I think you should consider at least 1.25" thickness for exterior paving for heavy traffic or min. 0.5" tiles for foot traffic only but of course decision is yours.

PirateFoxy - I haven't been ignoring your comments on the pool...I'm a bit undecided about whether the pool goes where it is or whether it goes lengthwise across the back of the yard. This placement gives us a 45x45 space of grass for the boys to throw a ball, kick a soccer ball, etc. The other way gives a 20x70 area. We think we all prefer a 45x45 space. The current placement provides for patio connecting through to outdoor living area and also to the kitchen...so no walking on grass. As it relates to access to the pool it will either be in/out of the kitchen or the outdoor living area. I think in spring/summer/fall during the day we would keep the big doors open between the dining area and the outdoor living area. With the bathroom in the new location if someone is wet and needs to use the bathroom they could go in through the garage and into the bathroom area. Or they could just dry off... On the first floor, the big room labeled Living/TV room will be an informal living room / family room. It may or may not have a tv (maybe a small one). It will be our comfortable living area. The basement will have a real TV room with a bigger TV for watching football or movies at night. It will also have a 4th bedroom suite, a gym, a wine cellar and an area for ping pong / foosball. Outdoor shower is a good idea. Haven't thought about that placement yet. Thanks for all your help and thoughts!!!

Katie32123-your cheery closet is just about the size of my storage room where my washer & dryer are. I have some storage area on both sides of the appliances but its very narrow & hard to get anything in or out & the hot water heater & freezer also share the space. Yes I have alot crammed in there but I just think its needs painting & a new arrangement which is the part that stops me dead in my tracks..but your yellow has given me inspiration.

Might depend on the fixture, but if you want even illumination, the fixtures should run end to end.
