At Atellior we understand hospitality and the operation of hotels. We understand luxury and we understand brands. Our wide hospitality experience includes successful interior design and architecture projects with major brands including Four Seasons, Hilton, Kerzner, Marriott, InterContinental Hotel Group, Cheval Collection, Radisson Hotel Group, Hyatt and Accor, to name a few. Our current projects are widespread across Europe (United Kingdom, Germany, Austria, Croatia, Serbia and Montenegro) and range from 5-star luxury resorts, to boutique non-branded hotels which are part of The Leading Hotels of the World, Iconic Luxury Hotels and Small Luxury Hotels of the World.
Each project is approached from scratch, drawing inspiration from current and historical site context. Our ultimate goal is to bear in mind both client requirements and end-user experience throughout our design process.
