Garden expenses

I have a very large garden which is perfectly fine for work, we have mainly lawn and some decking, swing set ride ons etc. I would like to fence some of my garden off directly outside the patio doors so it can be a smaller contained space for free flow when the weather is reasonable. I was thinking of getting artificial grass in this area to save having to move sand and water trays climbing cube slide etc to cut the grass. Would I be able to put the price of the fence and the artificial grass through my acounts as I certainly wouldnt be getting this done for any other reason than a safe early years area. Thank you.
