SWINDON'S Cellular Opera-tions building is guaranteed to turn heads, and is also in demand from television directors.

This year, a number of TV companies from across the UK have visited the Peat-moor call centre to film.

Tiger Aspect, the producers of hit TV shows such as The Vicar of Dibley and Teachers, came to film a Channel 4 programme called Architecture of the Everyday', which will be screened ahead of the RIBA Sterling Prize Award for Architecture on 12 October 2002.

Cellular Operations was also visited by BBC researchers planning a two-part mini-series about a Swindon Call Centre, which will star the former East-Enders actress Tamzin Outhwaite.

Earlier this year, Former Millennium Dome Boss, PY Gerbeau visited Cellular to film a documentary for the Open University.

Now it is opening to the public as part of the Heritage Open Days.

Specially trained guides will be conducting free 30-minute tours on Saturday and Sunday.

Spokesman Roy Sayadian said: "Visitors will be shown a number of unique features, which have helped us to achieve the reputation of being one of the happiest workplaces in the UK.

"People will be able to experience for themselves what it feels like to walk within our trademark glass bubble which boasts spec-tacular views of Peatmoor Lagoon."

He said the building also boasts intriguing gadgets including lifts that arrive without a button being pressed; a water fountain that rises and falls with the lifts and a selection of theme toilets that have already won a prize in this year's Loo of the Year competition.

He said: "We have huge glass entrance doors powered by an aircraft hangar com-pressor.

"We also enjoy a venti-lation system that helps to avoid sick building syn-drome."
