What Ateljé Ö does

Ateljé Ö is an award-winning architectural practice headquartered at S:t Hansgatan 38B in Visby on the island of Gotland, Sweden, founded in 2018 by Joel Winsnes and Mats Wahlström Walter. The firm provides full-service architecture spanning concept design, building permit applications, construction drawings, and on-site execution oversight, delivered by a small core team of five architects (plus rotating interns) and supported by academic affiliations at Lund School of Architecture (LTH), SLU Alnarp, and Konstfack Stockholm. Its portfolio covers luxury private residential commissions on Gotland and in the Stockholm archipelago (Villa Butter and Butter Sauna, Nueva Tulle, Djupvike, the Ö17 art collector house), Stockholm hospitality interiors (Gaijin and Bacchanale restaurants), and increasingly public and institutional work, most notably the 2024 international competition win for a new church in Trondheim, Norway.

The practice differentiates through a context-based design philosophy that treats architecture as fine art and emphasizes integration with Gotlandic landscapes, hand-crafted detailing, and direct collaboration with builders and craftsmen across the full project lifecycle. In 2023 the firm extended its brand with KAADA, an art gallery at Döbelnsgatan 8 in Stockholm, and its ongoing work-in-progress is documented via a portfolio website, Instagram (@atelje_o), and academic lectures at Porto Academy, Konstfack, and Lund.

The business model is professional services: project-based commissions quoted individually for each brief, with no publicly disclosed pricing and no recurring or subscription revenue. Projects are acquired primarily through architectural competition wins and direct commissions from private clients, restaurants, and cultural institutions, with marketing driven by portfolio, awards, and academic visibility rather than paid distribution. Ateljé Ö is privately held by its founding partners and team, with no disclosed external investors, venture capital, or private equity involvement.
