Wedgewood advises that you consult your Local Planning Authority to check whether planning permission for your building project is needed. Some outbuildings and extensions do not actually require planning permission as they can be classed as ‘Permitted Development’ so it is worth investigating what sizes and other criteria are eligible as this could save a considerable amount of money.
Wedgewood can put you in touch with a very well respected, experienced planning consultant and firm of architects to advise you on this part of the process if you need.
