Our current projects are widespread across Europe (United Kingdom, Morocco, Germany, Austria, Croatia, Serbia, Bosnia and Herzegovina, 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.
