What I find most satisfying is the variety that comes with working on diverse projects and the different challenges that they present. One project that stands out is the redevelopment of a large children’s hospital. The health trust wanted to modernize the facilities to meet the needs of modern clinical care, while keeping the hospital operational. This meant that a 1970s building would need to be replaced and I felt that to demolish it would be wasteful, as well as being difficult for the hospital to keep working. I was part of the Development Control Plan Review and led a study to consider partially demolishing the existing building and adding extra floors above it. I continued overseeing the project through to design and completion. In terms of the embodied carbon that we were able to save, I feel this was a forerunner to current day thinking. 

I mentioned that I’ve always been interested in the architecture and the history of buildings, and I particularly enjoy working with architects on the adaptive reuse of structures. I love working out how to reinvigorate a building for the future, to retrofit and, usually, to extend it, while also preserving its features. My very first job was to return the fire-damaged roof of a little Christopher Wren-designed church in London to its original form. A larger scheme that I’ve enjoyed more recently is a residential-led development of an Edwardian building in London. It features a very long retained façade as well as structural isolation bearings which help to deal with ground-borne vibration.

This involved some interesting Research & Development, and we succeeded in producing buildings of 12 and 13 storeys, the tallest of their type in the UK at the time. We also conducted testing and analysis and reviewed the technologies for a paper I co-wrote with the academic, Mark Lawson, entitled Modular Design for High-Rise Buildings, explaining how this type of construction could comply with code design standards.

With the 2008 recession, much of the innovation around modular work went on hold, it is now back on the agenda – and it’s not just volumetric modelling, but a wider approach to off-site construction. I now chair the WSP UK team focused on MMC and we are continuously learning from one another, whilst building a strong reputation for WSP as a leader in this.

An extreme challenge we constantly face is the design of deep basements in the highly congested ground under central London. We have to contend with the proximity of London Underground and other third-party infrastructure and we would not be able to accomplish this without the support of our excellent geotechnical team and their expertise in site investigations, modelling and monitoring of ground movement. For example, I collaborated with our geotechnical team on a 43-storey residential and hotel development adjoined to a refurbished Victorian building. It has a four-level basement, which contains a box-in-box construction for a ballroom and sits adjacent to busy London Underground lines.

The industry is waking up to the fact that we have a huge impact on climate change and the future of our planet in terms of embodied carbon, which means using our limited resources wisely. I’m not against new build – after all, great architecture adds to our enjoyment as human beings. But while we continue to build new, creative and interesting buildings, we also have a massive responsibility not only to build well, but to make use of our existing buildings and adapt them to change of use rather than thinking about demolition first.

I remember how, at the beginning of my career, everything was completely new, and just as I got comfortable with one aspect of the job, the next challenge would arrive to test me. It took around ten years until everything clicked into place. I would tell that young version of myself not to be daunted, but to embrace everything new that you learn. Eventually, it will all come together, and you will have a wealth of amazing experience to draw on, for a highly rewarding and enjoyable career.
