The challenge was to design a modern and sophisticated five-star hotel in the historic coastal city on the Croatian peninsula of Istria. The design needed to adapt to the local culture and incorporate both summer and winter seasonal elements as well as sustainable design features. Set into the hillside, the 109-room hotel with ten luxury suites is spread over four levels and boasts a dramatic panoramic glass wall that greets guests with an uninterrupted view of the sea. Bars, lounges and restaurants are located on lower levels, with spacious terraced areas for fine dining and relaxation on warm days. A traditionally-styled wine vault is located at the lowest level. Because a nature reserve is situated across the bay from the hotel, and the hotel itself is set within the city on a main promenade, both urban and natural elements were part of the design. Great care was taken to take advantage of natural light, including studies of light and shade on the windows throughout the year. The curved roof is positioned so that the glazed wall is in shadow during the summer, minimizing heat gain and the need for air conditioning.
