Checklist: Planning a New Garden Path Before You Dig

A good garden path looks effortless. It takes you where you actually want to go, stays firm underfoot in February, and never asks you to think about it again. Reaching that point is mostly planning. The digging itself is a weekend's work with a spade and a wheelbarrow; the decisions that make or break the path all happen before the first turf comes up. Work through the checks below, and you will spend your money once.

Start With How the Path Will Be Used

Before anything else, walk the route you have in mind and ask what it has to carry. A route from the back door to the shed that only ever sees footsteps has very different requirements from one that takes a wheelbarrow, a mower or a wheelie bin twice a week.

• Main route: used daily, in all weathers, by everyone in the house. Build this properly, with a solid base and a surface that drains.
• Secondary route: to a compost heap, a side gate, a greenhouse. Can be narrower and looser in construction.
• Decorative or informal path: stepping stones through planting, gravel through a border. Cheaper, but it still needs to be level and stable where feet land.

Then think about width. Around 600mm is the minimum for walking in single file. 900mm feels comfortable and lets two people pass with a bit of shuffling. If the path is the main way into the garden, or anyone in the household uses a wheelchair, walker or pushchair, go for 1.2m and keep the surface firm. On a sloping site, a fall of 1:20 or gentler can be left as a ramp; anything steeper wants steps, with a flat landing at the top and bottom.

Measure and Record Everything

Set out the route with pegs and string, then write down the numbers rather than trusting your eye. Note the total length, the width at each end, and the tightest point along the route — gates, downpipes and shrubs are usually where the space disappears.

Levels matter just as much. Use a long spirit level or a line level on a taut string to work out the fall along the path and across it. Aim for a cross-fall of roughly 1:60 to 1:40, which is about 15–25mm per metre, so water runs off rather than sitting. Where the path meets the house, keep the finished surface at least two brick courses (around 150mm) below the damp-proof course, sloping away from the wall.

Sketch the plan on graph paper with the dimensions written on it. Mark every manhole cover, gully, drain, outside tap, tree root and existing cable or pipe run you can see. That sketch becomes your shopping list, your instructions to yourself and your record if anything needs revisiting in three years' time.

Decide Where the Water Goes

Water is what ruins paths. It lifts slabs, ruts gravel and turns a sub-base into porridge. So before choosing a material, answer a simple question: in a heavy downpour, where does water land on this route, and where should it end up?

You have a few sensible options. A permeable surface — gravel, resin-bound, permeable block paving, or paving with wide open joints — lets water pass through to the ground below, provided the sub-base is also permeable. A channel drain or French drain can take water to a border, soakaway or existing gully. On clay soil, which drains slowly, plan for more generous falls and a proper outlet rather than assuming water will disappear. On a sloping site, think about cut and fill: you may need a shallow retaining edge on the low side to stop the surface creeping.

Check Permissions, Boundaries and Buried Services

This is the section most people skip, and it is the one that can stop a project dead. Check who owns the land you intend to dig, particularly if the path crosses a shared access or a boundary that is not clearly defined. Look at your deeds or lease for covenants restricting hard surfaces, and check whether any nearby tree carries a Tree Preservation Order — roots extend well beyond the canopy, and protected trees can limit what you may dig.

In England, hard surfacing a front garden of more than five square metres may need planning permission unless the surface is permeable or water drains to a soakaway or planted area. Rules differ across the UK, so if your path is at the front of the property, ring your local planning authority and ask. It takes one phone call.

Buried services deserve the same care. Gas, electricity, water, telecoms and drainage can all run under a garden, often shallower than expected. Use a cable and pipe detector, request utility plans through the free national enquiry services, and never assume a pipe or cable is disused. If you are unsure, stop and take professional advice. The same applies to legal questions about boundaries or covenants — a short conversation with the planning department or a solicitor is far cheaper than undoing work.

Match Materials to the Job

Once you know the route, the levels and the drainage, materials become easier to choose. Mortared paving is solid and long-lasting but needs a proper sub-base and a way for water to escape. Dry-laid paving sits on compacted grit or sand, is quicker to lay and easier to lift if you need to get at a drain. Gravel is inexpensive and forgiving, but it migrates without a firm edge, ruts under wheelbarrows and is noisy. Resin-bound surfaces are smooth and permeable but want a stable base. Bark chip is fine for a temporary route through a border, though it will need topping up.

Whatever you pick, consider grip when wet, colour against the house, and how it will look after five winters. Order about ten per cent more than your measurements suggest to allow for cuts, breakages and future repairs — matching a batch two years later is rarely straightforward.

Budget, Tools and Practicalities

Write your budget as a list of lines rather than one hopeful figure: materials, delivery, sub-base and edging, sand or cement, weed membrane, skip or waste removal, tool hire, and a contingency for the unexpected. If you are paying someone to help, add labour.

On tools, borrow or hire what you will only use once. A basic kit for a paving path looks like this:

• Tape measure, string line, pegs, canes
• Long spirit level and a line level
• Spade, mattock, rake, wheelbarrow, bucket
• Rubber mallet, club hammer, bolster chisel
• Plate compactor (usually hired)
• Gloves, safety glasses, dust mask, kneepads

The Day Before You Dig

Re-mark the route with string and walk it in both directions. Confirm your utility checks are still valid, check the weather forecast and decide where the spoil is going — dug soil fluffs up and takes noticeably more space than the hole it came from, so have a plan for it or a bag on order. Confirm any deliveries, and have your sketch and measurements to hand rather than in your head.

Then start early, dig in stages, and check your levels as you go instead of at the end. A path built on a morning of measuring and a little patience will outlast three built in a rush.
