project overview
OSG Architecture was appointed by EQT Real Estate as Building Regulations Principal Designer (BRPD) on the Storex Brentford site, delivering statutory duties under Part 2A of the Building Regulations in line with the Building Safety Act 2022. The project is a major new-build, standalone self-storage development located just off the A4 in the heart of Brentford, West London, where clear, co-ordinated compliance evidence was required from the outset.
The scheme comprises 11 storeys of self-storage accommodation, making it the tallest facility of its kind in Europe, alongside affordable ‘Fab Lab’ workspace supporting local creative and light industrial uses. From a BRPD perspective, this required careful coordination of information across different occupancy types and regulatory Parts. OSG supported the team by:

Building Regulations Principal Designer
our role as BRPD
OSG acted on behalf of the client to assess and coordinate the design team’s information. This included reviewing architectural designs, structural input and building services strategies, identifying compliance gaps early, and guiding consultants to align their work with Building Regulations requirements.
sustainability and regulatory alignment
We also led co-ordination activities across fire and access strategies, façade/interface details and building services routing, ensuring documentation supported a safe and deliverable proposal. Sustainability measures such as a blue roof attenuation system and PV solar arrays were incorporated into the scheme. While OSG was not responsible for their design, our role as BRPD was to ensure that information relating to these features was properly coordinated and clearly referenced within the Building Regulations submissions. We worked with the design team to ensure:
■ Sustainability measures were appropriately reflected in the compliance information
■ Evidence aligned with the relevant requirements of Parts A through T
■ The documentation presented a clear, coherent narrative for approval
Throughout, OSG maintained clear communication channels to keep duties and actions visible to all dutyholders.
confidence, compliance & clarity
We helped establish a compliance roadmap that allowed our client to make informed decisions and avoid costly redesign later in the programme. Our work will support the project through the declaration process by providing auditable, organised information and drawing attention to unresolved items before submission.
value to the client
Our BRPD involvement helped our client and the wider design team understand the implications of design decisions on compliance, reducing uncertainty and supporting project progress.
■ Reduced regulatory risk through early-stage issue spotting
■ Clearer design responsibilities shared across the team
■ Improved coordination between structure, MEP and architecture
■ Documented compliance trail supporting decision making
■ Alignment with evolving Building Safety Act requirements
The scheme represents a significant step forward for Storex’s UK portfolio, providing high-quality self-storage and affordable workspace within a well-structured regulatory process. OSG’s role as BRPD ensured the Building Safety Act journey was well-managed, proportionate, and aligned with the project’s commercial objectives, supporting a successful path to declaration and approval.
outcome
The project is progressing with a clear strategy for compliance in place and an evidence base sufficient for onward regulatory review. EQT Real Estate continues to work with OSG across multiple developments, benefiting from our developing frameworks for BRPD delivery and Building Safety Act compliance across a growing portfolio.
