Cross Laminated Timber (CLT) or Massive Wood is the answer.

HOLZ Panel CLT is 100% sustainable and origin identifiable. It removes the need for concrete and steel throughout much of the build process and can be used as easily in a domestic house construction as a multi residential unit construction.

CLT is used extensively across Europe, and is available in completely fabricated packages, meaning that onsite construction takes only a fraction of the time of a conventional build.

For further information on CLT please see the attached fact sheets.
