10 Fenchurch Avenue
10 Fenchurch Avenue is a new mixed-use office development located in the heart of London’s insurance district. Designed by Eric Parry Architects, the development comprises of a seventeen storey building that includes 14 floors of office space from mezzanine to level 13.
From the tenth level, the building sets back with a crown type arrangement with further upper office floors plus a roof restaurant and publicly accessible roof garden above. The building also offers a four storey basement including; car, motorbike and bicycle parking on two levels with plant spread across three levels. Access to the car park is via two dedicated car lifts.
Waterman’s building services and environmental teams are working closely with Generali, Greycoat CORE, and Eric Parry Architects throughout.
The scheme’s basement has been designed around the requirement to keep the existing high street bank on the site in operation whilst demolition and construction works are taking place. The construction programme prioritises the requirement to build the new bank premises in order to facilitate the move into the new building and to allow demolition of the old bank building.
Due to the electrical load requirement the building was connected to London’s new 33kV electricity network infrastructure requiring two storey substations in the basement. The new supplies are delivered to provide N+1 resilience.
The existing public right of way passage of Hogarth Court has been replaced by a new passageway with a large central area, reminiscent in proportion of historic banking halls.
The upper office floors have a double skin passive façade with the outer pane including diachroic glass. This high performance façade significantly reduces solar gain in summer through motorised blinds whilst maximising the opportunity to benefit from useful daylight at appropriate times.
Energy efficient chillers are to be positioned in a recessed plant well, and carefully integrated with the landscaping to provide a visual and acoustic barrier.
The roof garden has been designed to include all the best aspects of a public space with the challenge to integrate building services and energy efficiency requirements. The design elements include a large water feature along the south perimeter. A combination of Wisteria trees and Pergola canopies growing high across the roof garden will contribute to the overall shading and zoning of the space. The roof garden will provide an area which allows a continuous walk around the perimeter and stunning views of the London skyline in all four directions.
Our sustainability team have been involved in the project since early 2011. Driven by the demands of Generali the project is now on track to achieve a BREEAM 2014 New Construction ‘Excellent’ rating. The team undertook feasibility studies to determine whether the original design proposals in accordance with BREEAM 2008 guidance could be uplifted to current standards. Workshops on the full range of sustainability disciplines have ensured that robust solutions are implemented for issues including materials specification, mechanical and electrical plant performance, consideration of future climate change conditions and inclusion of comprehensive sustainable transport solutions.
