Beneath the Surface: How Focus Building Solutions Redefined Basement Construction

When Focus Building Solutions took on the ambitious Goldhurst Terrace project, we knew it would be a challenge unlike any we had tackled before. The goal was clear but ambitious: to construct a basement beneath an existing property that was larger than the building’s own footprint. With spatial restrictions at every corner, our team would need to push the boundaries of traditional construction.

Typically, such projects require a clearance of at least three meters on all sides for machinery and access. At Goldhurst Terrace, however, we were dealing with just under one metre access on each side. This meant we had to completely rethink our approach to both underpinning the house and creating a functional, spacious basement. Undeterred, we dove into the project, committed to turning this seemingly impossible task into a reality.

Reinventing the Foundation Process

The usual route for underpinning involves heavy machinery and ample space to manoeuvre. Since neither of these conditions was met, we had to adapt. Our team crafted a pioneering methodology specifically for this site, which allowed us to support the house above a basement larger than its footprint – a solution that is rarely seen in standard industry practices. Underpinning typically involves strengthening a building’s foundation by extending its depth, either to access more supportive soil or to distribute the weight across a broader base. But the constrained space at Goldhurst Terrace meant that traditional underpinning methods like mass concrete or beam and base underpinning wouldn’t work here.

So, how did we do it?

Small Machines, Big Impact

Innovation became our best tool on this project. We set out to explore how we could adjust our machinery and methods to accommodate the space restrictions. This led us to experiment with smaller, lighter machinery that could fit through limited access points, something the standard construction toolkit rarely calls for. We brought in light diggers and dampers that could navigate through narrow spaces, allowing us to dig the basement in manageable phases and then underpin the structure gradually. This phase by phase underpinning process using light machinery was not just a workaround; it was an industry-leading approach. It allowed us to carefully excavate, support, and construct in a way that ensured the stability of the building above, without the need for the usual heavy-duty equipment. This tailored solution became a testament to the team’s technical expertise, resourcefulness, and dedication.

A Testament to Innovation and Dedication

Despite the hurdles, we successfully completed the project by leaning on innovative techniques and an unwavering commitment to quality and safety. Our team at Focus Building Solutions used advanced research and rigorous planning to adapt our processes to the constraints at hand, setting a new benchmark in how underpinnings can be achieved when typical conditions are far from ideal. This project didn’t just solve a unique challenge; it redefined our approach to construction under severe constraints and expanded the potential of what’s possible in underpinning and basement development. The Goldhurst Terrace project stands as a shining example of our philosophy: when you have the right expertise, ingenuity, and determination, even the most complex challenges can be transformed into opportunities for innovation. Focus Building Solutions is proud to have successfully completed this project, and we continue to bring the same commitment to every project we undertake, pushing the boundaries of construction one innovation at a time.
