Louvered PoolhouseSimilar to the previous example is the aptly named Louvered Poolhouse by Ike Kligerman Barkley. While a flat roof is eschewed in favor of a gable form, in execution it is quite modern.
Pay attention to building codes. Generally, a pool house must be set a prescribed number of feet away from the pool, a figure that's often based on the depth of the water. Check your city or county's building codes to ensure that yours falls within the required guidelines.
