It’s the last week of summer, a perfect time to be staring into the hypnotic blue waters of a pool. To that end, we bring you the second installment of our pool extravaganza (see part 1 here), brimming with cool pools and the homes that adorn them. With styles that range from lavish to low-key, in regions around the country, ideas abound for projects of all kinds. So dive on in. The water’s nice.
