Filing units providing ample storage, while not obstructing sightlines, have been supplied by steel storage furniture manufacturer Bisley for the new London headquarters of one of the world`s biggest accountancy firms. They play a key role in creating a flexible open-plan working environment for BDO Stoy Hayward. The bespoke units, finished in white to match workstation leg frames, were specified by office design, fit-out and furniture specialist 3Sphere, as part of a £2m contract to provide and install more than 1,500 workstations with storage and seating areas.The Bisley LateralFile filing units were designed to be exactly tall enough - at just over 43.3" - to house three levels of A4 filing, while remaining sufficiently low to retain sightlines between seated employees. "Nearly 1700 units were specified, chosen for their superior quality, level of finish and detailing," explains Sarah Trown, Account Director at Bisley "They help to maximise the feeling of space in BDO`s new offices, while aiding communication between staff."Additional special features include special 180-degree hinges that allow doors to fold right back against adjacent units, keeping routes through the workspace free from obstruction. A similar number of pedestal units were also supplied, plus a number of custom-sized locker units positioned against walls.Designed by bennett interior design, the new London headquarters are located in a landmark building at 55 Baker Street, formerly the head office of Marks and Spencer and recently refurbished by architect MAKE. For BDO Stoy Hayward, it represents a radical change in working practices, moving from cellular office spaces to a totally open-plan and flexible environment. The filing cabinets help to provide some subdivision of the expansive open plan floor plates, with a layout optimised for team working.Furniture installation by 3Sphere was carefully phased and a key requirement was punctual `just in time` delivery of product from Bisley.
