Double Your House for Half the Money

Based in Staines, Structural engineering services work with clients specialising in creating reliable practical structural designs & calculations across London, as much as surrounding counties. Our structural engineers work with different building types while drawing structural calculations for an extensive variety of purposes. This includes swimming pools, basements, loft conversions, extensions, new build homes and commercial projects.

Our structural engineers’ design both new and retrofit basements for either commercial or domestic use including basements under gardens. Structural engineering basement services include site investigation reports, trial holes, party wall monitoring and site visits throughout the construction phase. We have experience in various underpinning methods, including those in difficult ground conditions. Our work also involves properties that have experienced movement and require the traditional underpinning.

There are numerous ways to design a basement while our structural engineers evaluate the ease of construction. Also, the feasibility and cost of the project will get taken into account. A carefully and well-thought-out structural basement design can limit expenditure in build costs. Consequently, the project time frame can be condensed as well.


We offer a free quote service where you can call or message us to discuss your ideas so we can answer any queries you have, by appointment, we visit your property and from there draw up a quote.
