What Grand & Johnson does

Grand & Johnson is an Amsterdam-based interior and product design studio founded in 2002 by Bertel Grote, operating as a private, founder-owned firm with an intimate team of interior architects. The studio specializes in large-scale renovation and new-build projects for luxury private residences (villas, penthouses, canal houses, country estates and second homes) and commercial clients (corporate headquarters, retail, healthcare, and multi-unit residential developments), with a project footprint spanning the Netherlands and international locations including Mallorca, Bonaire, Dubai, and references to Southern France and Portugal. The service offering is full-service, from initial sketch and concept through schematic, preliminary, and definitive design to execution supervision and handover, with a free initial consultation and a kick-off session as entry points and bespoke multi-year engagements as the core delivery model.

The studio uses VectorWorks and SketchUp as its core design and visualization tools, with 3D photorealistic rendering as a central client-presentation and construction-guidance mechanism. AI integration is being explored but not yet a core capability. Beyond interior architecture, Grand & Johnson maintains a product design portfolio of proprietary designs (Shiraat door handle, SOHO bathroom collection, Bō lighting, Dandy rug, and a GJ furniture line) licensed to manufacturers including Intersteel, JEE-O, Maretti, Grey-7, and Carpetlinq. The studio generates revenue from professional design fees on bespoke projects and from licensing royalties on its product designs, with historic reliance on word-of-mouth referrals (~90% of projects) and growing use of earned media, blog content, email newsletters, a downloadable Lookbook, and webinars as additional acquisition channels. Notable industry recognition includes two Red Dot Awards (2014 SOHO shower, 2022 Shiraat door handle), regular features in Dutch and international design publications, listing among the top 10 Dutch interior designers, and BNO membership; the studio relocated from Tramremise De Hallen to the BREEAM Outstanding-certified 'De Jonas' building in IJburg harbor in 2024.
