Garage door/space extra wide so garbage cans, kids not singing up cars.
We have a door from garage to yard and I made a change so that the garage door to basement lined up with that outside door instead of perpendicular. Great for hauling patio stuff up or down.
Utility sink in garage would have been nice, we'll do one in basement when finished.
Not having two shower heads in our master is a regret.
Pre plumbed basement and planned it out so electric, water, gas in the right places for the future.
We have water spigot on 2 corners of house, wish we had at least 3 now.
Have a good landscape person go over the outdoor plan, not just whoever the builder uses unless reviews show they are good.. Our edging was too tight to house for any decent plantings and mulch/rock setup not ideal. We've torn most out and redone in our 5 years. Shoveling rock sucks. Have also found spots of poor grade next to house.
We were supposed to have a garage drain but they missed putting it in. There's enough grade it hasn't been a problem.
