Setbacks are defined by the local council and you should check with them regarding your block of land; however there are general rules of thumb regarding setback:

• Front minimum setback is 6 meters
• Side minimum setback for lower level is 1.5 meters. Side minimum setback for upper level is 2 meters
• For narrow block of lands, the garage can be built 200mm away from the side boundary
• Rear minimum setback for lower level is 1.5 meters. Rear minimum setback for upper level is 2 meters

Keep in mind your rooflines must be within the setback limits as well.

Depending on the type of roof you use, you can build up to the boundary so long as there is no gutter hanging over the boundary and that the sides of the carport are left open (batten screenings are an exception). However if you have a gutter running in line with the front boundary it is recommended that you provide at least 200mm clearance to ensure that the council will approve your carport.

It is possible to retain the existing roof depending on the scale of work being done which may save on cost. However it is best to consult your builder/ structural engineer about the feasibility of retaining the existing roof. Also consult them about both options before making and big decision especially in relation to structural issues.
