ELIGE MADERA Reaching High with Wood: HoHo Vienna CLT high-rise construction is becoming increasingly common, demonstrating the capabilities of wood for sustainable projects and serving as an example of hybrid construction. CLT high-rise construction is becoming increasingly common, demonstrating the capabilities of wood for sustainable projects and serving as an example of hybrid construction. HoHo Vienna is a hybrid CLT and concrete high-rise project from investor Günter Kerbler that aims to be a disruptive element in a city known for innovation and sustainability. Under the direction of Caroline Palfy, the construction of the world's tallest wooden building started in 2016. The 84-meter-high project consists of a main constuction of three attached buildings (9, 15 and 23 floors,) and a secondary 5-floor building, as explained by the site Madera y Construcción. The composition of the building was based on three basic elements: support, ceiling panels and facade. For the main support, the vertical communication of the cores was envisioned, materialized in concrete, and clad with CLT structures. For the ceiling panels, concrete perimeter beams and CLT panels were used. They were assembled with the vertical structure according to the "system node" technique, which provides vertical and horizontal traction anchors in the CLT panels of the roof, resulting in a resistant wood slab. For the final element, a facade was chosen to expose the wood structure, consisting of CLT panels. For the assembly of the exterior walls of the building attached to the main structure, the window openings and dimensions of each section were considered in the prefabrication of the panels. The project, which took 3 years to materialize, is now an example of creativity and sustainability in architecture - a skyscraper that inspires connection to nature within the city.
