This one started with a yard full of overgrown trees and bare dirt - nothing close to what it became. We brought in the equipment, cleared the site, and started excavating for a 3,500-gallon koi pond from scratch. Every cubic foot of soil removed was intentional. The shape, the depth, the shelf lines - all planned before the first rock ever hit the ground.

The foundation of a healthy koi pond is what you never see. That means proper filtration, strong circulation, and aeration built into the system from day one. We installed a basin filtration vault and ran the plumbing before any of the decorative work began. Getting that right early is what separates a pond that stays clear from one that turns green every other week.

Stone placement came next. We work with natural boulders and gravel - not prefab kits - and each rock gets positioned by hand and by machine to create a natural edge that looks like it always belonged there. The waterfall feature was built into the design to keep water moving constantly, which also helps oxygenate the pond for the koi.

Once filled, the water settled clear and the fish took to it immediately. Multiple koi are already swimming freely and visibly healthy. The finished pond sits alongside a composite deck that extends out over the water, giving the homeowner a spot to sit right above the surface. At night, the underwater lighting turns the whole thing into something worth staying outside for.

A build like this takes real planning, a full crew, and the right sequencing of work - from tree removal to excavation to liner installation to rock work to final planting. We do it all under one roof, which makes the process a lot smoother for the homeowner and the end result a lot more cohesive.
