Largest timber construction project will be built in the Netherlands
The largest wooden housing project in Europe, with a total floor area of 18,700 m2, will be built on the edge of the center of Heerhugowaard, The Netherlands, in less than a year. The required 7,300 m3 of wood comes from sustainably managed forests.
The specialized company Hamlet Design+Build Technology from Haarlem is responsible for the design and realization of the wooden hull.
The initiator of the project is the North Holland project developer M.J. De Nijs Projectontwikkeling.
The large-scale timber construction project will consist of 5 residential towers with 200 apartments. The residential towers, of which the highest has 12 floors and is almost 42 meters high, will be constructed entirely from the first floor in CLT (cross laminated timber), including the lift shafts and stairwells.
Hamlet is fully committed to designing and building CLT projects, and in particular multi-layer housing.
In order to guarantee a cost-efficient building, Hamlet works according to the 'design for assembly' principle. “It is important that we arrive at the most efficient design in terms of construction, production, logistics and with regard to ease of construction and construction time. It is an integrated process,” says Hans Lormans, founder and director of Hamlet. “We start with the core, the upper floors and the load-bearing walls. This means that we first design the shell and only then do we start fleshing out the floor plans and the facades”, explains Hans Lormans.
The Hamlet Design+Build Technology team consists of architects, specialized wood constructors and production and assembly specialists, but they also frequently collaborate with external architects, such as in the project in Heerhugowaard, where the Boporai and Mecanoo offices were responsible for the architecture.
According to Niek Schaap, senior project developer at De Nijs Projectontwikkeling and responsible for the Woodstone project, the approach of this project is indeed different than usual, but certainly worth repeating. “By designing from the inside out, you get an efficient shell and a very clear starting point for the architects who work on the houses and facades. Solutions must then be found within the framework of the hull. That takes some getting used to, but you have the certainty as a developer that the project is technically and economically feasible with regard to the CLT application”, says Niek Schaap.
De Nijs appreciated the collaboration with Hamlet, because they are now also working together on a project in Amsterdam.
