3LHD is an architectural practice focused on integrating various disciplines – architecture, urban planning, landscape, design and art. 

Our office is located in the former Urania cinema.

Despite its age, the building had good predispositions to be adapted, converted and reused.

The new Urania houses public spaces for various cultural events and a couple of office spaces. A multipurpose hall equipped with multimedia and stands is connected to a café bar with a patio and a roof terrace. It is a point of social gathering and public activities, as well as a space for numerous events such as educational workshops, presentations, exhibitions, concerts, screenings and the like.

A unique feature of the Grand Park Hotel Rovinj is its congress / banquet hall, designed to offer a direct view of Rovinj's iconic "postcard" scene — the peninsula with its bell tower. Unlike typical banquet halls, this one is perfectly rotated to showcase this breathtaking view, enhanced by a stunning glass wall that creates a one-of-a-kind visual experience. The design of this feature was a true engineering feat, with collaboration from Sedak to achieve the perfect glass dimensions and bring the vision to life. Red more about this story on the link.

Urania - space of creation, is envisioned as a home for one’s creative expression, especially for the one who questions oneself, society, and the world.

As a space of creation, it considers all of the fields of art and the people who practice it whether they to accomplished or they still have to be so, the ones who are socially aware and the one’s developing audience awareness through education and the exchange of experience.
By interacting and connecting and encouraging education, communication, and innovation as fundamental principles in the process of creative creation, as well as encouraging interdisciplinary work and cooperation with related activities, the development of culture and artistic creation is achieved, connecting the community and activating social change.

Sustainability in our practice

Since the founding of 3LHD, the theme of sustainable construction and environmental care has been present through our earliest projects - whether it's the use of local materials in projects like Sports Hall Bale, introduction of greenery and passive temperature management in projects like the Campus Infobip, the Green Pavilion on the Forestry Faculty Campus, Grand Park Hotel Rovinj, or the exploration and implementation of biodiversity ideas in projects such as the Rimac Campus, Karlovac Freshwater Aquarium and River Museum.
We are committed to advancing sustainability in the context of the built environment, which is manifested through the design of energy-efficient, environmentally friendly, and sustainable architecture. Our office building and cultural space - Urania, is a striking example of the transformation of an existing building with the ability to adapt space for diverse use while reducing emissions, as well as aspects of cultural sustainability by activating users in the city center through the integration of various contents.

3LHD products were created as a response to the needs of specific architecture projects. 

With their aesthetics and function, they emerge from the spaces they were initially created for, but eventually they separate from the project context and become independent products. These products confirm 3LHD's interdisciplinary approach by combining the knowledge of architects, designers and other creators from relevant fields.
