A pond, a real asset for your garden.

A pond is more than a water feature, it is a living world for dragonflies, birds and stillness. Roy Kwinten builds natural ponds, koi ponds and swim ponds across the Kempen region.

Types of pond

Which pond fits your garden?

Every garden is unique. We listen, then create a pond that is beautiful, durable and low-maintenance.

Natural pond

A natural pond does not need a technical filter. It self-filters through a thoughtful planting zone (helophyte filter). Result: clear water, dragonflies, frogs, settled fish. Perfect for landscape gardens.

Koi pond

For koi you need more technique: bottom drain, biofilter, aeration and sufficient depth (minimum 1.5 m). We build koi ponds where fish flourish for years, with a balance of technique and aesthetics.

Swim pond

A swim pond combines recreation with nature. A clear swimming area separated from a planting zone that naturally cleans the water. No chlorine, plenty of summer pleasure.

Decorative water feature

A smaller water element, a wall fountain, mirror basin or corten steel container, can add a whole new dimension, even in small courtyard gardens.

Our approach

From first sketch to living water.

Building a pond is not just about creating an attractive water feature. It is about seamless garden integration and balancing water with greenery.

1. Plan & location

We choose the best spot together: sun hours, view from the house, distance from trees (leaf fall), soil type.

2. Groundwork

With our own equipment we dig the right shape and depth, ensure correct sub-base and drainage.

3. Liner or concrete

Depending on the pond we choose EPDM liner or (for koi) a concrete build. Both have advantages.

4. Filtering & technology

For koi ponds: biofilters, UVC, aeration. For natural ponds: a helophyte filter with the right purifying plants.

5. Planting & finishing

Edge plants, water lilies, floaters, edges in natural stone or wood. The pond becomes part of the garden.

Frequently asked

What clients usually want to know.

How much maintenance does a pond need?

A well-designed natural pond needs minimal maintenance, a few times a year cutting back edge plants, scooping autumn leaves, an annual technical check. Koi ponds need more: cleaning filters, testing water.

Can I keep koi without a big technical installation?

A few goldfish or small koi in a large natural pond can work. For real koi (which grow to 70 cm) a proper filter system is essential.

What does building a pond cost?

Strongly depends on size and type. A small decorative water feature starts from €5,000. A complete koi pond with technique can rise to €30,000+. You get a clear quote after a first conversation.
