An £11.6 million transformation delivering 45,000 sq. ft of modern workspace in the City of London.
We have transformed Alder Castle into a contemporary workspace and co-working destination with three new outdoor terraces and a reimagined double-height reception. The project involved the full removal of the building’s original glazed façade and the construction of an extended entrance formed with curved, frameless curtain walling. Inside, carefully detailed Cat A and Cat B refurbishments introduce warm materiality, improved natural light, and elevated finishes throughout. The result is a bright, modern workplace that pairs refined design with enhanced building performance.
The scheme combines Cat A workspace on the Ground, First and Second floors with a high-quality Cat B reception and co-working area. A new double-height entrance, formed through complex steelwork and curved glass installation, creates a striking sense of arrival. Levels 2, 3 and 4 now feature newly formed terraces, adding valuable outdoor space. Inside, reclaimed materials, sculpted timber linings, mesh bay ceilings and refined finishes elevate the workspace. The team delivered a bold, contemporary workplace that responds well to its historic setting.
