Our structural calculations ensure projects meet safety and regulatory standards. Services include load assessments, material specifications, and reinforcement plans for extensions, basements, and new builds. Clients receive precise technical documentation for construction teams.
Building Control
We produce detailed drawings and specifications for building control approval. Our submissions address fire safety, insulation, and accessibility requirements. Clients gain confidence in meeting legal standards while avoiding costly revisions during construction.

We design loft conversions to create functional living or commercial spaces within existing roof structures. Our solutions optimise headroom and structural integrity while securing necessary approvals. Clients gain additional usable space without expanding the building footprint.
