Osian Denman is a skilled carpenter, timber framer, and sawmill owner whose work spans from traditional post & beam structures to precision custom milling and woodland management. He brings extensive knowledge and hands-on experience across all aspects of building, from site management to the safe coordination of heavy cranes and plant equipment during assembly.

Operating one of the few independent sawmills in Ireland, Osian specializes in off-standard milling bringing out the natural character and strength of every log. From storm-felled giants to carefully selected native hardwoods, his craftsmanship bridges the forest and the frame, ensuring each beam or board tells the story of the tree it came from.
