Expert Builders and Architectural Designers in Pontypridd & South Wales

Welcome to RDM Design & Build, your trusted local building contractors and CIAT Chartered architectural designers. Based in Church Village, Pontypridd, with satellite offices in Pontyclun and Sully we cover the whole of South Wales and specialise in taking your property dreams from the very first sketch right through to the final brick.
Whether you are looking for a reliable builder to extend your family home, or an expert architectural designer to navigate complex planning applications, our expert team manages the entire process under one roof. By combining creative architectural design with high-quality construction, we save you the time, stress, and miscommunication of dealing with separate architects and building companies.
