HAUT, a residential tower, is a prototype for building innovative and environmentally-friendly high-rise timber structures. The team – Team V Architecture, Lingotto, Arup and JP van Eesteren - built an ambitious sustainable building: a timber skyscraper, with 21 floors one of the tallest timber towers in the world. Never before has this highest sustainability rating - BREEAM Outstanding - been awarded to a residential building in the Netherlands. As a result of the new techniques for a timber hybrid tower of 73 meters high, there is interest from all over the world for this combination of sustainability and urban densification.
SUSTAINABILITY - Unlike concrete and steel, timber production generates no carbon emissions and, in fact, stores carbon. HAUT incorporates various sustainable features, such as solar panels on the roof and façade, ground-sourced cooling, sensor-controlled thermostats for low-temperature floor heating and cooling, nesting boxes for birds and bats, charging points for electric cars, and a rooftop garden with rainwater storage.
HYBRID TIMBER - HAUT's load-bearing structure is made of cross-laminated timber (CLT) panels, manufactured off-site to minimize waste and enable swift, clean on-site assembly. Given the absence of standard regulations for high-rise timber construction, the design team invested significant effort in technical innovation and safety. While floors and walls are timber-based, the wet environmental conditions in Amsterdam necessitated concrete for the foundations, basement, and core.
HAUTE ARCHITECTURE - Leveraging timber construction, HAUT exudes warmth and allows for a high degree of customization, embodying bespoke 'haute architecture.' The adaptability of CLT panels during prefabrication empowers buyers to personalize apartment size, layout, floor count, and the placement of double-height spaces, galleries, and balconies. Unlike typical timber structures, only the inner walls are load-bearing, enabling floor-to-ceiling windows in the façade. The distinctive irregular pattern of balconies and pronounced double-height spaces facing the River Amstel contribute to HAUT's unique architectural identity.
Sustainability
Since HAUT, Team V has been promoting: build with timber where possible, build traditionally where necessary. This innovative project puts timber (CLT) as a constructive building material on the map worldwide. HAUT was the first residential building in the Netherlands with a BREEAM Outstanding label: timber supporting structure, PV in the facade and on the roof, water retention on the green roof, and smart systems.
A complete timber construction proved not to be possible due to the environmental conditions, building shape, the desired transparency and limitations in the subsurface. The team innovatively combined CLT with concrete for the foundation, basement, and elevator core, optimizing material use and reducing CO2 emissions. Navigating the lack of guidelines for tall timber structures, the team focused on fire safety, noise control, and vibration transmission.
HAUT's impact extends across three levels: climate contribution through reduced CO2 emissions, enhanced living environments with distinctive architecture, and improved living quality featuring spacious outdoor areas, personalized living spaces, acoustics, comfort, and high-quality finishes. The 52 owner-occupied homes, built for longevity, boast a main supporting structure designed to last over 100 years. Additionally, the PV panel facade is easily replaceable, ensuring HAUT's sustainability in the long run.
