What Baubureau OG 27 AG does

Baubureau OG 27 AG is a Swiss architecture firm founded in 2013 and headquartered in Trimmis, Canton of Graubünden, with a secondary office in St. Moritz serving the upper Engadin region. The firm provides full-service architectural design, working drawings (Werkplanung), construction management, and project supervision for residential, commercial, and municipal projects, with stated specialization in renovation, conversion of existing buildings (including pre-1990 structures requiring hazardous material remediation), and new construction in Alpine contexts. Its team of approximately 20 professionals, led by owner Lorenzo Lazzarini (dipl. Techniker HF Bauplanung), includes architects, federally certified construction managers, draftspersons, an apprentice cohort, and administration; sister firm OG Real Estate AG (owned by Pia Crufer) operates alongside it under the OG Gruppe umbrella.

The firm's service stack extends beyond conventional architecture into hazardous material diagnostics (Schadstoffbeprobung), specialist abatement construction management (Fachbauleitung Schadstoffsanierung), post-remediation indoor air quality measurements (Raumluftmessungen), and waste disposal planning aligned with Swiss VVEA Article 16. Revenue is generated through project-based professional services fees for private homeowners, property developers, municipalities, and hospitality/commercial clients (restaurants, brasseries). Customer acquisition is direct and sales-led, relying on relationships, referrals, a comprehensive website portfolio, and organic social channels (Instagram, Facebook). Geographic reach is concentrated in Graubünden — covering Chur, Trimmis, St. Moritz, Davos, Arosa, Lenzerheide, Samedan, Pontresina, and other Engadin villages — with no disclosed operations outside Switzerland. Pricing is not publicly disclosed and is set on a project-specific basis.
