putting up fences after you buy new

don't know if this is a dumb question but if i was to buy a new house
(house and land package) and it didn't come fully fenced(or turfed back yard)can i claim the cost of one or both back in my tax.
It is a capital expense and so you will only be able to claim depreciation on it to reduce your tax and only then if it is an IP not your PPOR.
