The Vision

When award winning architectural practice EPR Architects, sought to create a new home for their London studio, they envisioned a space that exemplified sustainability, health, and cutting-edge design. Known as All Saints, the project centred on a sympathetic restoration of a structure originally constructed in 1875, where it was employed as an orphanage, a hospital and then as an archive for the Imperial War Museum. EPR’s vision aimed to retain the building’s original envelope while expanding its gross internal area (GIA) by 3,500 square feet, blending modern innovation with heritage preservation. The result would be a state-of-the-art, sustainable headquarters that supports collaboration, creativity, and the wellbeing of staff and clients.

Our Contribution

Hilson Moran was appointed to deliver a comprehensive suite of environmental, sustainability and engineering services, aligning with EPR’s detailed project brief. Our team provided expertise in mechanical, electrical, and MEP design, as well as consulting on sustainability, acoustics, security, fire strategy and air quality.

Initially, the design aimed for natural ventilation. However, detailed analyses of local air quality, acoustic conditions, and dynamic thermal performance highlighted the need for a hybrid solution. We introduced a mixed-mode peak looping cooling system that allows the building to operate in natural ventilation mode for a significant portion of the year, balancing energy efficiency and year-round thermal comfort.

Design for people

Central to the project was the creation of an environment that prioritizes the health, comfort, and wellbeing of its occupants. By targeting BREEAM credits Hea 05 and Pol 05, we ensured the building meets high standards for air quality, acoustic performance, and visual comfort, with the project achieving BREEAM excellent.

The building’s internal acoustic environment was meticulously modeled to enhance comfort in studio areas, meeting rooms, and office hubs. Existing timber joist floors with lath and plaster ceilings posed challenges, especially in isolating sound from noisy spaces such as architectural model workshops. We implemented bespoke solutions, including adding mass and isolated layers to floor constructions and acoustically controlling mechanical services.

Lighting design also played a vital role, with precision-engineered solutions tailored to support productivity, collaboration, and creativity in various workspaces. Our efforts ensured that the design not only meets functional requirements but also enhances the overall user experience.

Design for the planet

The All Saints redevelopment reflects a commitment to sustainability, both in reducing operational energy and embodied carbon. Our sustainability measures, including the hybrid cooling system and acoustic solutions, align with the values shared by EPR Architects and Hilson Moran, fostering a space that balances environmental responsibility with design innovation – enabling the building to be Net Zero Carbon in operation.

The collaborative effort across our Manchester, Farnborough, and London offices, facilitated by advanced virtual tools and acoustic modeling software, ensured seamless project delivery. Together, we have helped deliver a vibrant, sustainable, and innovative workplace for the long term.
