DISCOUNT PLANS LTD

Design one is the loft conversion, as you don't need planning permission for the loft conversion as it comes under permitted development, ignore the registration to the council for a certificate of lawfulness and submit the loft design directly to Building control. It is highly advisable to use any private building control company as the council have a bad reputation in this area. A typical loft conversion should take around 4 to 6 weeks to be completed on the build stage so this is all about timing. Submit the second double storey side extension design to the council under a householders application. This application should take no more than a week to be validated. A further 6 weeks is when to expect a visit from the case officer, that's when your builders have done a great job in completing your loft, gable wall and dormer just as the drawings are. The case officer will then make a judgement on the proposed double storey side extension being put forward, now if the design fits all planning policy there should be no reason to get an approval on the side extension on week 8 which is decision day. Your builders will be still working on site around that time anyway and then ll be able to start on the side extension with no major time breaks waiting for council responses. This is the normal practicable way but in a real world the council can make everyone's life hell in refusing the application without any warning setting back the build by another 8 - 10 weeks to get a new design over to them and start the whole process again waiting to get an approval.
