HoHo – wooden skyscraper 

With the HoHo in Vienna creates an OTHER, new type of commercial space. Commercial areas for restaurants, health, beauty, wellness, business, hotel and apartments extend over 24 floors. With a total height of 84 meters and 24 floors, the HoHo is currently one of the tallest wooden skyscrapers worldwide. It comprises a total gross area of ​​25,000 m², of which 19,500 m² is rental space and 3,920 m² of land. If you look at the HoHo Vienna from the outside, you think of huge wooden blocks that are put together in a triangle. Naturalness to the outside and visibility of the wooden surfaces also in the interior are part of the core idea for a tangible experience of the element wood.

The HoHo Vienna not only looks stylish and exudes natural charm, but also demonstrates creativity when it comes to space use: the modular office structure allows individual changes that can be changed at any time without much effort. This flexible floor plan also ensures that this wooden high-rise building never loses its attractiveness for tenants, as it can guarantee very long use in a friendly atmosphere. The holistic concept by architect Rüdiger Lainer stages the feel-good factor of its own accord, because this "comfort" can be experienced every day for everyone who walks by and for everyone who goes in.
