1 Lombard Street, 3rd Floor West, London
The key goal of the project at 1 Lombard Street, 3rd Floor West, was to deliver a high-quality, sustainable Cat A fit-out that modernized the space while aligning with BREEAM principles. The project sought to enhance energy efficiency, occupant comfort, and resource conservation, ensuring the space met the highest environmental and operational standards.
Located in the heart of London’s financial district, 1 Lombard Street is a historic building with a prestigious address. The third-floor West refurbishment was designed to blend modern functionality with the heritage of the site, integrating sustainability into every aspect of the fit-out.
Key features of the project included the installation of new sanitaryware and WCs with water-efficient fittings, the reuse of raised access floor tiles to minimize waste, and enhanced insulation for thermal and acoustic performance. The mechanical and electrical services were upgraded to improve operational efficiency, including the installation of FCUs and new metering systems that align with BREEAM RFO Ene 02 requirements. The project scored particularly highly in BREEAM Management Performance, demonstrating strong sustainability leadership. Water efficiency and energy monitoring were also standout categories, ensuring long-term environmental benefits and reduced operational costs.
One of the key learnings from the 1 Lombard Street, 3rd Floor West project was the importance of early-stage integration of sustainability strategies to meet BREEAM targets effectively. The team faced challenges in balancing modern sustainability requirements with the constraints of a heritage building, particularly in upgrading services without compromising the structural integrity or historical elements of the site.
Using BREEAM as a framework helped the team identify the most impactful strategies, such as optimizing insulation for both thermal and acoustic performance, upgrading metering systems to align with BREEAM RFO Ene 02 requirements, and specifying water-efficient fixtures to enhance resource conservation.
Collaboration was crucial in delivering maximum value. The architectural and MEP teams worked closely to ensure new installations met both performance and sustainability objectives. Repurposing raised access floor tiles reduced material waste, while enhanced window upgrades improved natural lighting, reducing reliance on artificial sources.
This project reinforced the value of a holistic design approach, where sustainability is embedded at every stage. These learnings are now being applied across other fit-outs to further improve BREEAM performance in future developments.
