A single or two-storey extension is a great way to add a bigger kitchen, a family room or an extra bedroom. Whether you are building out at the rear, the side or both, Building Control will need structural calculations showing that the new foundations, beams and walls are safe, and that any openings into the existing house are properly supported.
Teign Designs provides house extension structural calculations by a chartered civil engineer (CEng MICE) for homeowners, builders and architects across Teignbridge, Torbay, and South Hams.
What’s included
- A site visit to check the existing house, the ground conditions and how loads can be carried down
- Foundation design for the new walls, including advice near trees, drains and boundaries
- Steel beam design for knock-throughs into the extension, plus padstones, bearings and any posts needed
- Floor joist, roof and lintel sizing for the new structure
- Clear structural calculations and professional CAD drawings for your builder and Building Control
- A package ready to send to Building Control, with any of their questions answered
Common jobs
- Single-storey rear and side extensions
- Two-storey extensions
- Wraparound extensions
- Kitchen extensions and open-plan living spaces
- Knocking through the back wall of the house into the new extension
Working with your builder or architect
If you already have a builder or architect on board, Teign Designs works alongside them so the structural design fits their plans and the build runs smoothly. If you are at an early stage, the calculations and drawings give your builder a clear basis to price the work.
Why use a chartered engineer?
Chartered status means the design is checked to recognised professional standards. That gives you, your builder and Building Control confidence that the work is right first time.
