Design Requirements and Fee Guide
The first step involves working with an architect or design professional to create some visual layouts and designs for your planned extension or renovation.
Basic Planning Drawings
If the required design for the project is relatively straight forward then it may be most economical to select basic planning drawings to be made up. These would be used to detail the general size and external appearance of the proposed structures and help gain planning permission from the local authority. These would give only basic detailing of internal layouts and generally any special requirement regarding internal detailing and finishes would be left for you to specify to your builder.
Typical cost for this level of service would be around £400 - £1000.
