About the project
West Hendon is a major regeneration project in Northwest London that is transforming a post-war housing estate into a vibrant, mixed-tenure neighbourhood centred around the Welsh Harp Reservoir. The wider masterplan will deliver new homes, improved public spaces, enhanced pedestrian connections, and upgraded community facilities, creating a high-quality residential environment with strong links to the surrounding area.
Phase 3A is a key stage of the detailed redevelopment and comprises six residential blocks providing a mix of private and affordable homes, together with ground-floor retail units, podium landscaping, and basement car parking. The buildings range in height, with Block E2 rising to 26 storeys, Blocks E1, E3 and E4 at 9 storeys, and Blocks G1 and G2 at 7 storeys. Their arrangement has been carefully planned to frame key pedestrian routes and public spaces, while maximising views across the reservoir. The phase also delivers essential infrastructure and public realm, including landscaped podium decks, streets, and courtyard spaces that connect with earlier phases and help knit the wider development together.
Understanding the challenges
RHB were appointed to deliver the full mechanical and electrical design and coordination for Phase 3A. The combination of high-rise and mid-rise residential blocks constructed above shared one- and two-storey basement car parks created a complex servicing environment, demanding careful planning of riser locations, plant distribution, ventilation strategies, and drainage systems.
Close collaboration with the architect, fire consultants, and civil and structural engineers was essential to resolve competing spatial, regulatory, and operational requirements. Particular emphasis was placed on integrating services through the podium levels without compromising landscape quality or access, coordinating basement intake and plant areas to suit the construction sequence, and developing compliant fire and smoke control strategies for the tower and associated blocks. This structured, multidisciplinary approach resulted in a technically robust, buildable MEP design that fully supported the architectural and engineering vision for the development.
