BLOOMBERG EUROPEAN HQ, LONDON
TILLOTSON DESIGN ASSOCIATES /
FOSTER + PARTNERS
The financial and media group Bloomberg’s European
headquarters, designed by Foster + Partners, is a
BREEAM Outstanding-rated development on 1.3ha
in the City of London. It provides around 100,000sqm
(1m-plus sq ft) of offices; three public spaces and
a pedestrianised retail arcade. ‘The deep-plan
interior spaces are naturally ventilated through a
“breathing” facade, while a top-lit atrium edged with
a spiralling ramp at the heart of the building ensures
a connected, healthy and creative environment,’ says
Norman Foster. Occupying a full city block, it brings
Bloomberg’s 4000 London-based employees under
one roof for the first time.
The site is divided by Bloomberg Arcade, with
restaurants and cafes at ground level, set back behind
an undulating facade under a covered colonnade.
The facades are defined by a deep structural
sandstone frame with inset geometric, vertical
bronze fins and serrated glass. The fins shade the
floor-to-ceiling glazing and vary in scale, pitch
and density across each elevation according to its
orientation and exposure to the sun.
Tillotson Design Associates’ lighting design includes
multiple, intricate layers of exterior lighting that give
the complex the appearance of being lit from within.
The perimeter lighting of the upper office floors uses
continuous, linear LED uplights recessed within the
interior base of each window surround, to create a
homogeneous spill of light on to the exterior surface.
The public realm around the building is topped with a
ribbon of crystalline fins, edge-lit with concealed LED
sources. Intermittently spaced accent lights with very
narrow-beam widths tilt out at a sharp angle to light
the surrounding pedestrian areas, while linear LEDs
with a range of optics, tucked away in the tops of the
bronze plinths, uplight the stone soffits above.
The main entrance is defined by a substantial porte
cochère and the reception lobby leads to the Vortex,
a double-height space created by three inclined,
sinuously curving, timber shells that form the ceiling
plane. At its centre is a new two-part specular
