Scope
What this checklist covers
The preparation ground these prompts walk through.
- Deciding what a level area on a slope is actually for
- Choosing between cutting into the slope and building it up
- How much garden a level change is allowed to consume
- Where excavated material goes and what arrives to replace it
- Level decisions that reach a boundary or a neighbouring plot
- Recording a level decision so it survives the design stage
Audience
Who this checklist is for
- Owners of a sloping plot deciding how much of it to relevel
- People weighing a single terrace against a series of smaller ones
- Homeowners settling decisions before a landscape professional is briefed
- Anyone shown two level options who has to choose between them
Timing
When to use it
- Writing down what a level area has to do before it is designed
- Weighing a cut into the slope against ground built up on the low side
- Deciding how much of the plot may be given over to steps and banks
- Recording which existing levels must stay exactly as they are
- Preparing the level questions to put to a qualified professional
Limits
When it is not sufficient
This is general planning preparation. These situations need a qualified professional, and often the relevant authority.
- Deciding how any change of level would be supported or drained
- Judging whether ground on this plot can be cut, filled or loaded
- Setting finished levels anywhere near the base of a building
- Deciding whether altering ground level needs consent or notification

1.Deciding what a level area is really for
Making ground level takes space and effort, so it is worth being precise about what it is for before anyone proposes how to achieve it.
Decide and record what the level area has to hold, whether that is a table and chairs, a trampoline, a garden building or simply somewhere a ladder can stand safely.
An area sized for a chair is a different proposition from one sized for a shed, and the purpose is what a designer works back from.
Write down whether you want one generous level area or several smaller ones at different heights, and which you would choose if only one were possible.
Terracing and a single platform ask quite different things of a slope, and stating a preference stops the first conversation starting blind.
Consider whether the flat area needs to sit near the house, in the sun, or where the view is, and note which of the three you would give up first.
These three rarely coincide on a sloping plot, and the trade-off belongs to the household rather than to whoever draws the layout.
Note whether anything on the level area would be fixed in place, such as a garden building or a raised bed, or whether everything on it could be moved.
Fixed items narrow the options for how ground is formed beneath them and usually bring further questions with them.
Whether ground formed on a slope can carry a building or any other fixed load is a question for a qualified engineer.
Decide whether the level area is for daily use or occasional gatherings, and record how many people you would want it to take without feeling cramped.
Daily use argues for something close to the door, while occasional use can justify a longer walk to a better spot.
Write down whether the level area must be usable in wet weather or only in fine conditions, since that changes what the ground beneath it has to deal with.
A surface used through the whole year sits differently in the discussion from one used only when the ground is already dry.
2.Choosing between cutting in and building up
Every level area on a slope is made by removing ground, adding ground, or both. Owners are rarely asked which they would prefer, yet the answer shapes everything after it.
Decide whether you would rather sit tucked into the slope with ground rising behind you, or perched on ground built up with a drop in front of you.
The two feel completely different to be in, and the preference is a real owner decision rather than a technical one.
Record whether a drop at the edge of a built-up area would worry you with children, visitors or pets about, without deciding what should be done about it.
Edge protection and anything guarding a drop are matters for a qualified professional working to the relevant local requirements.
Note whether you would accept losing daylight or outlook to a bank cut in behind a terrace, particularly where that bank would sit close to a window.
A cut-in terrace puts a face of ground where light used to arrive, and it is far easier to picture now than after the ground has moved.
Consider whether you would prefer the slope reshaped more gently rather than levelled at all, and note where that would still leave you nowhere flat.
Regrading is sometimes an alternative to terracing, and saying you are open to it widens what a professional can propose.
Write down whether an established tree, hedge or shrub sits inside the area you want levelled, and note what you would want kept whatever happens.
Ground cannot usually be cut or raised around established roots without consequences, and what matters most is the owner's call.
Ask a qualified arboricultural professional what a tree can tolerate before ground near it is cut away or built up, and confirm locally what applies.
Decide whether you could live with a level area arriving higher or lower than the existing back door, and note which of those you would find harder.
The relationship between a terrace and the door governs daily use and is one of the earliest things a designer has to fix.
Where a finished surface may sit relative to the base of a building must be established by a qualified professional, never assumed.
3.How much garden the level change may take
Steps, banks and retained lines consume garden. Setting a limit before the design starts is more useful than reacting to it afterwards.
Mark on a rough sketch the line you would not want a terrace or bank to cross, and note what you are protecting on the other side of it.
A line drawn by the owner is far easier for a designer to work with than a general wish that the change stays modest.
Decide whether you would rather have a smaller flat area with a gentle bank, or a larger one with something upright holding the ground back.
Banks take more ground and less discussion, while an upright line takes less ground and brings other professionals into the project.
Write down whether the sloping ground you keep still has a job to do, such as planting, play or simply being looked at from the window.
Slope that keeps a purpose is easier to leave alone, and naming that purpose stops it being treated as leftover space.
Note how much lawn you would accept losing to a flight of steps and its landings before the whole idea stops feeling worthwhile.
Steps and their landings absorb more garden than most owners picture, and the tolerance is worth stating before options are drawn.
Consider whether a level change would divide the garden into parts that feel separate, and decide whether that separation is welcome or unwanted.
Terracing creates rooms in a garden, which some households want and others regret once the far level stops being visited.
Record whether a route for a mower, barrow or bin has to survive the level change, and where on the plot that route would then run.
Upkeep routes are the first thing lost to a neat terrace and the first thing missed once the garden is back in use.
4.Levels you are deciding not to touch
Deciding what stays put is as much of a decision as deciding what moves, and it is the part most often left unsaid.
List the levels that must stay exactly as they are, such as the ground at a doorway, an access cover or the base of an existing outbuilding.
Fixed points are what a designer works between, and a missed one usually surfaces after the ground has already been opened.
Ask a qualified professional what must not be covered, raised or built over on your plot before any level is altered.
Note where a drain cover, gully, access chamber or stopcock sits, and record that each has to stay reachable whatever happens around it.
Covers are routinely paved over during level work, and getting back to them afterwards is far harder than leaving them alone.
Decide whether the entrance path and its steps stay as they are, since a level change in the garden often pushes a change onto the approach as well.
Front and back rarely stay independent on a sloping plot, and a decision taken about one has a habit of arriving at the other.
Note any level that a neighbour or a shared structure depends on, and record that you would not alter it without advice from somebody qualified.
Changes affecting a neighbouring level or a shared structure raise legal as well as technical questions; take suitably qualified advice first.
Write down whether the existing lawn level has to stay for any reason, such as a rotary drier base, a swing frame or a post already set into the ground.
Small fixed items anchor a level quietly, and a household usually remembers them only once the ground around them starts to change.
Record where water currently leaves the garden and note that this is a level you have decided not to change on your own account.
Where surface water goes, and any change to it, is a drainage design matter for a qualified professional and must be confirmed locally.
5.Where the ground goes and what arrives to replace it
Levelling produces material and usually consumes some too. Deciding early what you will accept on the plot avoids a design that cannot be built here.
Decide whether you would accept a mound or a reshaped bank somewhere on the plot rather than material leaving the site, and note where it could go.
Keeping material on site changes the whole character of the work, and whether a new mound is welcome is genuinely a decision for the household.
Note whether the existing topsoil matters to you, and record that you would want it kept separate from whatever comes out beneath it.
Topsoil is easily lost during level work, and once it has gone under a heap of subsoil it is difficult to recover.
Write down what is already stored in the garden that would have to move while ground is reshaped, and where each of those things could go instead.
Sheds, log stores and pots all need somewhere else to be, and nowhere to put them is a genuine constraint on a small plot.
Consider whether you would accept the finished lawn or planting sitting noticeably lower or higher than now, and record which way you would rather it went.
Levelling rarely leaves everything where it started, and stating a direction of travel helps a designer set out a first proposal.
Decide whether you would accept a temporary working route being formed across the garden for machinery, and note what stands on that line now.
A working route has to cross something, and choosing it deliberately beats discovering afterwards where the machines went.
Note whether material would have to travel across a neighbour's land or a shared drive, and record that this conversation happens before a design is fixed.
Any use of land you do not own needs the agreement of its owner; ask a suitably qualified professional what should be recorded in writing.
6.Level decisions that reach the boundary
A level change stops at your boundary only on paper. These are decisions to take with the other side of the line already in mind.
Decide whether you are willing to hold any new level change back from the boundary rather than running it right up to the line.
Room at the edge often separates a straightforward job from one that depends on somebody else agreeing to it.
Record whether raising ground near the boundary would let you see further into a neighbouring garden or window, and decide whether you are content with that.
Overlooking created by a raised surface is a common source of objection and much easier to weigh now than to undo later.
Note whether an existing fence or wall on the line would end up part buried or left standing proud if levels change, and record that as an open question.
Whether a boundary structure can tolerate a change of ground level against it is a matter for a qualified engineer and for its owner.
Write down whether you would accept a design that needs a neighbour to agree to something, or whether you would rather stay wholly within what is yours.
Some households are happy to have that conversation and some are not, and the answer legitimately shapes what gets designed.
Consider whether neighbouring ground sits higher or lower along each stretch of the boundary, and decide which stretches you will simply leave alone.
Relative level usually varies along a single boundary, so deciding stretch by stretch is more realistic than one blanket decision.
Record when you intend to raise level work with adjoining owners, and what you would want to be able to show them at that point.
A sketch in hand makes a very different conversation from a description, and choosing the moment is part of the decision.
7.Writing the level decision down so it survives
Level decisions get quietly reversed as a design develops. A written record is what makes that visible when it happens.
Write your level decisions onto the same sketch you will hand over, rather than leaving them in messages, so one document carries the whole picture.
Decisions spread across separate conversations are the ones that get lost, and a single marked sketch is hard to misread.
Record which of your level decisions are firm and which you would trade if the ground turns out to be more awkward than anyone expected.
Marking the flexible ones in advance saves a rushed judgement being made while machinery stands idle in the garden.
Note the date beside each decision and add to the record rather than overwriting it, so the reason a level moved is still traceable afterwards.
Level changes accumulate quietly during design, and a dated trail is the only way to see how the finished ground ended up where it did.
Decide who in the household may agree a change of level once work is under way, and write that down before anybody is on site.
Level questions are often asked on the spot, and knowing who answers prevents two different answers being given to two different people.
List the level questions you are deliberately not answering and are handing to a qualified professional instead.
Naming what you are not deciding is as useful to a professional as naming what you have settled.
Support, drainage and the behaviour of ground behind any change of level are matters for qualified professionals, whatever the layout decision turns out to be.
Keep the sketch, photographs and decision notes together where a future owner or adviser could find them, since garden level questions resurface long afterwards.
Level history is asked about at sale and is almost impossible to reconstruct from memory once the ground looks settled again.
Preparation
Documents and information to gather
Having these to hand usually makes the first conversation shorter and more useful.
- A sketch of the plot marked with the level areas you want and the line they may not cross
- Photographs taken from the window you look at the garden through most often
- Notes on what each level area would have to hold and who would use it
- Any earlier drawing or sale plan showing the garden as it was before your time
- A list of the fixed points you have decided must not move at all
- Your record of anything already reshaped, filled or built up during your time here
Records
Decisions to record before work begins
Write these down in your own words, with the date, so everyone is working from the same version.
- Whether one generous level area or several smaller ones is the priority
- Whether ground would preferably be cut into the slope or built up on the low side
- The limit on how much garden may be given over to steps, landings and banks
- Whether excavated material may stay on the plot or has to leave it
- Which existing levels are not to be altered under any circumstances
- Whether a design that depends on a neighbour agreeing is acceptable to you
Professional review
Questions to discuss with qualified professionals
Bring these to the relevant qualified professional, supplier or authority. Requirements vary by project and location.
- What would this ground allow, given the way you can see it falling here?
- Would cutting into the slope or building up suit this particular plot better?
- What would have to be established about the ground before any level is fixed?
- What would support a level area formed at this point on the slope?
- How would water be dealt with once the ground stops falling the way it does now?
- What has to be confirmed locally before ground levels here are altered at all?
- What access would the work need, and where would excavated material stand?
- Which of my level decisions would you push back on, and what would you suggest instead?
Blind spots
Commonly overlooked items
- The mower route between the new levels, decided last or not at all
- Topsoil buried under the subsoil that came out from underneath it
- A drain cover neatly paved over while the levelling was under way
- How much garden a flight of steps and its landing quietly absorbs
- The rotary drier or swing frame anchored into a level nobody meant to move
- Ground built up against a boundary fence that was never asked to hold it
What this checklist does not do
- Nothing here decides whether ground on your plot can be cut, filled, loaded or left unsupported.
- How a level change is held up, and how water gets away from it, are design matters for qualified professionals in every case.
- Whether altering ground levels needs consent, notification or the agreement of anybody else is to be confirmed locally before work is planned.
- A layout decision recorded here is the starting point for a professional conversation and never a substitute for one.
