Calls have been made to withdraw plans for 50 homes on an historic estate.

Shropshire councillors gave the nod for a controversial scheme to develop 50 new homes in the grounds of Brogyntyn Hall in Oswestry in November 2014.

But concerns have been raised over how the 50 new builds, plus the conversion of the Home Farm to create a further 11 homes, would fund the restoration of the Grade II-listed property which had fallen into disrepair.

Now Selattyn and Gobowen Parish Council will write to Shropshire Council calling on the plans to be withdrawn.

A motion put forward by Councillor Erica Morgan calls for the plans to be withdrawn over concerns about the original purchase price and how it impacts the enabling development.

Councillors voted to accept the motion and now parish clerk Jan Morgan-Birtles will write to Shropshire Council calling on the action to be taken.

She said: “The motion was accepted by the council and I will now be writing to Shropshire Council voicing that in due course.”

J Ross Developments, the company behind the scheme, said the new houses would fund the redevelopment of the hall itself.

But a document last year revealed that concerns were raised in an independent review over how the unitary authority was basing its calculations on the so-called ‘enabling development’ requirement.

Enabling developments are common – but English Heritage has issued strict guidance which includes the need for applicants to disclose the actual purchase price.

It also stresses enabling developments should be subject to the same degree of financial scrutiny as cash grants from public funds and all financial decisions made by public authorities.

Consultants Deloitte were asked to complete the assessment on behalf of Shropshire Council and English Heritage regarding Brogyntyn Hall. But they warned against using an estimated value after the applicants failed to disclose the actual market price.

In the document, Deloitte estimated the site to be worth £2 million – and on that basis backed the enabling development.

But new documents from the Land Registry have revealed the hall and grounds was bought for £672,500, throwing the need for the enabling development into question.

Although the report, which went before members of the North Shropshire Planning Committee, mentioned the Deloitte assessment, it failed to note the concerns over the calculations guidance and the lack of an actual purchase price.

Cllr Morgan’s motion says: “In light of the recent correspondence regarding the Brogyntyn Hall planning application, and the revelation of the original purchase price, it being almost three times less than the estimated figure used to calculate the conservation deficit and the need for an enabling development, it is motioned that the parish council requests that the enablement development of the 50 houses on the Brogyntyn Estate be withdrawn from the planning application, until the calculations used for permitting such an enabling development can be reviewed, and more accurate calculations can be made to establish a need, firstly, for an enabling development and secondly for the CIL exemption and affordable housing contribution relief decision.”

J Ross Developments has been asked to comment.
