Commissioned by the listed office investment company NSI, Dam & Partners Architects have designed a wooden office building for Zuidas that will be 86 metres tall. It is set to be one of the world’s tallest wooden office buildings.
Since Friday, 12 June 2026, it has become clear that the development of Well House in Vivaldi by office investor NSI will definitively not proceed. NSI has announced that the financial substantiation does not meet the real estate investor’s investment criteria. At 86 meters, Well House was set to become one of the tallest wooden office buildings in the world. Construction was originally scheduled to begin in 2022, but construction costs and market uncertainties caused the project to be temporarily halted.
Prominent position
The building was set to be be located on a very prominent position: at the end of the new Maurice Ravellaan, where the new Ravel residential district will be situated. The Maurice Ravellaan forms the extension to Gustav Mahlerlaan, as a result, the wooden tower would have been visible from Parnassusweg.
Sustainable, healthy building
Well House should have been a sustainable building, with sustainable construction techniques, sustainable and optimally reusable materials, a roof terrace with trees and greenery, and a healthy building for the people who would work there. The aim was to achieve the highest sustainability certificate, BREEAM-NL Outstanding.
Public areas
The wooden building was going to have a gross floor area of 22,000 sq. m., and the standard gross floor area for each floor would have been be approximately 1,100 sq. m., the ground floor smaller. Between 500 and 3,200 sq. m. of the floor area was intended for publicly accessible rooms. The lowest floors for public amenities and flexible workplaces. The idea behind the design is that the outdoor public space and the public rooms would be linked.
