Convert a class 10a to class 1a
If you wish to convert a shed (Class 10a) to a dwelling (Class 1a) you must obtain a building permit. You may choose to engage a registered building surveyor for a certified application or complete an uncertified application.
All requirements of a normal building permit application still apply, but you will also be required to engage an engineer to assess the building's suitability for conversion to a Class 1a building.
