Simply put, a luxury development is not a luxury development without a swimming pool. Condo buyers may not use them, and the pools may drive monthly maintenance fees to ridiculous levels, but developers know that a private pool is an important marketing hook in the current high-stakes game of real estate development. These "lap pools" are supposed to be an exercise amenity, but for the most part they're sold as sexy playgrounds or relaxing getaways. The trend is so popular that it seems like every week we're posting renderings of a new development's private pool. And it got us thinking about which of these swimming holes cuts through the chlorine clutter and rises to the top. So, above is a photo gallery of our favorite new pools, ranked from 10 to 1. Many of the entries are renderings, which is why we're not calling these the "best." Who knows how these things will turn out? Instead, they are?for one reason or another?our favorites. Check it out, and let us know which ones we missed.
