Home Extensions

& Alterations

Structural design is at the core of every home extension and alteration project. It ensures your new space is safe, compliant, and seamlessly integrated with the existing structure, supporting both performance and long-term value.

At Rivet Engineering, our approach to home extensions and alterations is focused on delivering practical, buildable structural solutions. By understanding the existing structure, project requirements, and site conditions, we ensure every design is safe, compliant, and ready for construction.

AS AN AWARD-WINNING ARCHITECTURAL PRACTICE, OUR TEAM OF EXPERTS UNDERSTANDS THAT A SUCCESSFUL PROJECT IS RELIANT UPON A PROACTIVE AND FLEXIBLE DESIGN TEAM.

How We Approach Structural Design?

Our approach focuses on delivering practical, buildable solutions supported by clear calculations and detailed drawings. By understanding load paths, structural behaviour, and construction requirements, we ensure every design is safe, compliant with UK Building Regulations, and ready for a smooth and confident build.
