Katajanokan Laituri, a new wooden building in the heart of Helsinki, stands as a testament to sustainable architecture. Designed by Anttinen Oiva Architects, this building incorporates innovative construction methods, providing insights that are particularly relevant for architects, interior designers, and landscape architects. Located beside Helsinki’s Uspenski Orthodox Cathedral, Katajanokan Laituri is home to the head office of Stora Enso, a Finnish forest industry company, and Solo Sokos Hotel Pier 4, which aims to be Finland’s most sustainable hotel.

Wood as a Material for a Sustainable Future
Wood construction is an essential strategy for creating a more sustainable urban environment, and Katajanokan Laituri showcases how traditional materials can be used in innovative ways to contribute to a carbon-neutral future. The four-storey building is made from Finnish and Swedish timber, featuring solid wood load-bearing elements supplied by Stora Enso. By incorporating locally sourced wood, the project not only reduces carbon emissions associated with material transport but also highlights wood’s potential as a renewable building material that sequesters carbon throughout the building’s lifetime.

Katajanokan Laituri features visible wooden structures throughout the interior, emphasizing the natural beauty and warmth of the material while offering an inviting and tactile experience for visitors. The emphasis on exposed wood demonstrates how natural materials can be both aesthetically appealing and functional, creating spaces that feel connected to nature. For interior designers, this approach presents opportunities to incorporate biophilic design principles, enhancing the well-being of occupants through natural elements.

Nature and Technology in Harmony
The building integrates sustainable technologies, including solar panels and a multi-species green roof, which contribute to its overall efficiency and environmental performance. A small birch forest grows within the atrium of the hotel, blending nature with the built environment and offering a tranquil escape for guests. These elements reflect a holistic approach to sustainability that goes beyond material choices, embracing both natural features and renewable energy solutions.

Flood resilience is also a key feature of Katajanokan Laituri, with the building designed to withstand water level rises of more than three metres. This future-proofing aspect is critical for urban developments situated near water, and it demonstrates the importance of integrating climate resilience into architectural projects.

A New Hub for Art, Design, and Sustainability
The development of Katajanokan Laituri aligns with Helsinki’s goal of becoming carbon-neutral by 2030. By enhancing the city’s 131-kilometre shoreline and creating lively urban spaces, the building contributes to a more accessible and vibrant urban environment. The area is set to become a new hub of art and design, especially with the upcoming Museum of Architecture and Design.

Solo Sokos Hotel Pier 4, located within the Katajanokan Laituri building, aims to be the most environmentally sustainable hotel in Finland. The hotel will seek LEED Platinum certification, ensuring a commitment to high environmental standards. It also plans to apply for Green Key and Sustainable Travel Finland certifications, demonstrating a comprehensive approach to sustainability in its operations, materials, and services. The hotel’s restaurant, led by Michelin-starred chef Sauli Kemppainen, also follows a sustainable philosophy, focusing on Finnish and Nordic ingredients, with up to 85% of all produce being locally sourced.

Katajanokan Laituri serves as an inspiring example of how sustainable design can be integrated into both public and private spaces, providing valuable insights into material innovation for architects, interior designers, and landscape architects. The building’s use of renewable materials, energy-efficient technologies, and biophilic design principles makes it a noteworthy model for future sustainable developments.
