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; we would still advise regretting for a certificate of lawfulness to get the approval from the council as the council will review all drawings and do background checks on the property in question. To obtain a certificate of lawfulness, it will take 8 weeks for a decision to be made. Then, once approved, register and submit the second double-storey side or rear extension design to the council under a householder's application. The new drawings will reflect the dormer loft design as existing, with a reference number showing the passed project being approved. This new second application should take no more than a week to be validated. The case officer will then make a judgement on the proposed double-storey side or rear extension being put forward interlinking with the dormer; now, if the design fits all planning policies, there should be no reason to get approval on the double side or rear extension on week 8, which is the decision day. Then, your builder will be able to build everything as a combined project. New drawings will need to be created to show the combined double-storey and loft conversion together, and registration to building control will need to happen for their team to review and approve the design. Engineering calculations will then need to be produced for the entire project to be also submitted to building control for checking and compliance. Using any private building control company is highly advisable as the council has a bad reputation in this area. This is the normal, practicable way, but in the real world, the council can make everyone's life hell by refusing the second application without any warning, so there are no guarantees.
