A significant update in Building Regulations is the introduction Principal Designer (BRPD). So what is the role of principal designer on a self-build project?
One of the most significant updates in recent changes in Building regulations is the introduction of the Building Regulations Principal Designer (BRPD). The role of BRPD is not just for self-builders—it is a fundamental shift in the industry. It is designed to influence how architects, consultants, and construction professionals collaborate to ensure robust compliance.
How does the introduction of the Building Regulations Principal Designer (BRPD) role affect you as a self-builder?
The legislative updates are focused on improving construction compliance, safety, and sustainability. To counter these issues, the government has created this new role. The BRPD’s core function is to embed regulatory compliance, safety, and sustainability from the earliest stages of a self-build project. This proactive approach involves coordinating with design teams. Identifying risks before they cause delays. Managing all documentation for regulatory approvals, and ensuring designs meet the highest energy and sustainability standards.
This new requirement for principal designer on a self-build project is in addition to the existing obligation under the CDM (Construction Design and Management) Regulations 2015. The CDM role focuses on planning, managing, monitoring, and coordinating health and safety during the pre-construction phase of a project, including domestic ones. Consequently, clients now face the requirement of making two separate Principal Designer appointments. Both of which must be confirmed before construction commences.
For domestic projects, if only one designer is involved, that individual must perform the duties for both the CDM Regulations and the new Building Regulations principal designer role. Clients can satisfy the Building Regulations requirement by appointing the same person who holds the CDM principal designer role. Critically, if no principal designer is formally appointed, those duties fall to the client.
