Sometimes referred to as a “lagoon-style” or “natural” pool, this refers to a design style that avoids straight lines, using sweeping curves and nontraditional shapes instead. If you want a natural-looking swimming pool, then you will want to combine a free-form shape with any or all of the following elements:

• Natural rock or stone built-in at various places around the pool
• A natural rock or flagstone perimeter/coping
• A rock or flagstone deck, or stamped concrete with a “natural rock” pattern.
• Extensive use of plants around the pool.

Grottos and jump-rocks are natural additions to a natural/free-form pool.
