Lab 3 Architekci

What Lab 3 Architekci does

Lab 3 Architekci is a Poznań-based architectural practice founded in 2017 as a Polish limited liability company (sp. z o.o.) by Dominik Banaszak and Marcin Mleczak. The firm delivers architectural and urban design services across residential, office, commercial, public, and industrial building types for a diversified client base that includes real estate developers, municipal and government entities, industrial and manufacturing companies, and private individuals. Documented enterprise clients include Solaris Bus & Coach (bus manufacturing), Geberit (sanitary products), Galeria Wola Park (retail — Klépierre), Bouygues Immobilier Polska, BUDIMEX Nieruchomości, Novaform Polska, ARD, and Boekestijn Real Estate.

The practice operates a project-based professional services model, generating revenue through architectural competition wins and direct commissions, with billing tied to project milestones rather than recurring contracts. Its technical stack centres on industry-standard CAD and BIM tools rather than proprietary technology, and its competitive positioning rests on the founders' 12–20 years of industry experience, BIM expertise, and a portfolio of competition credentials recognised by SARP and IARP. The firm has a headcount of 14–30 and share capital of 60,000 PLN.

Geographic expansion to date is limited but visible: the practice won an international competition to design bus stops in Stavanger, Norway — its first documented cross-border engagement. It has also pursued consortium-based delivery, partnering with AiG Architekci and Arte Monoblok Architekci on the Rokietnica project. The April 2026 death of co-founder Marcin Mleczak is a material continuity event for a boutique, founder-led practice of this size.
