We are applying for a householder planning permission-but in a conservation area.We want to install a garden lodge [also can be used as a kids playhouse].We have submitted a simple plan but have now been told we need a 'design and access statement'.Can we do this ourselves or do we need to pay someone to do this?.Bearing in mind we've already paid the local authority and streetwise [for maps] we are starting to think this is all to much just to install a glorified garden shed!.Can anyone advise?
