The Project
Our experienced team led the transformation of The Lantern, 75 Hampstead Road into a cutting-edge, sustainable 7-storey mixed-use development. We played a key role in the complete redevelopment of the existing 1960s structure, carefully retaining 33% of the original concrete elements, including the foundations, basement, and ground floor slab, which enabled us to increase the site’s net lettable area by 46%.
One of our standout achievements was the creation of the striking five-storey-high ‘lantern’ window, visible from nearby Warren Street Underground Station. This feature, inspired by mid-century architecture, became a focal point of the building’s design. We also delivered a high-performance prefabricated, unitised façade with a sawtooth design that reduces solar gain and enhances the building’s sustainability credentials.
Internally, our team constructed a central atrium featuring a glass and glue-laminated timber roof, with biophilic design principles woven throughout the building. We incorporated natural materials such as European Oak in the lift lobbies, reception, and staircases, creating a light-filled, welcoming space. The atrium’s ‘forest floor’ provides a biophilic environment with trees, a rill water feature, and green walls, supporting occupant wellbeing.
We also worked to deliver top-tier amenities, including 252 cycle spaces, 34 showers, and 256 smart lockers, encouraging sustainable commuting. The ground floor includes vibrant retail units and a coffee bar, while 17 residential apartments were added, 70% of which are dual-aspect and 40% affordable, with some designated for short-term use by families of patients at nearby University College Hospital.
Sustainability was central to the project, with the integration of roof-mounted solar panels, heat-reclaim units that recover 60% of waste heat, and blue roofs that reduce rainwater runoff by over 50%. This award-winning project is a model for sustainable urban development, with lessons learned being used to create a material passport system for future developments. Through our dedicated efforts, we’ve helped deliver a building that sets a new standard in mixed-use, sustainable architecture.
Complex Substation Relocation
The existing building contained two UKPN substations, requiring the construction of three new substations before decommissioning the original ones. Our team successfully managed the relocation process without interrupting service, ensuring the new substations were operational and one of the original units remained as a backup, minimising potential risks and enhancing the building’s energy resilience.
Maximising Sustainability and Wellbeing
Balancing sustainability goals with the needs of a diverse mixed-use development while maintaining a tight schedule. We incorporated innovative, low-carbon technologies and natural materials, such as photovoltaic panels and high thermal performance systems, reducing the building’s carbon footprint. Thoughtful biophilic design elements, including green roofs, pocket gardens, and ample natural daylight, enhanced occupant wellbeing and fostered a productive, healthy environment.
Delivering The Lantern was a truly rewarding experience—blending innovative design, sustainability, and functionality to create a landmark space that will benefit the community for years to come.
