There is a particular kind of site visit that stays with you. Not the ones where work is beginning, but the ones where work is being undone.
A terrace that had been laid without accounting for the fall away from the house — water sitting at the threshold every time it rained, slowly working its way under the door. Two years of use, then three weeks of demolition, then the same cost again to get it right. A retaining wall built before levels were properly resolved, so that when the planting scheme was drawn up six months later, the proportions of the whole upper garden were wrong. Not catastrophically. Just permanently. The kind of thing that nags at a site for twenty years.
It is the most common story in residential garden design. The sequence was wrong. The design stage was compressed or skipped. Decisions were made at contractor speed, which is not the speed at which design problems get solved.
The conversation about design fees tends to start in the wrong place. Clients ask what design costs as though it is a line item to be weighed against the build. It is not. The design stage is not an addition to the project. It is the part of the project during which the expensive decisions get made cheaply.
Getting levels right on paper costs nothing relative to getting them right in stone. Resolving drainage in plan means a drain trench and a bit of pipe. Resolving it after the terrace is laid means breaking up what has just been built. Working out the spatial sequence of a garden in drawings — where the path turns, how the eye is drawn through, where the boundary planting sits relative to the sight lines from the main rooms — takes time and expertise, but it costs the same whether the answer is found on the first attempt or the fourth. That same search conducted on site, in materials, costs proportionally more with every iteration.
This is not an argument for expensive design. It is an argument for design that happens before the money is committed to the ground.
The design fee is not where the investment starts. It is where the mistakes stop.
The garden is often the one major investment in a home where normal financial discipline breaks down — not through recklessness, but through a genuine misunderstanding of what the design stage is protecting against. Clients who would never commission structural work without a survey, or specify materials without understanding what they are buying, will compress the design stage because the drawings feel like an overhead rather than a safeguard.
Part of this is the industry’s fault. Too much of garden design is presented as an aesthetic service — as though the drawings are primarily there to show the client what things will look like, rather than to resolve how things will work. That framing makes the design fee feel optional. It is not optional. It is the part of the project where the ground is examined, the site conditions are understood, the sequencing is established, and the expensive decisions are made while they are still cheap.
The clients who have been through a project that went wrong once do not ask whether design is worth paying for. They already know.
A well-designed garden built once costs less than a reasonable garden built twice.
