Customers could soon be shopping at a Tesco store that has doubled in size if the supermarket chain gets its way.
Retail bosses are to submit plans to Harrow Council next month to enlarge the Station Road store - which opened in 1992 and is one of the busiest in London - by adding a level above the current ground floor and within the existing roofspace.
This new top floor would house an increased range of non-grocery products such as clothes, homeware, white goods and electrical appliances while food would be found on a re-jigged ground floor.
In addition, Tesco proposes to build a second deck of parking over a section of the existing car park to increase its capacity from 386 to 620 cars, and there would be moving walkways linking the car park to each floor.
James Wiggam, Tesco's corporate affairs manager, said: "The store is very busy but it's not offering the customers what they want.
"Customers have been saying that they have to go to Tesco Watford for their non-food shop. This would provide the offer that people have been asking us for.
"Potentially, we could have the extension open by Christmas 2009."
He said the expanded store would create 200 extra jobs and that modern construction techniques mean three-quarters of the supermarket could remain open during building.
Similarly, the car park would not have to be shut while the extra spaces were built.
Mr Wiggam said 1,000 shoppers visited an exhibition on the proposal held outside the store two weeks ago.
He added: "Ninety per cent were very much in favour of the plans."
Brian Lanning, 75, of Francis Road, Harrow, said: "I think it's a good scheme, although obviously there will be potentially problems with traffic, if you have got more car parking and it's going to be that much busier.
"From a shopper's point of view and what will be on offer there, I would be in favour of it.
"The suggestion is it would be in step with the regeneration of Harrow, if some of the proposed developments in the town centre area take place, and many of us would be greatful for those improvements and by offering more parking spaces it may help improve the town centre."
