The clock tower at the heart of the development is created as a response to the industrial history of the area. The screen-printed glass cladding features images of industrial artefacts and processes specific to Kirkstall.

Each visual component of the clock mechanism is created from photographs of surrounding industrial elements: the pendulum – a forge-made vehicle axle, the clock face – the original Thrift Stores clock. The clock tower itself is wrapped in an image of a woollen spool, reflecting the blanket making and textile fulling activities carried out nearby.

JPLD were appointed by the Artist and creator of the tower, Kirsty Brooks, to develop a subtle lighting scheme which emphasized the elements described in the narrative while helping to establish the piece against a visually busy backdrop.

The clock face lighting is tuned to the daylight ambient level to ensure it is “comfortable” to view regardless of the time of day.

In appreciation of the industrious energy of the site and the people who occupied it the internal tower lighting is subtly changed to loosely reflect or respond to our natural circadian body rhythm requirements; cooler white light in the morning with a blue light fade on the hour moving through a red fade at midday through to a warmer white into the afternoon.

All the time subtly backlighting the stunning glass work by Kirsty & bringing the story to life, giving us different views & aspects depending on the light passing through, be it, natural or artificial.

The sound and rhythm of these processes and machinery provided an ever-present backdrop to the lives of workers and residents of Kirkstall. The clock tower reflects this rich history providing a visual link to the past.

The design and treatment of the glass was adapted in conjunction with JPLD’s lighting concept to maximise the light transmission and diffusion as well as the concealing of the luminaires & controls.

A simple yet robust scheme was created using RGBW linear luminaires to achieve the internal lighting and back lighting of the main glass, with a dimmable LED sheet solution through a semi-opaque diffuser used to backlight the two clock faces.

The whole system is programmed & controlled via a basic Pharos control unit housed in an enclosure in the base with a daylight sensor on top of the tower to monitor changes in ambient light level.
