The future of a busy garden centre in Twyford could be in doubt after it was served with enforcement notices for 15 separate breaches of planning permission.

Hare Hatch Sheeplands bosses have been given 18 months to get their house in order by Wokingham Borough Council.

The council said the long list of unauthorised building work was discovered as it prepared to defend refusing a £2m 'masterplan' to revamp the site in London Road.

The centre had launched an appeal against the decision which was due to be heard by the planning inspectorate last month.

The appeal hearing has now been postponed in light of the action taken by the council. The enforcement notices were served in October.

Garden centre owner Rob Scott said: "Should the enforcement notices be upheld, it would have an extremely serious and detrimental impact on our business."

But he added the centre is co-operating with the council and is confident a 'compromise' can be reached.

WBC said Hare Hatch Sheeplands only has permission for use as a nursery selling plants.

It says the catalogue of unauthorised work includes use of the land for display and sale of conservatories, use of greenhouses as an extension for the cafe and child's play area, use of an events area, parking and storage of vehicles, plant and waste, as well as use of the land as a garden centre.

A council spokeswoman said: "The 18-month time period is longer than usual.

"We have taken into account the difficulties of ceasing use, removing structures, potential difficulty for business, potential loss of employment and time to allow for discussions with the nursery to meet a negotiated solution."

She added: "We are still hopeful that a solution can be found."

The centre's revamp plans, which took more than two years to create, were rejected by the council in December 2011 over concerns about the greenbelt and the centre drawing trade away from Twyford.
