What 21spaces does

21Spaces Design Limited is a Dublin-headquartered, multi-disciplinary interior architecture and design consultancy operating across the hospitality, multi-residential, retail, and workplace sectors. Founded in 2005 and registered in Ireland as a private limited company (company no. 392467), the firm provides end-to-end services spanning site analysis, design concept and detail development, planning and fire certificate applications, project management, health and safety supervision, and brand creation. The firm maintains a secondary office in London to support international delivery and has documented project work across Ireland, the UK, UAE, Pakistan, Bangladesh, Saudi Arabia, and New Zealand.

The company generates revenue through project-based professional services fees, with each engagement individually scoped and priced. Its go-to-market is direct enterprise engagement with hotel groups, build-to-rent (BTR) developers, retail chains, and commercial property operators, relying on reputation, repeat business, and industry relationships rather than intermediated distribution or paid marketing. Named enterprise clients include O'Callaghan Hotels, Greystar, Glandore, Butlers Chocolate Cafe, Musgrave, Lioncor, Dunnes Stores, Croke Park, and the Guinness Storehouse, with the firm holding multiple industry recognitions including the 2017 Fashion Store of the Year and a 2017 Echo Chamber Top 10 Global Retail Stores listing.

21spaces is privately held with no disclosed external funding, parent entity, or institutional investors. The firm is a member of the Irish Design Institute (IDI) and holds no patents or technology IP; its core assets are creative talent, long-standing client relationships, and a documented award-winning portfolio spanning protected structure conversions, Georgian building transformations, and large-scale BTR scheme amenity design.
