The Radlett Centre
A 300-seat venue on Aldenham Avenue. Its tree-lined setting is a reminder how much of Radlett's character comes from mature planting rather than buildings.

Post-rebuild garden landscaping on London Clay - groundwork, terraces and screening done in the right order
Your builders have gone. The house is finished, and the garden is what they left behind: ruts where the crane stood, a skip-shaped yellow patch, and turf rolled over whatever was underneath. Garden landscaping in Radlett is, more often than not, the final phase of a rebuild project. We treat it that way. We survey the ground you have now, design terraces sized to the new architecture, and build them on London Clay properly, so the garden finally matches the house it belongs to.

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
A Tested Team For Radlett Landscaping
Every employee vetted.
London Clay makes landscaping hard physical work, and Mark only puts vetted people on it. Before joining, each one completes test projects as part of an unusual hiring process. Many then go on supplier training and courses.
Fitting standards are something Mark guards closely. He writes up each Radlett job in full and plans every day ahead, and Albert in the office keeps the calls and admin under control.

What You Get From Landscaping Done After The Build
Ground fixed before anything goes on it
We find the compacted zones left by plant, cranes and site cabins, then rip or dig them out. New surfaces and planting go onto ground that can drain and root, not onto a hardpan that holds water.
Rubble out, not buried deeper
Builders' debris under fresh turf is common on rebuild plots. We trial-pit the garden, remove what we find and bring in clean topsoil where it is needed. You pay for that once, not every winter.
Terraces in proportion to the house
A doubled house needs a bigger terrace. We size paving to the new rooms behind it, align it with the new openings and set levels from the new finished floor, so the inside and outside line up.
Sub-bases built for London Clay
Clay moves. It swells in winter and cracks in July. Our terraces sit on deeper, well-compacted sub-bases with geotextile separation and falls that move water off, so the paving stays level year after year.
Privacy back, quickly
Next door's rebuild may have added a storey and new windows. We use pleached trees, semi-mature hedging and well-placed structures to screen the overlooked areas from the first day the garden is finished.
One programme, one team
You have just finished managing a build. We run the garden as a single project with a clear programme, fixed price and one contact, and we liaise with your architect where the house design affects the levels.

Before You Choose
Hiring A Garden Landscaper In Radlett: What To Check
Ask how they will assess the ground. After a rebuild, the soil you see is not the soil you have. A serious landscaper will dig trial pits, test for compaction and look for buried rubble before pricing. If you get a quote from a walk round the lawn, the risk sits with you. The first heavy winter will show where the ground was never fixed.
Ask about sub-bases and falls on clay. You want specific answers: depth of compacted aggregate, whether geotextile is used, which way the terrace falls and where that water ends up. London Clay will not absorb run-off quickly, so a terrace that drains toward the lawn simply moves the puddle. If the answer is vague, so will the paving be in three years.
Ask how the garden relates to the house. You have spent a long time on the architecture. The landscaper should be reading your architect's drawings, matching levels to finished floor heights and choosing materials that work with the new facade. Ask to see drawings, not a brochure of past patios. Then ask who handles the protected trees, because on the private roads there are plenty.

Your Options For A Garden After A Radlett Rebuild
Most rebuild contracts include some form of landscaping, usually done last and done fast. Here is how that compares with a design-and-build approach.
| Designed landscaping after the build | Turf laid by the house builder | Patio added by a general contractor | |
|---|---|---|---|
| Compacted subsoil | Found, ripped or dug out before building | Turfed over and left in place | Ignored beyond the patio footprint |
| Buried rubble | Trial-pitted and removed | Usually under the new lawn | Sometimes used as patio fill |
| Terrace size | Set by the new rooms and openings | Not included | Standard size, standard shape |
| Clay drainage | Water led to a soakaway via channel drains | Lawn waterlogs from the first winter | Water shed onto the lawn |
| Privacy from next door | Screening planned where it is needed | Not considered | A higher fence, if asked |
| Match with the architecture | Levels and materials drawn to the house | Generic finish | Whatever paving is in stock |
Our Process
Our Radlett Landscaping Programme
Your project follows the same seven stages as every garden we build. In Radlett the ground investigation gets more time than usual, because rebuild plots hide most of their problems below the turf.
-
Garden consultation and site survey
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.
-
Concept design
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.
-
Detailed design and planting plan
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.
-
Itemised written costs
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.
-
Landscaping and construction
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.
-
Soil preparation and planting
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.
-
Handover and first-season aftercare
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 Groundwork Comes First On A Rebuild Plot
Heavy plant on clay does lasting damage. Two years of dumpers, cranes and stored materials press the subsoil into a dense layer that water cannot pass and roots will not enter. On the surface it looks fine. Underneath, it behaves like a tank. Fix it first: we break up compacted zones, remove debris, restore the soil profile and only then set out terraces and paths.
Planting needs that same recovered ground, so the two are designed together. If your priority is screening and borders, see our planting design for Radlett's clay gardens, which covers semi-mature stock and decompaction in detail. Otherwise we include the planting in the landscaping scheme and build both in one programme.
Reassurance
Groundwork You Will Not Have To Redo
- The construction underneath it all
- Terraces, walls and steps fail from below, not above - a thin sub-base, no drainage behind a retaining wall, mortar where there should be movement. We build those hidden layers as if they were the visible ones, because in three winters' time they might as well be.
- Plants replaced if establishment fails
- Planting is living stock and a small percentage of losses in year one is horticultural reality. Where a plant we supplied and planted fails despite reasonable care, we replace it - and the aftercare visits exist partly to catch problems while they are still small.
- Built to the drawings, checked against them
- The detailed design is not a sales document, it is the build contract. Setting-out, levels and materials are checked against the drawings as the work proceeds, and you can hold the finished garden up to the plan line by line.
- Still answering the phone afterwards
- A garden is not finished at handover - it establishes over seasons. When a question comes up in year two, you will reach the people who designed and built it, not a voicemail that never calls back.
Budget
Garden Landscaping Costs In Radlett
£25,000 – £90,000
Radlett landscaping projects usually fall within this range. The size of the terrace, the condition of the ground after the build and how much instant screening you want are the three things that move a price. You get a fixed figure once the survey and design are done.
Remediating the rebuild
Decompaction, rubble removal and imported topsoil vary plot by plot. On larger gardens around Loom Lane and The Warren, where site traffic ran for months, this can be a sizeable line in the budget.
Clay sub-bases and drainage
London Clay needs deeper sub-bases than lighter ground, plus drainage that leads somewhere useful. On gravel caps toward Shenley the requirement eases, which is why we test before pricing.
Scale of the terrace
A terrace sized to a doubled house can be several times the area of the one it replaces. Natural stone over that footprint is the largest single materials cost on most Radlett jobs.
The Area
Around Radlett, Away From The Building Site
When the garden is finished, these are three local places worth getting out to. We have added a landscape note to each.
Aldenham Country Park
Reservoir water, open parkland and a rare-breeds farm across 175 acres. It is also a good look at how London Clay country handles winter water when left to itself.

Farm buildings converted into independent shops. Courtyard planting in tubs and borders shows which plants cope with heavy clay and full exposure.

Questions
Radlett Landscaping: Your Questions
- We have just finished rebuilding our Radlett house. When should we start on the garden?
- Start the design while the build is finishing. The survey can happen once the scaffold is down, and drawing takes a few weeks. Build work should wait until heavy site traffic has stopped, or you risk new compaction on finished ground. If you plan it this way, landscaping can begin within weeks of handover rather than a year later.
- Why does the lawn the builder laid keep flooding?
- Almost always because it was laid over compacted clay. London Clay drains slowly at the best of times. After months of plant and stored materials, the subsoil becomes dense enough that water sits on top. Laying new turf does not fix that. We decompact the ground, remove buried debris, install land drains where needed and then re-lawn or replant on soil that can absorb water.
- Do we need planning permission for a new terrace or garden walls?
- A ground-level terrace generally does not. Permission is needed for a raised deck or platform over 30cm, walls or fences over 2m (1m next to a road), outbuildings within 2m of a boundary over 2.5m high, or impermeable front paving over 5m². Along the Watling Street conservation area, give the council six weeks' notice of tree work; a tree under a preservation order needs formal consent. All of this goes to Hertsmere Borough Council. We check your plot and handle applications.
- Next door's rebuild now overlooks our garden. What can be done?
- Quite a lot. Pleached trees give screening at first-floor height without taking up ground space. Semi-mature hedging bought by the metre gives instant height lower down. A pergola or garden room can block a direct line of sight. We map exactly where the overlooking happens from your seating areas, then place screening there rather than along the whole boundary.
- Will the new terrace move on clay?
- Not if it is built correctly. London Clay takes up water and swells in winter, then shrinks back as it dries in summer, so the sub-base must be deep and well compacted, separated from the clay by geotextile and kept away from tree roots that dry the ground out. Falls must take water off the paving into proper drainage. Built this way, terraces stay true.
- Can you work alongside our architect?
- Yes, and we prefer to. We take finished floor levels, door positions and facade materials from the architect's drawings and design the garden around them. Where a drainage or level decision affects the house, we resolve it with the architect before anything is built.
Feedback
What Clients Say
Rated 5 out of 5
“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.”
Rated 5 out of 5
“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.”
Rated 5 out of 5
“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.”
Rated 5 out of 5
“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.”
Rated 5 out of 5
“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.”
