Project Overview
Located in Bayswater, London, 13-19 Leinster Square is a prestigious refurbishment project that transformed an existing hotel into 15 exclusive lateral apartments, set behind a Grade II listed white stucco-fronted façade. The project includes the development of five townhouses and ten apartments, spread across five floors, including two newly constructed lower ground floors.
Proton Built Environment was engaged by Swiftline Engineering and Paragon to provide a comprehensive MEP design strategy, ensuring modern, efficient building services within the constraints of a listed heritage building.

Scope of Work
The project required the development and coordination of an intricate MEP system that respected the building’s historical features while providing cutting-edge functionality. Our responsibilities included:
-
Mechanical & Electrical Design: Complete design and coordination of heating, ventilation, domestic water services, and electrical systems, ensuring the infrastructure was capable of serving the modern residential units.
-
Basement, Riser & Roof Coordination: Detailed coordination of all MEP services across the basement, main riser, and roof spaces, managing the installation of services without compromising the building’s aesthetic and structural integrity.
-
Thermal Comfort Study: A detailed thermal comfort study was carried out to assess the building’s heat gain and loss, ensuring compliance with planning conditions and reducing the risk of overheating, a critical consideration in residential developments.
