Building with Roundwood Douglas Fir: A Strong, Sustainable Choice from Longwood

A stunning new extension and balcony built by our friends at Ty Pren is a perfect example of what can be achieved with roundwood Douglas fir construction using timber harvested from Longwood. This natural building method is gaining attention for its strength, sustainability, and beautiful organic appearance. If you’re looking for a construction approach that combines traditional craftsmanship with modern environmental values, roundwood framing is an exceptional option.

Sustainable Frame

Why Choose Roundwood Construction?

Roundwood construction uses timber in its most natural form. Instead of milling the wood into square beams, each stem is kept round, preserving the tree’s original strength. This means the timber retains its natural fibres and structural integrity, resulting in stronger, more resilient beams. Builders often comment on how roundwood frames feel “alive” within a structure, bringing warmth and character that sawn timber simply can’t replicate.

Another major benefit is sustainability. Roundwood timber requires minimal processing, which significantly reduces embodied energy. With fewer industrial steps involved, the carbon footprint of a roundwood frame is much lower than conventional construction materials. Because the timber is used in its natural form, the overall build process is simpler — and this often means roundwood construction works out cheaper than conventional timber‑framed building. Less milling, fewer processed components, and shorter supply chains all contribute to lower costs.

Roundwood Sustainable Building

Local Craftsmanship, Local Timber

The extension and balcony created by Ty Pren showcase how roundwood Douglas fir can transform a building. Douglas fir is naturally durable, making it ideal for outdoor structures. Its warm colour and organic curves create a unique aesthetic that blends seamlessly with the landscape.

By choosing roundwood Douglas fir from Longwood, builders support local woodland management, reduce transport emissions, and invest in sustainable craftsmanship. Click here to get in touch to discuss your next project — we’re always happy to help.
