Yep, that does it, w/out the pool, you’ll spend ~7/8%. Hiring a landscape designer will probably cost you a few grand more too. I doubt most people hire landscape designers, so if you buy resale, you’ll have to deal w/ landscape that’s not designed by a designer. It’ll cost you more to rip it up and put in new one (designed by a designer). 3600 sq-ft house probably have a foot print of around 2000-2200 sq-ft, then the front hard & drive way takes another 2500-3500 sq-ft, so your back yard is roughly about 1300-2500 sq-ft.
