Morrisons has unveiled images of what its new West Watford store could look like following planning permission being granted last night.
The supermaket, which will be build on the site of the old Royal Mail depot in Ascot Road, will take a year to construct and will be completed by early 2014.
Last night Watford Borough Council's development control committee approved the plans for the store and its 400-space car park.
The company says it will create jobs for 300 people and Morrisons promised to work with JobCentre Plus to ensure that half the jobs will go to the long-term unemployed.
Richard Haynes, development executive at Morrisons, said: "We are delighted that the council’s development control committee has approved our applications.
"The new store is our first in the area and represents an additional store within the M25. We look forward to bringing our famous fresh food offer to Watford and to becoming an integral part of the town."
Watford Borough Council development control committee also approved outline plans to a new primary school to be built on the site.
A two-form of entry school is expected to be finished in time for the September 2015 intake, and provide places for 420 children, as well as a nursery for 60 under five-year-olds.
A masterplan also showed how the site could also house new homes, office space, retail and a hotel, as part of a wider redevelopment before the new Croxley Rail Link station opens in 2016.
