You need a business plan before you enter the catering and tourist industry at this time.
You should have a read of the County Development Plan and any sections that deal with your site and intended use(s) and in particular the definition of "Architectural Conservation Area".
Having familiarized yourself with that document, you then need to take competent professional advice from one or more of the following;
- The area planning officer
- A planning consultant
- A local architect experienced in obtaining planning permission in Architectural Conservation Areas.
Talking to the planner on the phone costs nothing.
Meeting him costs nothing either but you'd be well advised to go prepared and if you are having a poor response perhaps some advice from a planning consultant might open a way for you.
If you're serious about the project and there is any glimmer of light at the end of the tunnel after the initial conversation or a later one with a planning consultant, you may need to sit down with your architect and develop your ideas into sketch plan form.
You should then go the planner for a full pre-planning meeting, citing the planning consultant's comments and showing the architect's plans. Ideally one or both should accompany you if this is going to be a difficult meeting.
All this is money and you should outline your game plan to any players and get staged fee estimates before you issue instructions.
You can say that's a lot of trouble to get a house, but if you don't achieve a permission in the end, you're not at the races.
