The Outline service always includes a measured survey, existing/proposed drawings for your project, OS planning maps and planning application fees. Following a consultation meeting and measured survey, the drawings for your project are drawn up and sent to you for review/comments. Any changes requested are made and the drawings resent to you for final approval and payment. Upon final approval and payment, the application for a 'Lawful Development Certificate' or 'Certificate of Lawfulness' is submitted to the local authority. If the project you have in mind does not fall under permitted development we would be pleased to talk with you about alternative architectural service options that HAS Studio offer...
