Duffield Timber supplied Thermo-Nordic Pine decking, machined to our flat and fluted profile (DTD2), for this multi-level garden deck. Boards laid in changing directions across stepped levels give a traditional, characterful finish.
This garden deck in North Yorkshire uses Thermo-Nordic Pine decking from Duffield Timber, chosen for a traditional look with plenty of natural character.


The deck steps down across several levels, and the boards change direction from one level to the next, some running diagonally. That gives the layout an architectural edge alongside gravel beds, planters and a stone ball water feature.

Thermo-Nordic Pine (Pinus sylvestris) is Scandinavian pine, thermally modified with heat and steam at over 200°C to the Thermo-D class defined by the International ThermoWood Association. The treatment improves its dimensional stability and biological durability Durability Class 2, and the boards keep the species’ prominent grain and sound knots.

The boards were machined to our flat and fluted decking profile (DTD2), developed in-house at our mill in Melmerby, North Yorkshire. Its double-textured face pairs smooth edges with a finely fluted centre, so each board shows a band of texture framed by smooth timber.

Thermally modified boards move less than unmodified pine as they get wet and dry out, which helps a deck with boards running in several directions keep its joints and patterns neat.
