Most garden projects go wrong for the same reason. People start with the fun part — picking paving slabs, choosing plants — and only think about levels, drainage and access once the digger is already booked.
Get the order right, and the rest becomes straightforward. This guide walks through the whole garden landscaping process the way a landscaper actually works: survey first, drainage second, hard landscaping third, planting last. It covers UK planning rules, realistic 2026 costs, what changes on clay soil, and the mistakes that cost people money twice.
How to Landscape a Garden in 10 Steps (Quick Summary)
- Decide how you’ll use the space before you design anything.
- Measure the garden and check the levels, not just the outline.
- Test your soil and note where the sun falls through the day.
- Check planning rules — especially for front gardens, raised decking and fences.
- Plan where water will go before you plan where paving will sit.
- Set a budget and split it between hard landscaping and planting.
- Clear the site, dig out, and set your levels and falls.
- Build the hard landscaping: patio, paths, walls, steps, fences.
- Prepare the soil properly, then turf and plant.
- Add lighting, irrigation and finishing touches last.
Each step below explains the reasoning, the numbers, and what goes wrong when people skip it.
The Full Garden Landscaping Process, Step by Step
Step 1: Work Out How You’ll Actually Use the Garden
A garden design that ignores daily habits looks good in a drawing and annoys you for a decade.
Sit down and answer these before sketching anything:
- Where does the sun hit at 6 pm in June? That’s where the seating goes, not wherever’s closest to the back door.
- Do you need a bin store, bike store, or somewhere to dry washing? These get forgotten and then bolted on badly.
- Are there children or a dog? That changes lawn size, planting choice and whether gravel is a good idea.
- How much maintenance will you genuinely do? Be honest. A border that needs weekly attention becomes a weed bed by August.
- Will you eat outside? A table for six needs about 3m x 3m of clear paving, more if chairs need to push back.
Write down the three things you want most. Everything else is negotiable when the budget tightens — and it usually does.
Step 2: Survey the Garden Properly
Measure the boundaries, then measure the levels. Level changes are what turn a £6,000 job into a £16,000 one, and they’re invisible on a plan view.
What to record:
| What to check | Why it matters |
|---|
| Garden dimensions and boundary lines | Sets the design and the fencing cost |
| Level differences from house to rear boundary | Determines retaining walls, steps, and how much soil moves |
| Damp proof course (DPC) height on the house wall | Finished paving must sit at least 150mm below it |
| Position of manholes, gullies, drain runs | These must stay accessible; you cannot build over them |
| Side access width and gate height | Under about 900 mm, and everything comes through the house by barrow |
| Existing trees and their spread | Roots, shade, and possible legal protection |
| Where water pools after heavy rain | Shows you the low points and drainage problems |
The DPC point catches people out constantly. Paving laid too high against the house bridges the damp proof course and pushes moisture into the wall. Two brick courses of clearance is the working rule. If you’re paving right up to a threshold, you need a drainage channel there instead.
Checking levels without kit: run a taut string line from a peg at the house wall to a peg at the far end, keep it level with a spirit level, and measure down to the ground every couple of metres. Crude, but it tells you whether you have a 200mm drop or a 900mm one — and that’s the number that shapes the budget.
Step 3: Know Your Soil and Light
Soil determines what survives. Light determines what thrives.
A two-minute soil test: dig a hole about 30cm deep. Squeeze a handful of damp soil.
- Rolls into a smooth sausage and stays shiny — clay.
- Feels gritty and won’t hold shape — sandy.
- Holds shape but crumbles when poked — loam. That’s the good one.
- Pale, stony, fizzes with vinegar — chalky and alkaline.
Then fill the hole with water and watch it. Gone within an hour or two: free-draining. Still sitting there the next morning: you have a drainage problem to solve before anything else happens.
Much of North London, including large parts of Enfield, sits on London Clay, with river terrace gravels along the Lea Valley to the east. You can check the bedrock under any address free on the British Geological Survey map viewer. Clay holds water in winter, sets like concrete in summer, and swells and shrinks with the seasons.
Light: track shade across a full day and note it. North-facing gardens get sun at the far end; south-facing get it near the house. Shade under a mature tree is dry shade, which is a much harder planting brief than damp shade and needs entirely different plants.
Step 4: Check the Planning Rules Before You Commit
Most back garden work is permitted development. Front gardens and anything raised are where people get caught.
Front gardens and driveways
Since October 2008, paving your front garden has had its own rule. If the area is more than five square metres and you use an impermeable surface that drains onto the road, you need planning permission. Use a permeable surface, or direct the run-off into a border, lawn, or soakaway on your property, and no permission is needed regardless of size.
Permeable options include gravel, permeable block paving, porous asphalt and resin-bound surfacing. Standard concrete, sealed imprinted concrete and normal tarmac are impermeable unless the run-off is handled.
Five square metres is roughly one parking space, so almost any real driveway clears that threshold.
Decking and raised patios
Decking and raised platforms are permitted development only if:
- No part sits more than 300mm (30cm) above ground level at any point.
- The decking, together with outbuildings and other structures, covers no more than 50% of the garden.
- None of it sits forward of the principal elevation of the house.
Go above 300mm anywhere, and you need planning permission. On a sloping garden that’s easy to breach without realising — the deck can be 150mm high at the house and a metre high at the far end. Councils take overlooking seriously, and enforcement notices for raised decking are common.
Fences, walls and gates
Two metres is the general maximum height without permission. That drops to one metre where the boundary adjoins a highway used by vehicles, or a footpath beside one. Height is measured from ground level on the higher side.
Trees
Trees can be protected by a Tree Preservation Order, or simply by sitting in a conservation area. In a conservation area, you generally have to give the council six weeks’ written notice before pruning or felling a tree above 75mm trunk diameter. Unauthorised work on a protected tree is a criminal offence with serious fines. Enfield publishes its protected tree map and notification process on the council’s tree protection page.
The ones nobody mentions
- Conservation areas and Article 4 directions can remove permitted development rights entirely. Check before you spend on a design.
- Flats and maisonettes don’t get householder permitted development rights at all.
- The Party Wall etc. Act 1996 applies if you excavate within 3 metres of a neighbour’s building and go deeper than their foundations. Retaining walls and deep footings can trigger it.
- Retaining walls over about a metre should be designed properly, not built by eye. A failed retaining wall is dangerous and expensive.
Step 5: Solve Drainage Before You Design Anything
Water is the single biggest cause of landscaping failure in the UK, and it’s almost always designed out at the start rather than fixed later.
The rules of thumb:
- Patios need a fall of roughly 1:80 — about 12mm drop per metre — running away from the house.
- Never fall towards a wall, a doorway, or a neighbouring boundary.
- Paved run-off should go to a border, lawn, gully or soakaway, not to the street.
- On clay, a soakaway may not work at all. The ground won’t take the water. You’ll need a linear drainage channel connected to a suitable outlet instead.
Where the water goes matters legally as well as practically. Directing new run-off onto a neighbour’s land creates a genuine dispute, and directing it to the highway is what the front garden rules exist to prevent.
If the garden already floods, deal with the cause first. That might be a French drain across the slope, a raised bed system that takes the water, or breaking up a compacted layer left behind by the housebuilder. Laying a patio over standing water just moves the puddle somewhere less convenient.
Step 6: Set the Budget — And Know Where It Goes
The uncomfortable truth about landscaping costs is that most of the money is spent on things you’ll never see again once the job is finished.
Groundworks — excavation, waste removal, sub-base, drainage — commonly account for 30% to 50% of a hard landscaping budget. That’s before a single slab is laid.
Typical 2026 UK cost ranges
These are indicative ranges reported across UK trade and quote-comparison sites in 2026. They include labour and materials. London and the South East typically run 20% to 30% above these figures.
| Element | Typical range |
|---|
| Full garden landscaping, per m² | £80 – £250 per m² |
| Patio, supplied and laid | £80 – £200 per m² |
| Premium porcelain or natural stone patio | £200 – £300+ per m² |
| Natural turf, including ground prep | £15 – £30 per m² |
| Artificial grass, installed | £60 – £120 per m² |
| Timber fencing | £25 – £60 per linear metre |
| Retaining walls | £150 – £300 per m² of facing |
| Breaking out and removing existing concrete | £40 – £80 per m² |
Whole-project bands most people land in: a refresh with turf, tidied borders and a small patio from around £3,000–£5,000; a mid-range project with new patio, fencing, lawn and planting at roughly £8,000–£18,000; a full redesign with level changes, walls, lighting and drainage from £18,000 upwards.
These are ranges, not quotes. Your garden cost depends on access, level changes, ground conditions, and how much material has to leave the site. Only a site visit produces a real figure.
The costs people forget
- Muck-away. Excavated soil and broken concrete have to go somewhere. Skips and grab lorries add up fast, and clay is heavy.
- Access. No side gate means every barrow of aggregate goes through the house or over the neighbour’s land. Some jobs price 20–30% higher on access alone.
- Making good. Reinstating the lawn after machinery has crossed it, repointing where the patio meets the house, painting new fence posts.
- VAT. Check whether quotes include it. A 20% surprise ruins a budget.
How to split the money
A useful starting split is roughly 70% hard landscaping, 30% soft — paving, walls, decking and fencing take the larger share, with turf, soil and plants taking the rest. If you need to cut costs, shifting that balance toward planting is the biggest single lever you have. Grass and shrubs cost a fraction of what paving costs per square metre.
A better saving than cheper materials: reduce the paved area rather than downgrade the paving. A smaller patio in decent stone beats a sprawling one in slabs that spall after three winters.

Step 7: Get the Order of Works Right
Sequence isn’t a formality. Doing things out of order means doing them twice.
- Clear the site. Remove old structures, unwanted planting, rubbish. Protect anything staying.
- Set out. Mark the design on the ground with pegs, string and marker paint. Live with it for a few days. Shapes read differently at full size.
- Excavate and set levels. Establish the finished levels and falls now — everything else references them.
- Install drainage and ducting. Any pipe, channel, cable or irrigation line that runs under a hard surface goes in now. Retrofitting means digging it all up.
- Build retaining structures and foundations. Walls, steps, footings for anything structural.
- Lay sub-bases. Compacted in layers, not all at once.
- Lay paving, build steps, install decking.
- Install fencing and boundaries. After paving, so you’re not working around new posts, but before topsoil goes down.
- Prepare soil and shape beds.
- Turf and plant.
- Lighting, furniture, pots, mulch.
Fencing sits at step 8 deliberately. Post holes on a boundary need access along that boundary, and dug spoil is easier to handle before the lawn exists.
Step 8: Groundworks — The Part That Decides Whether It Lasts
Excavation depth. A pedestrian patio is typically dug out 150–250mm to allow for sub-base, bedding and the paving itself. Driveways go deeper. On soft or clay ground, dig deeper.
Sub-base. Compacted MOT Type 1 crushed aggregate, laid and whacked down in layers of 50–75mm rather than in one thick pass. A single deep layer looks compacted on top and stays loose underneath. That’s where the settlement comes from two winters later.
Bedding. Paving should go onto a full mortar bed, not five dabs of mortar under each corner. The “five spot” method leaves voids, and voids fill with water, and water freezes. It’s the most common cause of cracked slabs in the UK.
Clay ground specifically. Clay moves. It swells when wet and shrinks when dry, and in a dry summer that movement is enough to open joints and tilt slabs. On clay you want a deeper, well-compacted sub-base, a geotextile membrane between subsoil and aggregate to stop the two mixing, and drainage that doesn’t rely on water soaking away into ground that won’t accept it. Fence posts want concreting properly and set below the seasonal movement zone.
Membranes. A woven geotextile under the sub-base separates layers and stops fines migrating upward. Plastic sheeting under a lawn is a different thing entirely — it traps water and kills the grass. Don’t confuse the two.
Step 9: Hard Landscaping Choices
Paving materials compared
| Material | Strengths | Watch out for |
|---|
| Porcelain | Very low porosity, colour-stable, easy to clean, doesn’t stain | Slippery if you choose an unsuitable finish; needs a slurry primer on the back of each slab; harder to cut |
| Indian sandstone | Warm natural look, wide availability, forgiving to lay | Porous — takes algae in shade; colour variation between packs |
| Concrete slabs | Cheapest per m², consistent sizing | Fades and can spall in frost; obviously manufactured |
| Block paving | Individual blocks can be lifted and relaid; permeable versions available | Needs proper edge restraint or it spreads; joints need sand topping up |
| Gravel | Cheap, permeable, good for drainage and security | Migrates without edging; hard for wheelchairs, buggies and heels |
| Resin-bound | Smooth, permeable, no joints | Needs a sound base beneath; specialist installation |
For shaded North London gardens, porcelain earns its extra cost. Sandstone in permanent shade grows algae and needs cleaning every year or two; porcelain doesn’t absorb enough water for that to happen.
Decking
Composite decking costs more upfront and needs almost nothing afterwards. Softwood costs less and needs treating, and it will need boards replacing eventually. Both need airflow underneath — a deck built tight to the ground rots from below.
Keep it under 300mm to stay within permitted development, and put a non-slip finish anywhere it gets shade or rain, because wet timber decking in a shady garden is genuinely dangerous.
Fencing
Concrete posts and gravel boards outlast timber posts substantially, because the rot happens at ground level where the post meets wet soil. Closeboard fencing lasts longer than lap panels. Check who owns the boundary before you take anything down — the deeds say, and neighbours often assume wrongly.
Solid fencing in a windy spot acts as a sail. Slatted or hit-and-miss designs let wind through and stay standing.
Step 10: Soft Landscaping — Soil, Turf and Planting
Soil preparation
This is where most DIY gardens fail. Machinery and foot traffic compact the ground during the build. Laying turf or plants straight onto compacted subsoil gives you shallow roots, standing water and a lawn that dies in its first dry summer.
Before anything goes in:
- Break up the compacted layer to a spade’s depth.
- Remove builders’ rubble, not just the visible pieces.
- Add organic matter — well-rotted compost or manure — and work it in. On clay this improves structure; on sand it improves water retention.
- Aim for 100–150mm of decent topsoil for lawn, 300mm+ for beds and considerably more for anything you want to grow well.
Turf
Lay turf onto a firm, raked, level bed. Butt the joints tightly and stagger them like brickwork. Water it thoroughly and keep watering daily for the first two to three weeks — new turf dies from drying out at the seams more often than from anything else. Stay off it for two or three weeks.
Best time: autumn, roughly September to November, when the soil is still warm and rain does the watering for you. Spring works. Mid-summer turfing is a watering commitment most people won’t keep.
Seed is far cheaper than turf but takes a full season to look established, and it needs bare soil kept moist and bird-protected. Fine if you can wait.
Artificial grass
Worth being clear-eyed about. It’s genuinely low maintenance, it stays green in drought, and it works in permanently shaded gardens where real grass gives up. It also gets uncomfortably hot in direct summer sun, supports no wildlife, needs a proper sub-base like paving does, and has a finite life before it needs replacing and disposing of. It’s not maintenance-free either — it needs brushing and rinsing, and it collects leaves.
Planting
Structure first, then filler. Trees and larger shrubs set the bones of the garden; perennials fill the gaps. A common ratio is roughly one third evergreen so the garden isn’t bare from November to March.
Practical points:
- Check the mature size on the label, not the pot size in the shop.
- Plant in odd-numbered groups of three or five. It reads more naturally than pairs.
- Bare-root plants and hedging go in between November and March and cost a fraction of potted equivalents.
- Keep trees away from the house. On shrink-swell clay, thirsty species close to shallow foundations are a subsidence risk — willow, poplar and oak are the usual suspects.
- Mulch beds with 50–75mm of bark or compost. It suppresses weeds, holds moisture and slowly feeds the soil.
Step 11: Garden Lighting and Finishing Touches
Run electrical ducting during groundworks even if lighting comes later. An empty duct costs almost nothing; digging up a finished patio costs a great deal.
Outdoor mains wiring is notifiable work under Part P of the Building Regulations and should be done by a qualified electrician. Low-voltage systems are simpler and safe for DIY.
Light what’s worth seeing — a specimen tree, a wall texture, the steps — rather than flooding the whole garden. Warm-white, downward-facing fittings on the lowest usable output. Bright lights aimed sideways go straight into a neighbour’s window.
Best Time of Year to Landscape a Garden
Enfield’s weather shapes when each job is best done, and the table below sets out what suits each season.
| Season | Good for | Avoid |
|---|
| Spring (Mar–May) | Planting, turfing, starting builds | Contractors are busiest; lead times stretch |
| Summer (Jun–Aug) | Hard landscaping, dry ground for machinery | Turfing and planting unless you’ll water daily |
| Autumn (Sep–Nov) | Turfing, planting, hedging — the best window | Late autumn concrete work if frost threatens |
| Winter (Dec–Feb) | Design, quotes, bare-root planting, clearance | Mortar work in frost; heavy machinery on saturated ground |
Booking a project in winter for spring delivery usually gets you better availability and more of the contractor’s attention than calling in April.
Common Garden Landscaping Mistakes and What They Cost
Paving laid too high against the house. Bridges the damp-proof course and causes damp inside. Fix: lift and relay, or install a drainage channel. Expensive either way.
No fall, or fall towards the house. Water pools on the patio and runs at the wall. Fix: relay the whole thing.
Thin or badly compacted sub-base. Slabs rock and sink within two winters. Fix: take up and start again.
Five-spot mortar bedding. Voids under slabs, cracks after frost.
Turf onto compacted ground. Yellow patches, standing water, and a lawn that dies in the first hot spell.
Impermeable front garden paving without permission. Councils can and do issue enforcement notices requiring removal.
Raised decking above 300mm without permission. Same outcome, plus an unhappy neighbour.
Planting for how it looks in the pot. Three years later, everything’s fighting for space and the shrub by the path has swallowed the path.
Ignoring access. Discovering on day one that the side gate is 700mm wide changes the price and the programme.
Landscaping Ideas for Different Garden Types
Small gardens
Diagonal layouts make a small plot feel larger than square ones do. Don’t wall the perimeter with narrow beds — a couple of generous beds beat a thin strip all the way round. Multi-use furniture, vertical planting on fences, and a single larger tree rather than several small ones all help. Resist paving the whole thing; a small green area does more for the feel of the space than another two metres of patio.
Sloping gardens
Two approaches: terrace it into level platforms with retaining walls, or work with the slope using stepped planting and a winding path. Terracing costs considerably more — retaining walls, drainage behind them, steps, handrails — but gives you usable flat space. Remember the 300mm decking rule and check whether new raised areas overlook neighbours, because that’s what planning objections are made of.
Water always runs downhill. Whatever you build, plan where it collects at the bottom.
Shaded gardens
Reflected light helps: pale paving, light fence colours, mirrors used carefully. Plant for the conditions rather than fighting them — ferns, hostas, hellebores, epimedium, box, hydrangea. Porcelain paving over sandstone, because shade means algae. If a neighbour’s tree causes the shade, you can prune growth overhanging your boundary back to the line, but only if the tree isn’t protected, and the cuttings legally belong to the tree’s owner.
Clay soil gardens
Never dig or walk on clay when it’s wet — you’ll compact it into something nothing will grow in. Add organic matter every year rather than trying to fix it in one go. Raised beds sidestep the problem entirely for planting. For hard landscaping, expect deeper excavation, more sub-base, and a drainage solution that doesn’t assume water will soak away.
Front gardens
Keep some of it planted. Beyond the planning rules, a fully paved front garden makes the house look harder and does nothing for the street. A permeable driveway with planted margins costs no more than a fully paved one and both drains better and looks better.
Should you do it yourself or hire a landscaper?
Reasonable DIY: planting, turfing a flat area, painting fences, gravel paths with edging, small raised beds, mulching, low-voltage lighting.
Worth paying for: anything involving level changes, retaining walls, drainage, patios over about 15m², driveways, structural work near boundaries, and any job needing a mini-digger.
If your project appears anywhere on that second list, get it priced by a professional landscaper in Enfield before you order materials. A quote costs nothing and usually saves more than it reveals.
The honest reason isn’t skill — it’s that the failure mode is expensive. A badly planted shrub costs £15 to replace. A badly laid 30m² patio costs several thousand to take up and do again, and you’ll have lived with it settling for two years before you accept it needs redoing.
Access is the other factor. Professionals have grab lorries, whackers, and the ability to move eight tonnes of aggregate in a day. Barrowing that through a house takes a fortnight and ruins the hallway.
Landscaping a garden in Enfield and North London
A few things apply specifically to gardens in this part of London.
Ground conditions. Much of the borough sits on London Clay, with river terrace gravels toward the Lea Valley in the east. Clay affects everything: sub-base depth, drainage design, fence post fixing, and which trees you can safely plant near the house. It’s the main reason a patio that would be straightforward in Norfolk needs more groundwork here.
Surface water. North London’s drainage network is under pressure, and paved-over front gardens are a recognised contributor to surface water flooding. The permeable paving rules exist for that reason, and local authorities take them seriously.
Conservation areas and protected trees. Enfield has a number of conservation areas and around the borough there are trees under Tree Preservation Orders. Both can restrict what you build and what you cut back. Check the council’s planning constraints information before finalising a design that involves removing a tree or building near one.
Housing stock. A lot of Enfield’s suburban housing dates from the interwar period — long, narrow rear gardens, side access of variable width, and original shallow foundations that make tree planting near the house worth thinking about carefully.
Access. Terraced and semi-detached streets across Enfield, Edmonton, Palmers Green and Winchmore Hill often have restricted parking and narrow side returns. That affects how materials reach the garden and therefore what the work costs.
Conclusion
The gardens that still look good in ten years share the same things: levels sorted properly, water going where it should, a base built deeper than it needed to be, and planting chosen for the conditions rather than the photograph.
If your project involves changes in level, drainage problems, clay ground or anything structural, get a landscaper out to look at it before you commit to a design. A site visit costs nothing and usually changes at least one thing about the plan.

FAQs
How long does it take to landscape a garden?
A small refresh takes two to four days. A mid-sized project with a patio, fencing and turf usually runs one to three weeks. Full redesigns with level changes, walls and drainage take four to eight weeks or longer. Weather delays are normal on groundwork and mortar work.
What’s the cheapest way to landscape a garden?
Keep the existing levels, use gravel rather than paving, grow from seed instead of turf, plant bare-root in winter, and buy smaller plants and let them grow. Changing levels is where costs escalate, so working with what you have saves the most.
Should I lay turf or artificial grass?
Real turf if the area gets reasonable light and you’ll mow it. Artificial if the garden is deeply shaded, gets heavy dog or child traffic that kills grass, or if mowing genuinely won’t happen. Artificial costs more to install and has a replacement cost at end of life, so the long-term saving is smaller than it first appears.
Can I lay a patio on soil?
No. Paving laid on soil sinks, tilts and cracks. It needs excavation, a compacted sub-base and a proper bedding layer. Skipping the base is the most expensive shortcut in landscaping.
What order should I do my garden in?
Clear, set out, excavate, drainage and ducting, foundations and walls, sub-base, paving and decking, fencing, soil preparation, turf and planting, lighting last.
