Agricultural Barn Development Advice

Got a barn and not sure what to do with it?

If you’ve got an agricultural or former agricultural barn, there’s potential to convert it to residential use (Class Q) or flexible commercial space (Class R) using permitted development rights.

These flexible options have specific criteria that need to be met, so care is needed to  ensure all of the requirements are observed.

At Laurence Associates, with our team of planners, architects and landscape architects we are well placed to advise you on which option would work best for your site.
