Landscape Design · Ponds · Aquariums
Bespoke water environments crafted to transform your space into a living, breathing ecosystem — from koi ponds to coral reefs.
About the Designer
I'm Marcus Valen, a certified landscape designer with a lifelong passion for water. Every project I undertake is guided by the belief that water is not merely a feature — it is the soul of a landscape.
From intimate backyard koi ponds to sprawling estate water gardens, freshwater planted aquariums to thriving saltwater reef systems, I blend ecological science with artistic vision to create environments that sustain themselves and captivate everyone who encounters them.
What I Offer
Every water environment is unique. I offer end-to-end design, build, and maintenance services tailored to your vision and ecosystem.
Custom-shaped naturalistic ponds with waterfalls, streams, and biofilters. Designed to blend seamlessly into your landscape while supporting healthy aquatic life.

Immersive Environments
Whether freshwater or saltwater, every aquarium I design is a self-sustaining world. The balance of biology, chemistry, and aesthetics creates something that is never the same twice.
Precision planting techniques using CO₂ injection, full-spectrum lighting, and carefully selected aquatic plants to create a living green canvas.
Full SPS and LPS coral systems with automated water changes, calcium reactors, and PAR-tuned lighting for explosive coral growth.
Authentic recreations of natural habitats — Amazon rivers, African rift lakes, Asian streams — that let fish express natural behaviors.
IoT-enabled monitoring of pH, temperature, TDS, and nitrate levels with automated dosing and alerts to your phone.
How It Works
We explore your space, discuss your vision, and analyze the environment — sun exposure, existing flora, dimensions, and desired aesthetic.
I deliver a detailed 3D concept design with plant and fish selections, technical specifications, and a transparent cost breakdown.
Hands-on construction using premium materials. I oversee every stage — excavation, liner installation, filtration, planting, and livestock introduction.
Optional maintenance plans ensure your water environment remains vibrant, balanced, and beautiful through every season.
Client Stories
"Marcus transformed our barren backyard into a breathtaking koi sanctuary. The pond feels like it has always been there — a completely natural part of the landscape."
"The reef aquarium installed in our restaurant lobby has become the centrepiece guests talk about. The coral growth after just six months is astounding. Exceptional work."
"From the first consultation, Marcus listened. He designed a Dutch planted tank that perfectly matched our minimalist interior. It's like owning a living painting."
"The Japanese garden pond exceeded every expectation. The waterfall sound alone has reduced my stress levels. Worth every single penny — a true master of his craft."
