The system will light up the sky in the city's financial district

The �26m Sentinel development by Kenmore Property Group will use LED lights to project each floor's colour.

The innovative illuminations will form part of the city council's Art in the City drive.

Specialists KJ Tait engineers provided technical expertise on the plan and the building will reveal its eye-catching colour by December 2004.

A tenant occupying the entire building could choose their corporate colours to be beamed into the sky.

Kenmore's Mary Galbraith said the project was taking office lighting in a different direction.

The lighting is being integrated into the very body of the building Mary Galbraith Kenmore

"The lighting is being integrated into the very body of the building so that the property will glow every evening and take the design of today's office properties onto a new level," she said.

"The technology has not previously been utilised in the UK and we believe it will attract considerable interest when the project is completed in December."

Gordon Murray, of architects gm+ad, said it wanted to integrate colour into the design of the exterior of the building.

"An evolutionary process, the coloured elements were initially conceived as a special glass," he said.

"However, this proved impractical, limiting the amount of light let into the building during the day and diminishing the colours come evening.

Architectural assets

"As a result, we moved to a lighting based design."

The city council has already used LED lighting to illuminate Glasgow's bridges.

Council leader Charles Gordon said: "Our lighting strategy for Glasgow has so far focused on using special lighting effects to highlight our best architectural assets as well as using lighting as an art form.

"The proposals for Sentinel support this strategy and we are very pleased a private developer has taken such an imaginative approach to the ongoing process of regeneration for Glasgow."
