Sepapaja 6 is a beautiful two-storey limestone building listed in the National Register of Cultural Monuments as an architectural heritage site. The building is estimated to have been constructed in 1899. It originally served as the central chemistry laboratory of the former Dvigatel factory, with a doctor’s office located on the second floor.

In 2006, the building was renovated into a modern office facility and today bears the name of Artur Lind – the founder of molecular biology in Estonia and a respected academician.

Named after Alma Tomingas, the first Estonian female professor and pharmacist, this green building stands out with its architecturally dynamic design, spacious layout and intriguing spatial solutions that pay tribute to engineering excellence while creating a naturally light-filled environment.

The 11-storey landmark features distinctive design elements, offices with panoramic views of the airport and Lake Ülemiste and an open, flexible floor plan. On the ground floor, there is a breakfast and lunch restaurant, while a lush tropical atrium garden weaves its way through four floors.

The building has been awarded the LEED Gold green building certification.

Ülemiste City Health Centre 1 is located in the heart of the campus, next to the historic Dvigatel factory park and apple orchard. The building brings together top specialists from various fields of healthcare with long-standing experience, offering high-quality and evidence-based specialist and primary care services. The quality of care is ensured through a client-centered approach and the use of smart solutions that focus on both disease prevention and improving quality of life.

The building also features a green rooftop terrace where visitors can relax and enjoy the fresh air.

Health and wellbeing are key priorities for Ülemiste City, along with creating an environment that supports them. The development of the second Health Centre has been guided by the 3×3 Health Model developed by the University of Tartu, which forms the basis for supporting the mental, physical and social health of talents through the combined efforts of the campus, employers and individuals.

Health Centre 2 will offer both the Ülemiste City community and the entire Harju County an even broader range of healthcare services, new medical knowledge, advanced technologies, and an innovative environment for service providers.

The seven-storey, 9,500-square-metre building features an architectural design inspired by natural, organic forms: bone structures, neural networks, the textures of bark and leaves, and the gentle movement of water. The building’s internal layout is centred around a glass-roofed atrium that spans all floors, creating a bright central axis. Wide, curved staircases wind through the atrium, encouraging movement and natural flow.

The landscape architecture concept reflects the building’s core purpose – healing, health maintenance, and improving quality of life. The design also emphasizes environmental sustainability by maximizing the use of local plant species to create a rich and diverse ecosystem that attracts birds and pollinators. Rainwater is collected and reused for landscaping and the rooftop is equipped with a solar panel park to support renewable energy use.

Health and wellbeing are central values for Ülemiste City, along with creating an environment that supports them. The development of the new Health Centre follows the 3×3 Health Model created by the University of Tartu, which provides a framework for supporting the mental, physical and social health of talents through the combined efforts of the campus, employers and individuals themselves.

The new Health Centre will offer both the Ülemiste City community and the wider Harju County an even broader range of healthcare services, new medical knowledge and advanced technologies, while providing service providers with a modern and innovative working environment.

The seven-storey, 10,500-square-metre building follows the concept of Health Centre 2 and has likewise been designed by Apex Arhitektuuribüroo. Its architectural and landscape design draw inspiration from organic forms, while the interior architecture creates a warm, welcoming atmosphere through the use of natural materials, abundant greenery and soft pastel tones.

The anchor tenant of the new Health Centre will be Pihlakodu, one of Estonia’s leading providers of modern elderly care services, which will open a new state-of-the-art care home in the building. In addition to Pihlakodu, the centre will host a variety of other healthcare service providers.

With the addition of Health Centre 3, the Ülemiste City health cluster will expand to more than 27,000 square metres, reinforcing Ülemiste City’s position as the largest privately developed health campus in the Baltics.

Designed to meet all the needs of a modern company, the building is both stylish and representative, yet highly functional and efficient. Seamlessly integrated into Ülemiste City’s innovation-driven environment, the two-part business complex was completed in two stages in 2016 and 2018.

Ernst Julius Öpik was one of the pioneers of Estonian astronomy and among the most distinguished astrophysicists of his generation. In contrast to the increasingly narrow specialization typical of modern science, he sought to approach every question in relation to the broader universe. Similarly, the Öpik Building, which carries his name, has been designed with versatility and interconnectedness in mind. The contrasting black and white surfaces of the façade symbolize the morphological approach characteristic of Öpik’s scientific work.
