Ty Sanctaidd serves as a multifunctional meeting, retreat, and events space, elegantly situated within a small woodland in Pembrokeshire. The design mandate called for a 20-meter diameter timber-framed roundhouse that would harmoniously integrate into its scenic coastal environment. The building was constructed to adhere to stringent sustainability standards, utilising locally sourced Douglas fir, milled by ourselves. Eco-building workshops were integral to the construction process, engaging the community and enhancing the project’s sustainable ethos. The structure features straw bale infill walls, rendered with clay and lime, and a roof insulated with sheep’s wool, topped with cedar shingles.

Precision and attention to detail were paramount throughout the construction process. Drawing on our experience in boat building, we developed custom jigs and assembly techniques to achieve millimeter precision, ensuring the perfect alignment of the concentric circles of the ring beam, collar tie ring, and rooflight. The structure was prefabricated in two halves in our workshop, incorporating a modular soffit system with concealed gutter. The meticulous details of Ty Sanctaidd—from the conical roof achieved by the use of curved purlins to the symmetry of the reclaimed Georgian pine flooring that mirrors the overhead timber rafters—showcase our commitment to craftsmanship. Notably, doors crafted from ash trees felled to accommodate the build underscore our dedication to sustainable practices. This meticulous attention to detail is evident throughout Ty Sanctaidd, inviting all to witness its beauty and craftsmanship in person.
