From pallets to palaces: advanced high-rise buildings built from waste wood, The Urban Woods Delft (NL)

The Netherlands has the scoop: building with waste wood. The Urban Woods, known for its subscription-based modular homes, turned the first screw in a massive building plate for their modular homes yesterday, June 26. This “breakthrough for CO₂ issues” is the result of a chain-wide collaboration.

The Netherlands has the scoop: building with waste wood. The Urban Woods, known for its subscription-based modular homes, turned the first screw in a massive building plate for their modular homes yesterday, June 26. This “breakthrough for CO₂ issues” is the result of a chain-wide collaboration.

From garbage heap to residential tower

The Urban Woods Delft is a 10-story high-tech apartment complex, mostly without concrete. Even the core and elevator shaft consists of recycled wood, treated for centuries. “Unbelievable,” says co-founder Tim Vermeend. “One billion pallets a year were thrown away, and now... we're living in them!”

Sustainable Dutch Innovation

The cross laminated wood (C-CLT) used is made from discarded pallets and scrap wood, finished with ash wood — not softwood. This circular material complies with European regulations, reduces CO₂ emissions and is 10-15% stronger than traditional CLT. It is a forerunner in biobased construction, a sector in which the government is investing 200 million euros.

Cooperation as a Key

This milestone is the result of a broad collaboration. Staatsbosbeheer supplies ash wood, DZB Leiden processes waste streams, Wood Joint fingerload planks and Boer Boom turns it into solid panels. The Urban Climate Architects designs, TNO investigates quality, and the Province of South Holland co-finances.

Scalable and Local

Production is being scaled up with the world's first C-CLT vacuum press for recycled wood. “One turn of a propeller, but a turning point in the construction transition,” it sounded at the ceremonial screw installation. A small action, a big step towards a circular future.

From pallets to palaces with C-CLT and biobased high-rise buildings

New value from waste wood

What if waste wood becomes the basis for high-rise buildings. In this study, we show how waste streams transform wood into high-quality building materials with C-CLT.

In The Urban Woods in Delft, this comes together in a building where biobased construction and sustainable construction be at the center. This is where a new way of building is being created in which materials do not end, but start over.

C-CLT as the next step in timber construction

With C-CLT and CLT construction Netherlands we are setting a new standard building solid wood. Where traditional CLT uses new wood, C-CLT uses residual flows such as pallets and waste wood.

This ensures:

  • maximum reuse of raw materials
  • strong reduction in CO2 emissions
  • scalable circular building systems

This is how it grows timber architecture Netherlands on to a circular future.

Circular construction as a system

This project shows how circular construction in the Netherlands goes beyond reuse alone. It's about a system in which materials retain their value.

If timber construction architect we are working on solutions that are scalable and contribute to a new building culture.

Low-impact urban densification

The use of C-CLT creates space for urban densification with minimal environmental impact. High-rise buildings thus become a sustainable solution instead of a burden on the city.

Circular CLT and biobased high-rise buildings as the future of construction

From leftover material to architecture

Instead of seeing waste as the end point, we use it as a start. With C-CLT residual wood is converted into high-quality building materials for high-rise buildings.

This research shows how biobased construction and CLT construction Netherlands come together in a circular system where materials continue to circulate.

Innovation in engineered timber

With engineered timber buildings NL and C-CLT creates a construction method that preserves raw materials and creates new value.

Benefits of C-CLT

  • high-quality reuse of wood
  • lower CO2 emissions
  • suitable for large-scale applications

Circular economy as a foundation

This project is a powerful example of circular construction in the Netherlands and the transition to a circular economy.

If building transformation architect and innovator, we are working on systems where materials are never lost.

From building to scalable solution

The real impact of C-CLT lies in scaling up. It makes circular timber construction applicable on a large scale, from homes to high-rise buildings.

Here comes sustainable architecture Netherlands along with innovation and impact.

The future of construction is circular

With C-CLT, the construction sector is moving from linear to circular. This is the next step in sustainable construction and biobased architecture.
