Daylighting: Natural Light in Architecture

Jubilee Line Extension ^ Stratford Wilkinson Eyre

The situation here is entirely different. It is an
‘above ground’ station, in which passengers
enter the trains which run inside the building
at the same level as the ticket office.

passengers to walk above the trains along the
rear of the hall.
The daylighting problem was solved more
by the nature of the structure, since this in
itself ensured a building of sufficient height,

more akin to a sports hall, with its large areas

of high level glazing around all sides of the

building. The final solution, with its solid roof

and large side windows, provides a well daylit

space where, during the day, there is no need

for artificial lighting any more than there

would be on an open platform.

The curved soffit to the underside of the

roof was designed in collaboration with the

UCL Laboratories as a reflecting light surface

to bounce light down into the concourse

space. This has been achieved by the design of

a purpose made aluminium extrusion,

perforated for acoustic purposes.

To ensure that the ceiling does not appear

dark in contrast, it is uplit by artificial lighting

from specially designed uplighters mounted on

the maintenance gantry at low level. These

throw light up to the ceiling and provide an

even intensity of light in the concourse.
