Twin Creek Farms Estate is one example of the work of Caviness Landscape Design. (When Hugh Hefner’s infamous pool with grotto is not the most extravagant in the gallery of projects, you know these designers do some special work.) The vibrantly lit — with 32 custom light shows — Twin Creek Farms experience features a beach-style entry; grotto areas both wet and dry including a swim-up bar and a kitchen; waterfalls; dry-laid stonework; and patio with television and sound system.
