Builder has given me two options to choose from: Option 1: Main house backyard size: 87m2 Granny flat backyard size: 122m2 Option 2: Main house backyard size: 101.5m2 Granny flat backyard size: 107.5m2 The difference between option 1 and option 2 is largely due to setback. There is an easement at the rear of the property 2m wide. Option 2 sets the GF back 0.3m from the easement (2.3m from the rear fenceline) which means we have to go through DA approvals. Option 1 however meets the CDC rules and sets the GF 3m from the rear fenceline, so it can be approved via private certifier. From a rentability perspective, would the GF benefit from a bigger backyard. Would the main house's rentability decrease because of the smaller backyard? Is it worth going through DA to achieve a bigger backyard for the main house? Appreciate your opinions.
