Timber Framing


Oak timber frame joint detail

We design, fabricate, and assemble bespoke timber frames in green oak and Douglas Fir. From garden rooms and porches to full house frames and agricultural buildings — every frame is cut at our Welshpool sawmill and raised on your site by our crew.

How It Works

It starts with a conversation about what you want to build. We produce CAD drawings, engineer the frame, cut the joints on our CNC, trial-assemble in the workshop, then deliver and raise on site. The timber comes from our own woodland or trusted local sources — you know exactly where every beam was felled.

Oak Or Douglas Fir?

We work in both species and recommend the right one for your project. Oak is the traditional choice — strong, durable, beautiful. Douglas Fir is a cost-effective alternative with the highest strength-to-weight ratio of any softwood. Same design service, same fabrication quality, different price point.
