SD Structures are a dynamic London based structural design practice focused on quality architectural and structurally challenging projects, big and small. We are experienced chartered engineers, who add value to projects by designing well detailed and efficient structures.

The practice was established in 2014 with a focus on providing high quality structural engineering design services. We have a wide breadth of experience in structural design across the domestic, residential, commercial, education and cultural sectors. Our versatility means we can add value on a broad range of projects from domestic refurbishments, to £100m commercial new builds, or maximising the number of storeys we can add to an old structure. Based in central London, we cover the whole of the south east and beyond.

We work in 3D (Revit) on all scales of project and can even produce integrated 3D design of connections, temporary works and RC detailing with the main structural framing. We use the latest 3D modelling software to design structures efficiently whilst using BIM integration (level 2+) to coordinate with architects and services engineers on our larger projects. Our collaborative approach and search for efficiency saves our clients time and money when projects are onsite.

Our clients say they like working with us because of our professional, personable and responsive approach combined with our attention to detail and passion for what we do. We don’t simply find an engineering solution to a problem, we are proactive and work hard to find the optimum solution for the project. This has lead to our growing reputation for innovative, cost effective and practical structural solutions.


Having now worked on numerous projects together with SD, it is their ability to provide innovative and well-considered engineering solutions that set them apart. Importantly they approach every project as a collaboration with a desire to maintain the architectural aesthetic while providing responsive and cost-effective structural solutions.
