THE HUFFINGTON POST
When one of Hidden Hills' most photographed compounds needed water worthy of the architecture, the work was ours: a multi-level lagoon, grotto bar, swim-up cave, and waterfalls engineered to anchor the entire estate.
It's the kind of project we've quietly delivered across four decades, for clients who expect the backyard to be the best room in the house.

Concepts that solve the site before a shovel touches the ground. Infinity edges, acrylic walls, glass tile, fire and water.

Gunite construction engineered for hillsides and impossible lots. Four decades of structures that don't move.
Explore Build
Hand-carved artificial rock, waterfalls, and grottos, plus full transformations of dated pools into modern showpieces.

Our most recent honor: a national Gold Award for a project that cost over $1M and took more than a year to build. It meant retaining a steep hillside, then carving in a 40-foot water slide, cascading waterfalls, a shallow children's pool, a Baja ledge, and an infinity edge on both pool and spa.
The kind of brief most builders walk away from. The kind we live for.
A pool is the easy part. The reason an estate water environment costs what it does is everything underneath it: caissons drilled into unstable hillside, hand-sculpted gunite rockwork, structural engineering that has to outlast the house. Here is one build, start to finish.



"His rockwork is simply the most realistic in the industry, and his water environments the most impressive. Ultimate Water Creations is a first-class design/build firm."
"I was referred by one of the top designers in Hollywood. Mr. Goldstone designed the most spectacular pool with waterfalls I've ever seen, and it came out even better than on paper. Truly an artist."
"A complex job: multiple waterfalls, a pool, a jacuzzi and a cave grotto. The finished product is absolutely stunning, a lush tropical paradise that never fails to floor my guests. UWC is the only choice."
"I wish I had called Don first. After a false start with another company, Don made the whole process easy, his own team of rock craftsmen, his eye for the whole backyard. He truly loves what he does."
"Don created paradise in our backyard. Fifteen years later, it still feels like a tropical island vacation. Thank you, Don, for your vision and creativity."
"Once you see his work, you'll be unable to hire anyone else. As Picasso was to painting, Don is to pools. If you can dream it, he can build it, and it will be more beautiful than anything you could hope for."
