When to Use Decking in Garden Design

Not every garden needs decking. But there are situations where it is genuinely the best material for the job.

The decision usually comes down to what the space needs to do and how the material fits within the overall design. We have used decking in a small number of projects where it solved a problem or added something a harder material could not. Two of those projects illustrate the point well.

The Millboard steps connect house level to the main garden. The level change is resolved gradually, which makes the descent feel natural rather than abrupt.

When a level change makes decking the practical choice

The garden at our Barnsley project presented an immediate challenge. There was a significant drop from the back of the house down to the main garden level. That kind of level change needs to be resolved before anything else can be designed around it.

Stone steps were one option, but the transition here was too substantial for a single step or two. The design needed something that could descend gradually, feel comfortable underfoot, and work as part of a wider entertaining space rather than just a functional route between levels.

Millboard decking was specified for the steps and the raised platform at house level. The material handles the transition in a way that feels deliberate. Wide, solid treads give a comfortable descent. The warm oak tone sits well against the grey porcelain paving below and the brick of the house behind.

The Millboard steps connect house level to the main garden. LED strip lighting defines the terrace edge after dark, planned into the design from the start.

The platform at the top also creates a pause point. You step outside and land somewhere before moving down into the garden proper. That moment of transition, from inside to outside and from one level to another, benefits from a material that feels warm and considered underfoot.

“Decking works best when there is a clear reason for it. When that reason exists, it earns its place.”

When the material needs to work with a specific feature

The situation in our Retford project was different. The level change was less dramatic, but there was a specific design challenge around the hot tub.

A hot tub introduces a particular set of requirements. The surround needs to be safe to walk on when wet. It needs to be comfortable barefoot. And it needs to sit within the wider design without looking like an afterthought or a product that has simply been placed in the garden.

Millboard was chosen here for all three reasons. The surface texture gives grip underfoot even when wet, which matters around water. The material is comfortable to walk on barefoot in a way that stone or porcelain is not, particularly in cooler weather. And the warm, natural tone of the boards complements the cedar cladding of the hot tub itself rather than competing with it.

The Millboard surround and steps work with the natural cedar of the hot tub rather than against it. The material choice was led by how the space would actually be used.

The curved retaining wall around the hot tub zone is clad in the same Millboard, which ties the feature into the rest of the space. It reads as a designed area rather than a product sitting on a patio.

What makes Millboard worth considering

Millboard is a composite decking product. It is not timber, which means it does not require the same level of ongoing maintenance — no annual oiling, no risk of splitting or warping over time. The surface is moulded to replicate the grain and texture of real wood, which is why it reads as natural in photographs and in person.

It comes in a range of tones and finishes. In both projects above, the choice of colour was made with the surrounding materials in mind, not in isolation. That is true of most material decisions in garden design — the right choice depends on what it sits alongside as much as anything else.

It is also worth being clear that Millboard is not always the answer. For a simple garden terrace, porcelain or natural stone will often be more appropriate and more cost effective. Decking of any kind requires a well-prepared substructure and adequate drainage beneath it. On a flat site with no particular reason to introduce a timber surface, paving is usually the cleaner choice.

Decking as a design decision, not a default

The point both projects illustrate is that decking works best when there is a clear reason for it. A level change that needs resolving. A feature that benefits from a softer, warmer material nearby. A surface that will be used barefoot regularly.

When those conditions exist, it earns its place. When they do not, there is usually a better option.

Material choices in garden design are always most successful when they follow the brief rather than lead it. The question is never simply which material looks good. It is which material is right for how this particular space will be used.
