Residential Structural Engineer Guide

With so many of us spending more time at home, everyone is looking at how to maximise their space. If you want to adjust the layout of your home or create a house extension, this type of renovation is always best managed by a structural engineer to ensure it’s viable and safe. If you plan to self-build, it’s critical that you use a structural engineer as you plan.

They will assess the structural condition of a property and then recommend and calculate a plan for the types of materials you should use, plus their weights and dimensions. Their work also includes any civil designs required by the project such as retaining walls, road design and drainage needed for Building Control Approval.

How Much Does A Structural Engineer Cost Uk Wide?

A structural engineer survey cost will always depend on your property, the area of the country you are in and what you want to achieve from your house extension London, but there are common tasks that attract typical fees, such as building surveys and measurements for conversions.

A residential structural engineer will typically charge up to £90 per hour, then the size of your property will affect the length of time for assessment. You could budget for a minimum of four hours for a small flat and up to five days for a large detached house.

Ultimately, the scale and complexity of your job will dictate the overall cost. If it’s a large project, the structural engineer will need to visit several times and may need to adjust technical drawings as requirements change. For example, a single-storey extension or removal of a load-bearing wall could be viewed as a simple project, but a double storey extension of more than one floor on uneven ground would necessitate additional work.

Sometimes the structural engineer will need to ask your builder to perform tasks to assess the depth of the foundations of your home, for example. This can then inform as to whether you need underpinning to prevent subsidence.
