Bokšto Skveras is a mixed-use quarter in Vilnius that has revitalized a dilapidated UNESCO world heritage site with a creative and contemporary approach to restoration. The project includes six historic buildings and courtyards, including the former Savi?ius Hospital and St Elizabeth Chapel. After extensive archaeological investigations and research, the restoration balanced the retention of original baroque architecture with modern design elements. The resulting site includes a variety of functions, such as apartments, a spa, and a restaurant, with minimal contemporary additions that respectfully connect with the heritage structures. The most notable architectural intervention is the innovative construction of steel slats for the roofs, which maintains the original roof form while allowing for light-filled roof accommodation. Environmental sustainability was also a priority, achieved through the application of passive solutions and improved building materials. Overall, the project is a testament to the vision, passion, and contextual understanding of the designers, and sets a benchmark for cultured responses to heritage buildings.
