The sundial consists of seventeen 8ft by 2ft elements, each element is orientated and rotated to represent a particular hour of day.

Entrance to the sundial is gained through the gap on the north side of the sundial.

The sundial design is essentially a modification on a multiple gnomon shadow plane sundial. Each element is constructed from two sheets of polished slate (steel or marble could also be used) with a thin slither of frosted glass sandwiched between them, each element is aligned with the analemma of each hour, when the sun is directly in line with the element it will illuminate the glass for approximately 3 minutes, signalling to the viewer what that the time is, when the time is between hours the viewer will be able to ascertain the time form the shadows created on the ground.

The middle vertical element represents 12 O clock midday.

The polished sides of each elements reflect the current weather and seasonal conditions.

Currently the design exists in computer model and small scale model form (made from acrylic perspex sheets), however it is my intention to one day build a full scale working sundial out of slate and glass.

Please contact me if you would like to fund or commission the design.
