The design of the accommodation
is to a "contemporary" Clerkenwell/Soho-type
finish, and involves fashionable design including exposed
brickwork, exposed cast iron columns, roof terraces,
wooden floors, circular staircase etc which appeal to
the Clerkenwell occupiers, all in an energy efficient
Allergy UK and healthy buildings International Ltd have
given their support to the project, thus making Redab,
and this building, the first company and building in
the UK to achieve The British Allergy Foundation's Seal
of Approval (Allergy UK).
Structure and Building Envelope
The development at 77-79 Farringdon Road consists of
a steel and concrete frame constructed building with
timber floors generally throughout. The external walls
are generally of brick and stone work. The main office
area will consist of 300-350mm raised access. There
are load bearing columns supporting each floor. The
upper floors have a timber mansard frame with zinc cladding.
The flat roof is to be strengthened to accommodate the
roof plant, which is to be concealed behind acoustic
A new entrance hall will be constructed on the Farringdon
Road frontage. It will be close to double height and
be fully DDA compliant. Benefiting from hard stone finishes
giving the building a strong identity. The entrance
hall will be of significant size and benefit from two
passenger lifts (one fire-fighter), serving all floors
and the roof level. Glass, slate and oak will be the
main materials used with white painted walls and ceilings.
Two new Otis motor room less electric passenger lifts
serve all floors throughout the building. The finishes
match the reception area and also have mirrored walls.
The lift car speed is 1m/s giving an estimated trip
time of approximately 35 seconds basement to roof. The
doors are 800mm wide and each lift is designed to carry
WC's, shower, and bike
A total of 23 new unisex toilets and disabled WC's are
provided throughout the building. The walls and floors
will be fully tiled and benefits from mirrors and sanitary
fixtures. A shower and bicycle parking will be located
at lower ground level.
An under floor air conditioning system designed by Protek
Flexible Office will be installed throughout the building
to give flexibility as well as "healthy air"
to the occupiers. Chilled ice storage cooling will produce
ice during the night for utilisation during the day
tariff. Up to 250kW-hours of cooling will be stored
in the banks. The ice melts during the day producing
cold water that will be used for cooling. From Autumn
to Spring "free" cooling will be used by running
only the dry coolers.
Protek's use of energy saving
complaints in its ZA units means that the building's
cooling/heating costs will be extremely low. The outdoor
air intake will be regulated by C02 sensors and these
units also include energy recovery technology.
Each of the office floors will benefit from full access
raised floors with a wooden finish. The walls will be
partly painted plaster and partly exposed bricks around
the windows to the street facades. Acoustic absorbents
are positioned in part of the ceiling to reduce noise
levels. The ceiling design will not be a traditional
suspended ceiling but will be of a style sympathetic
with the "fashionable" yet functional space
'Contemporary" suspended light fittings will be
