Timber Technologies

Today’s timber construction combines the emerging technologies of digital fabrication with a recent renaissance in traditional techniques. Because of the idiosyncrasies of wood as a material, we believe that physical understanding – engendered through hands-on experience – is essential in leveraging the best of timber, even when processes are devolved to computer controlled machining.

Wood can be deployed in a wide range of spatial-structural configurations, each exploiting timber’s particular material properties. This allows a richness of application across building types, matching structural action to the spatial needs of accommodation, shelter and delight.

Freeform and orthogonal structures

The natural flexibility and workability of wood makes it ideal for flowing freeform structures – through elastically bending into network structures like gridshells, or creating complex lamella geometries through CNC machining.
More conventional rectilinear structures suit residential and office buildings, whether single- or multi-storey. Structural arrangements generally fall into arrangements of discrete column and beam elements, or more continuous panel or cellular configurations.

Engineered and natural-form timber

The technologies of glue-lamination [glulam] and cross laminated timber [CLT] allow wood to be composed into high-performance engineered structures. By gluing layers of wood together, the effects of natural imperfections are minimised and consistent high performance structural elements produced. Alternatively, wood used in its more natural forms allows a richer range of species and characteristics to be deployed.

The Den, Royal Exchange

The Den is a striking, ‘pop-up’ theatre space commissioned by the Royal Exchange Manchester for their programme of creative engagement with local communities. The brief called for an environmentally sustainable solution to touring a professional theatre across Greater Manchester. The resulting design – an innovative, modular and kinetic building – is reliant on strong and lightweight glue-laminated Larch components for its structural elements.

Xylotek worked with Hawarth Tompkins and Expedition to design and build a modular structure which can be assembled in three different sizes. This adaptability enables its use in a wide variety of venues as it tours Greater Manchester over the next ten years. At its largest, it measures 15m in diameter, 5m in height and seats 180 people. It requires no foundations or lifting equipment, using instead an innovative system of winches and bespoke bracketry to raise the large circular roof into place.

Larch is lightweight enough that the community can help transport and assemble the building components, and, collectively, turn the fifteen winches to ‘raise the roof’. The timber has the elasticity to allow for use on uneven ground and the strength to support heavy lighting rigs and resist tension from the hardyhemp rope bracing.

The Den had its inaugural outing in Stalybridge in 2019. The strong character of the structure played the role of drawing people into the space and provided a dramatic, enclosed setting for the performances whilst focussing the eye on the central stage. The aesthetic quality of timber against canvas, with the taught ropes casting wonderful shadows in the theatre lights, added to the dynamic atmosphere of the performances.
