Structural sense
The use of CLT for all new elements of construction was informed by several factors. The lightweight nature of CLT generally enables foundations to be designed smaller and cheaper. At 142 Bermondsey Street it entirely removed the need to dig new foundations by minimising additional loads onto the existing footings. “The building's age meant there was a very limited capacity for extra loading on the foundations, which required a lightweight construction solution,” says Hampson.
In addition, the property is located in an
area of Archaeological Interest close to a riverside and any excavation work would have increased the risk of uncovering relics, potentially leading to site closures while archaeological work was completed. “Previously, we had carried out a design and build project nearby where Roman sandals were uncovered during excavation and that whole section of the project had to

be closed down for six months. We were quite conscious of those sorts of issues on Bermondsey Street and tried to minimise any groundwork,” adds Hampson. Utilising CLT made logistical sense as lifting prefabricated panels into position quickly by crane reduced construction time to just two and a half weeks, and with limited space for deliveries, it minimised disruption and the need for road closures. Construction was further simplified by limiting the need for wet trades like plasterers and painters. In addition, the precision-engineered airtight design helped upgrade the building’s insulation standards and thermal performance, which were very poor.
