Transforming existing buildings through complex structural remodelling, retention and reuse to meet the demands of a changing built environment.

Send a brief

The built environment is evolving, and so are we. Alongside our market-leading demolition services, we have become a recognised specialist in structural remodelling and cut-and-carve projects, helping clients unlock greater value from existing assets through retention, adaptation and reuse. 

Whether a project requires complete removal, selective demolition, façade retention or major structural alterations, we provide engineering-led solutions that optimise programmes, reduce risk and support long-term sustainability objectives. 

The increasing focus on sustainability and embodied carbon reduction has driven significant growth in remodelling, refurbishment and structural retention schemes. 

Keltbray is a recognised specialist in complex remodelling projects, delivering engineering-led solutions that transform existing structures to meet modern occupier requirements. 

These projects often involve highly complex structural interventions, requiring meticulous planning, sequencing and engineering expertise to safely modify buildings whilst maintaining structural integrity throughout construction. 

  • “100 New Bridge Street embodies Helical’s ‘carbon friendly new build’ model, retaining as much of the existing building as possible while creating a building that meets the demands of todays occupiers’. Early engagement and collaboration with Keltbray, Mace and the wider project team has been key. Through the championing of circular economy principles, the site team have driven down carbon emissions and created significant social value.”
