What's built in

Details that separate
good work from great.

Four disciplines · One crew
01

Meandering stream

Multi-drop stream with pool-and-riffle grading — sounds like moving water, not a hose.

Included in every build
02

Bog / wetland filter

Planted bog filter polishes water biologically — clear pond, less mechanical filtration.

Included in every build
03

Native aquatic plants

Water lilies, iris, pickerel, and marginals matched to your exposure and hardiness zone.

Included in every build
04

Boulder character

Real boulder placement — not veneered stone — for a natural, aged look.

Included in every build

Frequently Asked

Answers before
you call.

01

What's the difference between a koi pond and an ecosystem pond?

Koi ponds are fish-first: deep, heavily filtered, minimal plants. Ecosystem ponds are plant-first: shallower zones, bog filtration, mixed fish and native plants.

02

Can I run a stream without a full pond?

Yes — stream-only builds discharge to a hidden basin (pondless), giving you the sound and motion without the open water.
