HasleTre: Oslotre’s Pioneering Timber Office in Norway, a Sustainable Beacon of Innovation

In the heart of Norway's capital, Oslo, Oslotre has unveiled HasleTre, a groundbreaking timber office transcending conventional design boundaries. Beyond its functional role as a five-story office space for charity Save the Children, HasleTre represents a new frontier in sustainable architecture. This article delves into the innovative features of HasleTre, from its easily disassembled timber structure to its commitment to environmental consciousness and adaptability.

Oslotre's design philosophy for HasleTre revolves around creating a structure that serves its present purpose and as a "materials bank" for future construction endeavors. The architects adopted a timber-centric approach, utilizing a 5x5 meter timber grid structure that is entirely steel-free. This decision not only reduces embodied carbon but also facilitates the future disassembly and reuse of all components.

Lead architect Moritz Groba emphasized the strategic use of large timber dowels to connect structural elements, timber nails instead of screws for fixings, and wood insulation in the walls. Groba envisions HasleTre as a blueprint for the future, stating, "we view the building as a material bank for future construction if HasleTre reaches the end of its lifespan."

Designing with Dimensions in Mind:

Internally, HasleTre is a testament to the integration of design and functionality. The office spaces are organized based on the dimensions of the timber frame, fostering a sense of harmony and efficiency. Wood and curtain dividers delineate meeting rooms, while larger banks of desks and communal spaces are framed with stepped seating.

The interior design maximizes the exposure of the timber construction, promoting the health benefits of working in spaces with exposed wood. Full-height windows illuminate the office spaces and connect the interior with the lush surroundings, creating a seamless blend of nature and architecture.

Shingles, Sustainability, and Synergy:

The exterior of HasleTre is clad in shingles of heartwood pine, chosen not only for its aesthetic appeal but also to reference the neighboring brick building's palette. The heartwood pine shingles will weather over time, creating nuanced shades of grey and brown. This deliberate choice of materials demonstrates Oslotre's commitment to sustainability and integrating architectural elements with the natural environment.

The architects also made conscious decisions regarding materials used in the interior. Reused and recycled materials were employed for acoustic ceiling plates and flooring, and 60% of the furniture is upcycled. The remaining furniture is crafted from biodegradable or waste materials, ensuring a cohesive commitment to environmental responsibility.

Encouraging Sustainable Mobility:

Recognizing the impact of transportation on the environment, HasleTre incorporates facilities to encourage sustainable commuting. Cycle parking spaces are provided alongside the building, with the basement housing changing rooms and showers for staff who cycle to work. This commitment aligns with the broader vision of creating a sustainable, eco-friendly workspace.

HasleTre stands as a testament to Oslotre's design prowess and a beacon of innovation in sustainable architecture. From its easily disassembled timber structure to its meticulous consideration of materials and spatial organization, HasleTre represents a harmonious blend of functionality, environmental consciousness, and adaptability. As the world seeks sustainable solutions, HasleTre emerges as a symbol of what is possible when visionary design meets a commitment to a greener, more sustainable future.
