Rickmansworth Aquadrome
Old gravel pits flooded into lakes, now ringed with woodland. A good place to see which trees and marginal plants settle naturally on Rickmansworth's wet ground.
Learn more about Rickmansworth AquadromeGarden landscaping in Rickmansworth starts with a question most towns never have to ask: where does the water go in February? On the valley plots near the Colne, the Chess and the canal, the ground can be soaking a spade's depth down after a wet month, and that changes how high a terrace sits, how a wall is founded and what the paving is laid on. Up in Moor Park the ground is kinder but the estate covenants are stricter. We survey for both, then draw the garden.
A few details about the garden is all we need - we will be in touch to arrange a time to come and see it. No charge for the visit and no hard sell afterwards.
The Business Behind It
Every employee vetted.
Drainage and levels on Rickmansworth's river gravels need careful hands. The people Mark sends have all been vetted through his hiring process, which involves test projects and, often, further training and courses with suppliers.
Mark holds them to a high fitting standard and organises every day of a build the night before. Albert covers the phone and the paperwork, leaving Mark free to stay on top of the job.
Rickmansworth
Sinking a seating area into the lawn feels cosy on paper. On Batchworth gravels it fills like a bath every winter. We lift terraces slightly instead, keep them under the 30cm permission threshold, and step down into the garden rather than up out of a puddle.
A garden wall on saturated gravel needs a wider, deeper foundation than the same wall on chalk up the hill. We size footings from what the test pit shows, so nothing leans after its third winter.
Permeable paving over an open-graded base gives storm water somewhere to go other than toward the back door. It also keeps a Rickmansworth front garden on the right side of the five-square-metre paving rule without an application.
Walls, railings, gates and front hedges on the Moor Park estate answer to the residents' company covenants as well as the council. We design to those terms from the start, so the drawing goes for approval once rather than three times.
The Cedars estate plots are generous and flat, which sounds ideal until you notice the eye runs straight to the back fence. Low walls, a change of surface and a single step can break that length into rooms without losing the sense of space.
Every scheme gets a drainage drawing: falls, channel drains, soakaways sized for gravel that may already be full, and planted low points that can take a flush of water. Nobody should have to guess where a downpour ends up.
Before You Choose
Ask when they would check your water table. If the answer is "we'll see when we dig", the decision about your terrace height is being left to the day the excavator opens the ground in November. A designer who knows Rickmansworth will want a trial hole during the survey, ideally in winter, and will record the level so the drawings can be set from it. A summer survey can miss the problem entirely, because the same hole may be bone dry in August. Fair enough if that's when you call us - we'll simply come back.
Ask what the paving sits on, and why. On wet valley ground a standard bound sub-base can trap water under the slabs, which then lifts and stains them. Permeable construction, or at least deliberate falls to a drain or a border, is usually the better answer. You want someone who can explain the choice for your plot rather than reciting one spec for every job. If they can't say where the water goes once it has passed through the paving, keep asking.
If you live in Moor Park, ask whether they have worked to the estate's covenants before and how the approval process runs. Boundary heights, materials and front-garden layouts are all in scope there. A landscaper who hasn't met those rules will learn them on your project, and possibly after building the wall. That is an expensive way to find out what the covenant says about brick colour, so ask early and ask for an example.
Compared
Most Rickmansworth gardens near the rivers end up in one of these three camps. They behave very differently by the second winter.
| Designed around the water table | Standard patio on wet ground | Leave it as lawn | |
|---|---|---|---|
| Terrace level | Set from a measured winter water reading | Laid flush with the lawn by habit | No terrace, just grass to the door |
| Base construction | Permeable or deliberately drained to a set point | Bound base that holds water under slabs | Nothing built, nothing to fail |
| After heavy rain | Water moves to soakaways and planted low areas | Puddles sit on the paving for days | Lawn squelches and ruts until spring |
| Wall foundations | Sized for saturated gravel from the test pit | Generic footing, risk of tilt over time | Not applicable |
| Usable months | Dry footing to sit out most of the year | Fine in July, slippery and green by January | A summer garden only |
| Moor Park frontages | Drawn to the covenants before approval | Often built first, queried later | No change, so no approval needed |
Our Process
The survey here leans harder on water than anywhere else we work, so the first stage often includes a winter trial hole. From there the drawings follow the same seven steps as every project.
We walk the garden with you and listen more than we talk. Then the measuring starts: levels, orientation, drainage behaviour, existing trees worth keeping, and test pits to find out what soil you genuinely have rather than what the area is assumed to have.
A scaled masterplan showing the whole garden - spaces, routes, levels, structures and planting zones - with mood imagery for materials and atmosphere. This is where you react, argue and change things. Far cheaper to move a terrace on paper than in stone.
The agreed concept is developed into construction drawings and a species-by-species planting plan: setting-out dimensions, wall and step details, levels, lighting positions, and every plant named with its quantity and pot size.
Because the design is fully drawn, the build can be priced properly - each element itemised, so if the figure needs trimming you choose what changes rather than watching quality quietly disappear from everything.
Groundworks, drainage, terracing, walls, steps and structures, built off the drawings by our own landscaping team. Setting-out is checked against the plan, and sub-bases and falls are treated as the point of the job, not the boring bit before the paving.
Beds are decompacted and improved before a single plant goes in - on this area's clay-with-flints and chalk that preparation decides whether a border establishes or sulks. Then the planting plan is set out on the ground, adjusted by eye, and planted.
We walk the finished garden with you, hand over the plans, plant list and care calendar, and come back during the first season - because a designed garden is at its most vulnerable in its first year, not its first week.
Detail
Why do so many Rickmansworth patios go green and slippery? Usually because they sit at, or slightly below, the lawn on ground that holds water through the winter. Our fix is simple to describe and fiddly to build. Terraces go a little higher than the surrounding garden, edges are detailed so water runs off rather than across, and lawns are re-graded so the lowest point of the garden is somewhere we chose, not wherever the gravel decided. Often that low point becomes a planted swale or a damp bed that earns its place.
That planted low ground is where the hard landscaping hands over to the borders. The plants that will sit happily in a wet February and a dry July are a specialist choice on this soil, and we cover them in more depth on our planting design page for Rickmansworth gardens. On a Metroland plot the two go hand in hand: the walls and steps give the garden its rooms, and the planting gives each room a reason to walk into it.
Reassurance
Budget
£25,000 – £90,000
Rickmansworth projects tend to split by ground. Valley gardens put more of the budget below the surface, into drainage and deeper bases, while Moor Park projects spend more on boundary work and the time it takes to get approval. The design fee is the same either way, and both ends of the range turn up here.
Plots in Batchworth and near the Aquadrome often need channel drains, larger soakaways or a re-graded lawn before anything decorative is priced. On wet ground that groundwork is a real share of the build.
On the Moor Park estate, front walls, railings and gates are built to the covenant's terms and materials. That can mean better brick, hand-made railings and an approval stage in the programme.
A wide garden on the Cedars Estate or around Nightingale Road simply has more square metres to build. Giving it structure means more walling, steps and paths than a narrow terrace garden would need.
The Area
The town's best-known outdoor spaces are all about water, which is fitting given what we spend our surveys measuring. Each is worth a visit with a garden in mind.
Old gravel pits flooded into lakes, now ringed with woodland. A good place to see which trees and marginal plants settle naturally on Rickmansworth's wet ground.

Feedback

“We had lived with a sloping, unusable lawn in Batchwood for eleven years and assumed it was just what the garden was. The masterplan split it into three levels with a long bench built into the top retaining wall, and we now eat outside from April to October. The bit that impressed me most was the drainage they insisted on putting behind the walls - invisible, and clearly the reason nothing has moved.”

“The house was rebuilt two years ago and the garden never caught up - a builder's lawn and a patio that faced the wrong way. They redesigned the whole plot around the new kitchen's sightlines and put in planting with real maturity. Neighbours assume the garden came with the rebuild, which I think is the point.”

“What we wanted was borders like the ones you see at proper gardens, and what we had was clay you could throw pots with. The planting plan came with every species named and a paragraph on why it would cope with our soil. Two summers in, the border is better than the photographs they showed us at concept stage.”

“An outdoor kitchen was my husband's idea and I was sceptical it would ever be used. Because the gas, power and lighting all went in before the paving, it looks built-in rather than bolted on, and we cooked outside more or less every weekend last summer. The festoon lighting on the pergola was their suggestion and it makes the whole thing at night.”

“A proper process from start to finish. Survey with test pits, a concept we pushed back on twice without any sulking, then a build crew who turned up when they said and swept the drive every evening. The care calendar they left us is pinned inside the shed door and actually gets used.”
