Backyard renovation: order, budget and who does what

A backyard renovation runs in five stages, and they only work in one order.

First, access and demolition: getting machines, skips and material in and out, and taking out what is going. Second, levels and drainage: cut, fill, falls, soakaways, any pipe or sleeve that runs under something. Third, hard landscaping: walls, steps, patios, paths, decks, footings for structures. Fourth, planting: soil improvement, trees, shrubs, turf. Fifth, lighting, irrigation and finishing.

Each stage buries the one before it. That is not a stylistic preference, it is the reason order controls cost. Planting a border and then discovering that a digger still has to come down that side of the yard means paying twice — once for plants that get crushed, once for the labour of doing by hand what a machine would have done in an afternoon.

Contractors sequence this instinctively. Homeowners phasing a job themselves routinely do not.

The single most underestimated line in a backyard renovation quote is how the material gets to the back of the house.

RitchieSpecs lists the Kubota K008-3, one of the smallest tracked excavators on the market, at 2.3 feet across the tracks, 2,200 lb operating weight and 5.63 feet of digging depth. At 2.3 feet, or roughly 28 inches, that machine walks through a standard 900 mm side gate — about 35 inches — with inches to spare. A 1.5 or 3 tonne machine, which is what most contractors would rather bring, does not.

So the gate width sets the method. Machine access means bulk deliveries, a machine doing the digging and spoil leaving by grab lorry. Barrow-only access means every yard of soil out and every pallet of stone in travels by hand down a narrow passage.

Measure the narrowest point on the route, at the narrowest height, before you take a single quote. That number changes labour more than the choice between concrete and sandstone ever will.

Levels and drainage are invisible in the finished garden and are the stage most often cut to make a budget work.

HomeGuide puts land leveling at $0.40 to $2.00 per square foot, with leveling a small area for a patio at $500 to $1,000 and reworking a whole sloping backyard at $1,000 to $5,000. Those are among the cheapest numbers on the whole project, and they are the ones that decide whether the rest of it survives.

Everything downstream sits on this. Falls have to run away from the house. Paving needs a crossfall or it holds water. A lawn on ground that ponds becomes moss inside two seasons. Any pipe, sleeve or conduit crossing under a future patio has to be laid now, in an open trench, rather than later through 400 square feet of finished stone.

Skipping this stage does not save the money. It defers it into a repair that also costs the surface above it.

Surfaces and structures dominate a backyard renovation budget, usually by a wide margin.

HomeGuide's 2026 figures put landscaping overall at $4 to $12 per square foot, a patio at $5 to $35 per square foot installed with concrete at the bottom of that band, a deck at $25 to $50 per square foot, with composite at $40 to $80 and a retaining wall at $35 to $65 per square foot. Those were read from indexed page text on August 3, 2026.

Run the arithmetic on a modest job. A 400 square foot patio in mid-range stone sits in the same money as several hundred plants. A single retaining wall can absorb a third of a five-figure budget on its own.

This is why the size of the paved area is the strongest lever a homeowner has. Shrinking a terrace by a quarter changes the total more than switching material ever does, and it is a decision made on paper for free.

Planting is almost always the smallest line on a backyard renovation, and it is reliably the first thing cut when the quote comes back high. That is backwards.

HomeGuide puts a landscaper at $25 to $85 to plant a shrub and new sod at $1 to $2 per square foot, or $1,000 to $3,000 for a typical yard. Against $35 to $65 per square foot for a retaining wall, forty shrubs is a rounding error.

Planting is also the only element that improves on its own. Stone looks its best on the day it is laid and slowly weathers; a border looks thin for two seasons and then, at three to five years, looks like the reason the project happened at all.

Cut the paved area before you cut the planting budget. The saving is larger, the regret is smaller, and beds are the one thing you can genuinely add to later without disturbing anything.

Phasing a backyard renovation across two or three seasons is sensible. Phasing it in the wrong groups is how people spend more than doing it all at once.

The rule is simple. Anything that needs machine access, and anything that lives under a hard surface, goes in one phase. That means excavation, spoil removal, regrading, drainage runs, footings, and every conduit, sleeve and irrigation line that crosses under future paving. A second machine mobilisation, and the re-lifting of paving to reach a pipe, are the two costs that make phasing expensive.

What waits comfortably: planting beds, turf, the fire pit, the pergola on pre-poured footings, the outdoor kitchen on a slab you already laid, fencing, and every light on a cable you already ran.

Phase one is dirt and stone. Phase two is green. Phase three is furniture and finish. Grouped that way, a three-season job costs roughly what a one-season job costs.

Lighting is the last stage to be installed and the first that has to be decided.

HomeGuide puts outdoor lighting at $80 to $300 per fixture, or $800 to $6,000 for a scheme including labour, with low-voltage fixtures at $100 to $150 installed. Those numbers assume a cable route exists. They do not describe the cost of cutting a trench through a finished terrace, which is a different job entirely and prices like demolition.

So decide the fixture positions during the levels stage, even if you do not buy a single light for two years. Lay conduit under every hard surface it might one day need to cross, cap the ends, and photograph the runs with a tape in shot before anything covers them.

The same logic applies to irrigation, outdoor power and any water feature. Empty conduit is the cheapest insurance on the whole project, and the only moment it can be bought is while the ground is open.

Some of a backyard renovation is honest weekend work. Some of it costs more to fix than to hire out.

Genuinely approachable: demolition and clearance, planting and mulching, timber raised beds, gravel paths on a compacted sub-base, fence panels between existing posts, laying turf on ground somebody else graded, and low-voltage lighting that plugs into a transformer.

Hire it out: anything retaining soil, anything carrying a structure, mains electrical work, gas, drainage connections, and large-format paving where a lipped joint or a flat fall is visible forever. Grading is the one people misjudge most — it looks like moving soil, and it is actually setting the falls that every other element depends on.

The honest test is whether a mistake is visible, structural or wet. A crooked gravel path is a Saturday. A patio that falls toward the house is a repair that involves lifting the patio, and no saved labour covers that.

A render has one job on a backyard renovation, and it happens before anybody breaks ground: settling the direction, with the household and with the contractor.

AI Landscape Design, published by Skyble Lab, takes a photo of the yard you already have and returns it redesigned in a chosen style, in about 10 seconds, across 18 styles. It is photo-to-photo, so the house, the fence line and the boundary stay where they are. The first 3 designs are free at full resolution; after that it is $59.99 a year or $7.99 a week.

Be clear about what that is not. A render prices nothing. It checks no grading, measures no gate, reads no setback, and shows planting at mature size rather than at the size it arrives. It cannot tell you whether your falls run the right way.

What it does is stop two people arguing about a garden they are each imagining differently, which is the argument that produces mid-build changes.
