It’s best to involve GC Robertson at the start of your project. Early input helps identify structural solutions, avoid costly design changes, and ensure your plans meet Building Regulations.
Yes, extensions require structural design and calculations for approval. GC Robertson provides the drawings and reports needed to make your extension safe, compliant, and buildable.
Loft conversions almost always require structural input. We design the beams, floors, and supports to ensure your new living space is structurally sound and meets regulations.
No, it’s unsafe to remove a load-bearing wall without professional design. GC Robertson specifies the correct beams and supports so alterations can be carried out safely and approved by Building Control.
A structural survey is a detailed inspection of a property’s structure. GC Robertson provides clear reports on issues such as cracks, movement, or subsidence, along with practical recommendations.
Many projects fall under Permitted Development and don’t need planning permission. However, Building Regulations approval is always required, and GC Robertson supplies the calculations and drawings for compliance.
Often both are needed. Your architect creates the design, while GC Robertson ensures the structure can be built safely and cost-effectively.
Yes. Our engineers design foundations suited to your site conditions, ensuring your extension is stable, compliant, and built to last.
GC Robertson provides detailed structural drawings and calculations. These documents are used for Building Control approval and guide your contractor during construction.
Early involvement allows us to test feasibility and identify cost-effective solutions. This means smoother approvals, fewer delays, and designs that are practical from the start.
