Seal House
Watkins Payne carried out the Independent Design Review role for Seal House, a commercial office development, located in central London.
This project involves the comprehensive redevelopment of a self-contained building, offering a total area of approximately 16,600 ft², with a distinctive private riverside garden that enhances the overall appeal and value of the property. The accommodation is distributed across five levels, with the lower ground floor featuring a newly designed amenity space intended to provide a variety of high-quality facilities for the building’s occupants.
The building has been meticulously refurbished to incorporate a range of sustainable features, targeting BREEAM Excellent and EPC A ratings to ensure the highest standards of environmental performance, energy efficiency, and sustainability. In addition to the eco-friendly goals, the building has been equipped with cutting-edge building services designed to improve overall comfort and reduce environmental impact. These include the installation of photovoltaic (PV) panels to harness solar energy and reduce reliance on non-renewable power sources. The HVAC system has been fully upgraded with modern, high efficiency units, complemented by HVRF (Hybrid Variable Refrigerant Flow) comfort cooling and space heating systems utilizing low GWP refrigerants, significantly lowering the building’s carbon footprint. The previous gas supply has been removed inline with the decarbonisation strategy for the building.
To further enhance the building’s functionality, a new duplex lift system has been installed, offering efficient vertical transportation between floors. This lift system includes an evacuation lift, ensuring the building is compliant with the latest standards and offering peace of mind for occupants in the event of an emergency. The integration of these advanced features demonstrates a clear commitment to sustainability, safety, and occupant well-being throughout the entire redevelopment process.
