What | GRENIER + CORETRA | Architecture does

Grenier + Coretra Architecture is a Geneva-based architecture firm founded in 2020 as a partnership between Dominique Grenier and Angelo and Flavio Boscardin of Coretra SA (Nyon). The firm operates with 16 collaborators in Geneva (headquartered at Rue Fendt 2) and has access to a broader 35-person capability pool through its strategic association with Coretra SA. Its core offering is full-service architecture — from initial programmatic sketches through construction management — across residential new builds, energy renovation, sustainable construction, and heritage restoration. The technical profile emphasizes energy-efficient building methods including thermal envelope upgrades, heat pump installations, geothermal heating, photovoltaic systems, grey water reuse, and Minergie/HPE certification compliance.\n\nThe client portfolio is diverse and spans private individuals requiring individual villa work, housing cooperatives including SCHG (136-unit Bâtiment E project) and Halter (Clochettes 20-22-22B energy renovation), real estate developers such as Realitm-Realstone (33-unit La Combaz project in Gland) and StoneEdge Asset Management (Maison Cartier heritage restoration), and governmental/institutional clients including the Kingdom of Thailand (diplomatic mission transformation). Pricing follows standard Swiss architectural fee structures based on project scope, complexity, and surface area, with multi-year contract cadences typical for sizable residential or institutional engagements. The go-to-market motion is direct, relationship-driven sales targeting enterprise and mid-market clients across the Geneva and Vaud cantons.\n\nThe firm operates in a regional Swiss Romande market with no public subsidiaries, no outside investors, no disclosed funding rounds, and no patent or regulatory exclusivity. Distribution relies on the corporate website (grenier-coretra.ch), project portfolio presentation, and direct client referrals within Swiss construction and cooperative networks. Marketing infrastructure consists of website presence supplemented by Google Analytics for traffic analysis, with no public advertising, social media campaigns, or formalized pipeline development programs documented.
