
• LUW Architekts: Latvian architecture firm with comparable multi-typology residential, commercial, and public-building practice. Functions as a regional peer given AB KORRUS's emerging cross-Baltic exposure into Latvia.

Broad incumbents

• Foster + Partners: Global architecture and integrated design firm offering services across architecture, interior design, and project management — a broad incumbent in the same professional services category, though operating at materially larger scale and typology reach.
• Zaha Hadid Architects: International architecture firm with recognized brand in commercial, cultural, and residential design. Operates as a broad incumbent benchmark for design-led positioning, though not in direct competition for AB KORRUS's mid-sized Estonian project mix.
