Roof repairs costing as much as £300,000 are the latest steps being taken to rejuvenate Barnstaple Pannier Market.
Owner North Devon Council is working on a plan to repair the leaking roof of the Grade II-listed building.
The repairs are part of a number of improvements the council has earmarked to improve the market building.
It has already replaced broken skylights at a cost of £15,000, and has plans to install new toilets inside.
North Devon Council leader Des Brailey said: “The pannier market is our building, it’s listed and it’s an important part of Barnstaple.
“The roof could cost anywhere from £200,000 to £300,000. We have leaks and we need to address that before other things.
“We also want to reintroduce toilets in the Pannier Market itself. If we it close off at night but have a function we would need toilets inside.
“Market traders are keen for this and we want to help them as they do so much to support it.”
The repairs and improvements come after new measures to protect it from anti-social behaviour were introduced earlier this year.
The building has been protected by a Public Space Protection Order (PSPO) since February, and has been shut at 6pm each evening before reopening at 5am the next morning.
The PSPO was hailed as good news for traders, who were being met with mess from the night before including vomit, drugs paraphernalia and broken glass when setting up their stalls in the morning.
Councillor Brailey said there had been a noticeable improvement six months after the PSPO’s introduction.
He said: “We’ve noticed a vast difference and I’ve had no adverse criticism from the general public.
“There’s been a tremendous change because clearly we don’t have the vandalism that we had before.
“We needed to replace all the skylight windows because they were being smashed and broken – that’s gone away.
“When we move towards the Christmas period we will be able to decorate the place and leave them there and know they will be there the next day, whereas before they would have been destroyed.”
