I live opposite a motorbike showroom, and we get a lot of revving and throbbing at weekends, but I'm more or less used to it now, and they are mostly considerate. At least the other neighbours are nice and quiet, the noisiest things is the mowing, and the chickens over the back announcing they have laid an egg.
Re swimming pools, I have long hankered after my own pool, and found what I thought was the perfect solution. A positive flow pool in the garage! They are quite small, and have a current, so you can swim on the spot, and some can also be used as a jacuzzi.
DH vetoed the idea due to unreasonable things like cost, feasibility of water supply, drainage and the fact he wants to keep his car in the garage. But I think all of those objections are far outweighed by having my own secret health spa hidden in the garage. I love DH, but his practical engineers brain is frustrating to my flights of fancy.
