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.

SD Structures re-engineered an initial concept design for our new hotel and restaurant 'Redchurch Townhouse' and overcame a number of technical issues to produce an efficient structural design under time pressure to help keep the programme on track. They developed solutions to simplify construction and provide additional usable space in the narrow basement. Their creative thinking and exceptional level of service has lead to a close working relationship forming between SD and Soho House for future projects.

I have worked with SD Structures on a number of development projects whilst at Uplift. They have always been extremely proactive and responsive throughout the project. Our projects are often on complex sites but SD's experience means we can always maximise the potential of each acquisition with intelligent, cost effective solutions. Since joining Engie (Keepmoat) I will be recommending SD for our developments.

There are many reasons why we engage SD Structures on our projects, but their enthusiasm and passion for well-considered design solutions stands out probably the most. Their thorough approach not only results in elegant and neat architectural detail, but also often offers cost savings thanks to specific structural solutions that are based on an in-depth understanding of each project. Their professional and efficient work ethic turns challenges into exciting solutions. It is a true joy to work with such an engaging and highly competent team.
