The 2017 programme is now past. We will be launching the 2018 programme on 21st August.
EMEA Headquarters for Asian-based investment bank, Nomura designed by Fletcher Priest Architects. Currently one of the largest single lettings in the City of London
The building has 546,000 sq ft of net space over 11 floors of technologically advanced facilities. The 20,000 sq ft roof terrace overlooking the Thames is the largest in the City, allowing building users to enjoy the riverside setting views. High-level sedum roofs encourage wildlife including the resident bee colony.
This site has always had an important place in the history of the Thames located between Cannon Street station and London Bridge fronting the river. The northern edge is on the line of the former Roman wharf, and the 'Steelyard' under Cannon Street station was a German Hanseatic trading post, the largest medieval trading post in Britain.
Formerly known as Watermark Place, 1 Angel Lane replaces the redundant Mondial House, an early 1970s ziggurat design commissioned by the Post Office as a bomb proof telephone exchange. Housing giant generators in the basement, evidenced by the huge cooling cubes on the roof of the building, to power the building in the event of an enemy attack during the cold war. The building stands on a plinth 5.2m above sea level to reduce the risk of flooding from the Thames.
The pixelated façade has been created by taking a photograph of rippling water and running it through several Photoshop filters to create a dot-matrix interlayer that changes the appearance of the building and also provide solar shading.
The rotating timber louvres cladding the south-east building protect it from sunlight. The two riverside pavilions have curved forms, timber sunshades and roof gardens and are articulated to be separate structures, although part of a single composition. The fifth and sixth storeys step back to provide views from across the river to St Paul’s Cathedral.
The entrance and reception area contain a two-storey transfer truss supporting the building over the length of its eastern façade. Raked steel columns encased within an elliptical concrete skin support the truss. The columns are founded on the retained basement raft slab below. A linear atrium, inside the building, points towards the river with an 18m-deep space on either side, with bridges and glass elevators. The huge coffee table drums on the ground floor serve as displacement air inputs.
Formerly Angel Passage, Angel Lane has been widened and pedestrianised, encouraging its use as a walkway. The riverside blocks have been designed at an angle to catch sunlight, forming the largest south-facing public riverside space in the city between the Palace of Westminster and the Tower of London.
Sustainability was high on the architect’s agenda designing the building, to achieve a low carbon footprint. The building reused one third of the existing structure and eventually reduced the waste resulted from the demolitions. Moreover, 95 per cent of all demolition materials used in the construction was recycled. The existing foundations were supplemented by new piles and pile caps and organic paints used on the walls.
Some of the sustainable measures include passive double-skin ventilated façades, a five-storey brise-soleil structure and high performance argon filled glazing for solar gain control.
Green roofs have been incorporated into the design for rainwater attenuation and to support ecology and improve the efficiency of the building’s thermal envelope.
800 msq of photovoltaic panels at roof level provide renewable energy equal to 50kW peak electrical output.
Rainwater collection tanks installed in the basement are used to collect harvested rain water from the roofs. A grey-water recycling facility collects waste water from the basins, filters, treats and recycles it for toilet flushing. The cladding has been designed to exceed the minimum requirements as set by the new part L2 regulations by almost 20 per cent to 25 per cent.
