STRUCTURAL ENGINEERING
What does a structural engineer do? A homeowner’s guide
Understand what a structural engineer does, how they work with architects and builders, and what to expect when planning changes to your home.

Start with the decision
A structural engineer considers how a building carries weight and stays stable. That includes the parts you can see, such as walls and columns, and those hidden beneath floors or below ground. For a homeowner, this becomes relevant when a proposal changes how the building is supported: opening up a room, adding an extension, converting a loft or investigating a particular structural concern. At Hey Structure, we start with what you want to achieve and the information available about the property. An architect may develop the layout and appearance, while the structural engineer considers how the proposed arrangement can be supported. The builder then carries out the work using the coordinated project information. These roles work together, but one appointment does not automatically include everything the others provide.
Keep the scope proportionate
The work should match the question being asked. Advice on whether a layout is feasible is different from a detailed design package, and both differ from an inspection of an existing defect. Depending on the agreed brief, an engineer may review drawings, inspect accessible areas, identify further information needed and prepare calculations, drawings or a written report. It is useful to ask what each document will help you do. Will it inform a design decision, support contractor pricing or form part of an approval submission? Also clarify who coordinates queries and whether visits during construction are included. A structural appointment is not automatically a whole-building survey, a planning service or continuous supervision of the contractor. Clear boundaries help you arrange the other support your project needs.
Turn information into action
Before making an enquiry, gather the property postcode, a short description of the changes and any drawings or photographs already available. Explain what matters most to you, whether that is a wider opening, a particular room arrangement or understanding a concern before purchase. You do not need to solve the engineering problem yourself. Tell us which decisions are still flexible and whether another professional is involved. We can then discuss the appropriate scope and the information needed for a fee proposal. Keep the agreed deliverables and current drawing revisions together as the project develops. If the proposal changes, ask whether the structural design needs reviewing before work proceeds.
