Coretra

What Coretra does

Coretra SA is a Swiss architecture firm founded in 1990 and headquartered in Nyon, Canton de Vaud, with a second office in Geneva operated jointly with partner firm Grenier. Originally established as a technical office for construction monitoring, the firm was acquired in 1997 by Angelo Boscardin, who transformed it into an architecture practice; his brother Flavio joined in 2000. The firm operates under the name Coretra, an acronym for COnstruction, REnovation, TRAnsformation, and delivers a full project lifecycle from initial design studies through key handover. A wholly-owned subsidiary, Coretra Réalisations Sàrl, operates as an Entreprise Totale (general contractor), offering fixed-price construction contracts with after-sales guarantees.

The firm specializes in residential construction, renovation, transformation, and mixed-use developments, with growing activity in horological industrial facilities, public-sector civic buildings (schools, childcare, churches), and administrative centers for industrial clients. Notable technical capabilities include in-house BIM coordination, led by a dedicated BIM coordinator, and demonstrated expertise in Minergie-P and Minergie-ECO high-performance building standards, including the Minergie-ECO 2016 certified administrative center for SADEC SA. The firm employs approximately 30 collaborators across architecture, design, BIM, and construction supervision.

Coretra generates revenue through professional services fees for architectural mandates and through managed services revenue from its Entreprise Totale subsidiary, which contractually takes on fixed-price construction delivery. Pricing is project-based and bespoke, with no public pricing tiers; client acquisition is primarily referral-driven and supplemented by competitive public tenders, particularly for municipal mandates. The firm serves private property developers, individual clients, real estate developers, horological and industrial companies, and public institutions and municipalities, primarily across the Nyon region, broader Canton de Vaud, and Geneva.
