Lighting Design: CHAPMAN BATHURST Architect: MCM ARCHITECTURE


Chapman Bathurst has completed an understated yet distinct lighting scheme at a top London law firm’s office building.

Leading UK law firm, Addleshaw Goddard has relocated its London office headquarters to the architecturally iconic Milton Gate in the City of London. Ranked seventh in the UK with regard to the number of FTSE 100 clients, they wanted to create a modern and sophisticated space to reflect their position and illustrate to clients and staff their prestigious status as a legal practice.

Chapman Bathurst specialist lighting, headed by Chris Peach, was appointed to develop a lighting scheme that would create an understated but distinct scheme that reflected the Addleshaw Goddard brand. This provided an opportunity to create innovative and stylish lighting within an office environment, the brief was clear from the outset: “The design should ‘dare to be different’,” Richard Oakes, the Business Development Director stated.

Working alongside MCM Architecture, Chapman Bathurst developed a concept that created links between floors to provide clients with a seamless journey through the building and introduced a number of bespoke lighting solutions developed to create visual impact and enhance the architectural detailing and finishes of the space.

Upon entering the central atrium, the main feature is a large cylindrical meeting pod on the first floor which is edge lit by low voltage cold cathode supplied by ACDC Lighting. The design intent was to create an impression of geometric shapes penetrating through the floor and creating a vertical connection between the levels. The detail is enhanced with the ceiling on the ground floor by introducing a 6m diameter Barrisol stretch fabric ceiling to the underside of the feature, providing diffused light to the soft informal breakout area below. Working closely with MCM Architecture and Structural engineers, Whitby Bird ensured that the feature created a sense of wonder and the illusion of the pod ‘falling through the floor’.

Linking the ground and first floors was an important factor in the design; a staff café is sited near the main entrance to create the sense of a relaxed and informal environment, unusual in the often formal environments usually associated with law firms.

The rear of the café has a large feature wall formed of full height vertical slats which were illuminated with wall washers, supplied by ERCO. This is further enhanced by continuing the linear detailing on to the ceiling and introducing linear slot lights (supplied by Zumtobel) of varying length to light the soft seating area. The linear slatted feature is mirrored with an eight metre high LED wall using back lighting to illuminate crushed recycled glass panels supplied by Greenhouse Effect.

OSRAM’s LINEARlight POWER Flex LEDs provide an even wash of light along the length of the feature while illuminating the feature stair case linking the two floors. Mock ups were undertaken to ensure that the LED solution was visually stunning and maintainable.

LEDs are also used within the corridor areas. Full height glass partitioning was edge lit from top and bottom using 174 m of Tryka linear LEDs supplied by Edward Wray Lighting positioned to avoid dark spots towards the centre of the wall. Introducing a 6mm sheet of plexiglass in-between the inner wall and outer glass wall and with the LED mounted directly underneath, provided the throw of light required to achieve a run of light along the full length of the glass. Numerous site trials were carried out with regard to beam angle to see what effect each option had on the glass, and a 6º beam angle was found to give the best throw and wash of light. This is offset with a continuous cove light detail to give life to the corridor.

Kreon supplied the Down Inline luminaire system with combined linear T5 fluorescent downlights and low voltage downlights providing Addleshaw Goddard with the ability to transform the meeting room from a bright well lit meeting space into a more informal space which could be used for evening functions or dining.

Addleshaw Goddard wanted to provide a number of rooms which could be used specifically for dining. MCM Architecture created a series of rooms with their own individual identity, introducing high quality fabric wall covering and furniture. Chapman Bathurst added to the boutique feel of the rooms by giving each room its own feature pendant. Opulent pendants from Brand Van Egmond, Artemide and Bocci provide an element of warmth and style not normally found in an office environment.

Within the ground floor restaurant, the lighting takes into account the multi use of the space and is divided into contemporary open plan seating and intimate high backed banquet style seating. A combination of striking angular pendants from DAB are installed over the banquet seating and an integrated linear Selux M100 slot light in the bespoke wooden slated ceiling is used in the open plan seating area. These two areas were split by introducing a random array of fluorescent stick lights (supplied by Waldmann lighting), which were suspended in varying angles to provide a web of lighting to link the spaces together.

On the general office floor the existing recessed modular downlights are retained but enhanced by introducing wallwashing to provide addditional vertical illumination. Addleshaw Goddard has moved from a mainly cellular office environment to an open plan office arrangement. This presented additional challenges of how to provide the staff with flexibility as previously they had local lighting control when in a cellular office. This was resolved using a Delmatic lighting control system to allow zoning of the lighting into small groups and the use of universal PIR sensors to achieve switching and daylight linking within the office floors. Local lighting control and scene setting is provided within the smaller meeting rooms and video conference rooms.

Jon Race, the Project Director of MCM Architecture sums up the success of the scheme; “Creative lighting solutions were always going to be fundamental to the success of the design; Chapman Bathurst really understood the brief and delivered”.
