Glenn Sestig Architects

What Glenn Sestig Architects does

Glenn Sestig Architects is a privately held, eponymous architectural and interior design practice founded in 1997 by Glenn Sestig in Ghent, Belgium. The firm provides full-service architecture, interior design, and project management across residential, commercial, cultural, and hospitality sectors, with a stated emphasis on minimalist, modernist spatial design, material honesty, and subtle spatial luxury. Core offerings span contemporary architecture, heritage reconversion, residential interiors, retail, hospitality venues, art galleries, corporate spaces, and temporary installations, alongside an extensive product-series portfolio of co-designed furniture, lighting, bathroom, hardware, and kitchen collections with European luxury manufacturers including Giobagnara, Obumex, CEA Design, Vervloet, Ozone Paris, Ormond Editions, Kvadrat/Cassina, 100% Light, and Lison De Caunes. The firm also operates La Réserve Resort, a five-star superior hotel in Knokke, Belgium, encompassing hotel, wellness, restaurant, bar, private salons, and wine cellar.

The firm serves a narrow, high-end clientele anchored by leading fashion designers (Raf Simons, Pieter Mulier, Ann Demeulemeester, Olivier Theyskens), visual artists (Luc Tuymans, Louis Lannoo), musicians (Soulwax/2ManyDJs), real estate developers (Versluys Group, MG Real Estate), and luxury hospitality operators. Projects are commissioned directly through reputation, creative-industry networks, and earned media in publications such as Wallpaper*, Vogue, Elle Decor, Harper's Bazaar, AD, and Ark Journal, with the studio also maintaining presence at Milan Design Week and Design Biennale Interieur Kortrijk. Revenue is generated through professional fees for architecture and interior design services on a project-by-project basis and, increasingly, through royalties and co-design IP from the product-series collaborations; pricing is not publicly disclosed.

The practice is small — approximately 10 staff including founder and head architect Glenn Sestig, creative director Bernard Tournemenne, project and operational manager Tim Malfait, and personal assistant Julie De Rouck — and is currently recruiting additional architects, indicating capacity expansion against demand. The studio operates from Pavilion Sestig in Deurle, Belgium, a 1970s modernist pavilion originally designed by Ivan Van Mossevelde that doubles as the founder's residence and as a curated showroom, and undertakes projects across Belgium, France, the UK, Italy, Switzerland, Monaco, China, Japan, and the United States. Recognition includes Architizer A+ Awards and Archiproducts Design Awards in 2023, and prior Architizer and WIN Awards in 2014.
