What English Oak Buildings does
English Oak Buildings is a UK-based bespoke construction company founded in 1999 that designs, fabricates, and raises green oak-framed structures for private residential and commercial clients. Operating under English Oak Buildings Limited from its workshop at Bassett Farm, Claverton, Bath, the company produces oak-framed houses, barn conversions, extensions, roof trusses, garden rooms, garages, porches, swimming pool structures, and garden architecture using traditional mortise and tenon joinery secured with handmade oak pegs, with frames pre-assembled in the workshop before delivery to site.
The company's product portfolio extends beyond core framing into complementary offerings including Oak Glu-Lam Beams, Structural Insulated Panel Systems (SIPS) and warm roofs, encapsulation, oak and timber cladding, and conservation services for listed and heritage buildings. Its exclusive proprietary product, the Black Pig Direct Glazing System, is owned by and only available from English Oak Buildings and is positioned as a differentiator for direct glazing into oak frames. The firm holds memberships with TRADA and the Association for Environment Conscious Building (AECB), and has been recognized with a LABC Building Control award.
The business model is one-time, project-based revenue from bespoke commissions with no publicly disclosed pricing. Customer acquisition is sales-led via the company website (enquiries and brochure requests) and indirect referral channels through architects and contractors. The company provides a 10-year structural guarantee, has completed hundreds of frame-raisings, and operates UK-wide with dedicated county service pages across more than 25 regions including the Channel Islands. Ownership is founder-led under Rory Millar as Founder and Managing Director, with no external investment or parent company disclosed.
