Our clients were referred to us by local Architects, Russell-Hughes of Anglesey. They had secured permission for an extension to a dwelling, but this had included a condition for a Management Plan to be submitted for a shared Septic Tank. However, the septic tank did not belong to our clients, although they had full rights to use the facility. Neighbour objections were proving a barrier and we sought to negotiate with the LPA that the condition was, under the circumstances, unreasonable. After a great deal of deliberation an application to delete that condition was successful and finally the clients could proceed to build their extension without the unworkable and overly restrictive condition. All conditions on planning approvals must meet six tests, if they fail just one of those tests then they are deemed unreasonable and should be removed.
