About Us

Client Focused • Innovative Solutions • Superior Design.

Our practice was established in 1989 by Stephen Walsh, underpinned by a passion for the art of engineering, and a desire to simplify the most complex issues into buildable projects for our clients.

Since that time we have grown to a workforce of over 130 employees based at our London Headquarters.

Despite our growth we have always maintained our ‘client first’ approach – applying our technical expertise to your projects through our team of talented engineers & consultants; supported by the use of the latest technology to bring your project to life.

Our Beliefs

Putting You First • Engineering You Can Count On

Operating with an ethos of honesty, transparency and open communication internally and externally has always been a cornerstone of our practice.

We are directed by Engineers & all of our projects are allocated to one of our highly experienced Directors, ensuring your needs are at the forefront of all we do. Our commitment to continuous improvement will always remain important to us, and this is instilled in our entire team.

We are able to provide you with the full remit of structural engineering, civil engineering and geotechnical engineering services. We pride ourselves on displaying our experience through our portfolio of landmark projects and long standing client relationships.

Our History

Over 30 Years Experience • A Legacy of Engineering Innovation

Walsh was founded in 1989 by Stephen Walsh with one clear goal in mind. To provide innovative, cutting edge solutions to construction challenges, with client satisfaction at the forefront at all times.

We have come very far in a short space of time, from our humble beginnings in our Rayne’s Park Office with 14 staff; to our offices at Butlers Wharf with 130 employees more than 30 years later. Among our first clients were Galliard Homes, Ballymore & Hollybrook Homes, who we maintain strong relationships with to this day.

Some of our heritage projects as structural and civil engineers include well known structures such as, The BBC HQ in White City, Fyffes HQ in Basingstoke, Westminster Hospital & Millennium Harbour.

Due to the reputation we acquired for providing practical design solutions, our clients have been able to confidently trust us with their most prestigious projects up to present day. This includes projects such as, The Stage in Shoreditch, Embassy Gardens in Nine Elms, & Tottenham Stadium – to view more of our Portfolio, click here.

We have always been driven by a desire to innovate; and due to this we were one of the first Engineering practice’s to use 3D non-linear finite element software, along with Building Information Modelling (BIM). We were also one of the first firms to engineer structural solutions with post-tensioned (PT) flat slab concrete.

Our desire to have a positive effect on society through our operations also saw us among the first firms to develop our own tool to greatly assist the efforts of our clients to reduce their carbon footprint. In 2014 we released our Embodied Carbon Assessment Tool, which takes into account all aspects of a project; and how this will affect the total output of embodied carbon.

In April 2022, Walsh opened a specialist geotechnical department, increasing the scope and capability of its civil and structural engineering excellence.

Today we continue to grow in numbers, strength & experience. Delivering award-winning designs & retaining close relationships with our clients. We are dedicated to remaining trusted Engineering partners in the built environment – now, and in the future.

Taking Sustainability Seriously

Sustainability is in our DNA and we have our own ambitious goals to achieve Net Zero as a business and with our designs. With innovative in-house monitoring tools, Walsh clients have seen on average reductions of 10-20% total embodied carbon, with some of our flagship work achieving 60-70% reductions compared with baseline figures.
