Why do I need a structural engineer for my extension?

If you have an idea of what your home extension should look like, you might ask an architect to draw it for you. Structural engineers will tell you how to build your project; we calculate safety, viability and resilience so that your plans meet local authority regulations. We will talk you through all of the stages of building an extension that require the services of a structural engineer. Laytoe offers site surveys, structural calculations and drawings for all property types – detached, semi-detached, terraced and maisonette.

What does a Laytoe structural engineer do?

Starting with foundations; we assess soil conditions and the water table of your area to determine what type of foundation is suitable for your project. Before any walls can go up, some might need to come down – for load bearing walls, you need a structural engineer’s report to satisfy your local planning department. Laytoe’s structural engineers build safety and cost-effective measures into the design of all proposed new walls, joists and lintels so that they adhere to building regulations. Watertight and durable roofing has to meet industry standards, from the material used to construct and cover your roof, to the style that is compatible with your project. Our team ensures that all support structures and beams are tested so that your build is topped off safely.
