Drummond Street, London

The Project

The Drummond Street project involved the replacement of existing brick façades with a core focus on circularity and waste reduction. The primary sustainable innovation was the integration of crushed waste bricks from the original facade into the new bespoke exterior panels. This process significantly reduced the project’s embodied carbon by diverting substantial material from landfill and minimising the need for new, resource-intensive aggregates.
The new facade utilises Jesmonite, chosen for its sustainable properties, formed into complex panels for the building front and rear facades. A key technical challenge was casting these large multi toned panels (up to 5 different shades) requiring precise mix control and specialised casting techniques to prevent colours from bleeding and to maintain a high-quality finish and texture. This project demonstrates a successful fusion of advanced material technology and circular material reuse in a high-profile urban environment.

Scope of Works

• Circular Material Processing: Crushing and processing of salvaged facade bricks into suitable aggregate for reuse.
• Bespoke Jesmonite Panel Manufacture: Design, fabrication, and casting of large-format Jesmonite facade panels for the building front and rear facades.
• Sustainable Material Integration: Incorporating recycled crushed brick aggregate from the original facade into the new Jesmonite mix to reduce embodied carbon.
• Multi-toned Casting: Specialised casting techniques used to achieve distinct zones of different Jesmonite shades within a single mould, ensuring zero colour bleed and maintaining textural integrity.
• Facade Installation: Installation and sealing of the new bespoke Jesmonite facade system, including detailing and bespoke stainless-steel bracketry.
