The phases of a complete landscape project, what happens in each, and where timelines realistically slip — so you know what you're committing to.
A full landscape build is closer to a construction project than to gardening. Knowing the sequence helps you plan around it — and makes it much easier to tell whether a quote you've been given is complete or has quietly left something out.
Phase 1 — Survey and site analysis
Before any design work, the site gets measured and assessed: levels and slope, drainage behaviour, soil type and depth, sun and shade across the day, existing trees worth keeping, and the position of every service line. Skipping this is how projects end up with a patio that floods or a specimen tree planted over a sewer run.
Phase 2 — Design and specification
The design translates how you want to use the space into a plan: circulation, zones, focal points, planting scheme, materials and lighting. Expect at least one round of revisions. This is the cheapest possible moment to change your mind, and the most expensive one to stay quiet about a doubt.
A proper specification lists quantities, materials, plant sizes and species by name. Quotes without one are difficult to compare and easy to under-deliver against.
Phase 3 — Site clearance and earthworks
Clearance, excavation, levelling and drainage. It's the least photogenic phase and often the longest, and it's where hidden conditions surface — buried rubble, unexpected rock, old foundations. Build some contingency into both budget and timeline here specifically.
Every landscape project has one genuine surprise underground. Budget for it and it's an inconvenience; don't and it's a crisis.
Phase 4 — Hardscape
Paving, walls, steps, pergolas, water features and edging — all the built structure. Hardscape goes in before planting for the obvious reason that heavy materials and machinery would otherwise be dragged across finished beds.
Irrigation mains and lighting cable are laid during this phase too, while trenches are already open. Retrofitting either afterwards means lifting work you've just paid for.
Phase 5 — Soil preparation and planting
Topsoil is brought to final levels and amended, then planting runs largest to smallest: trees first, then shrubs, then groundcover and lawn last. Getting good soil in at this stage is far cheaper than trying to improve it later around established roots.
Phase 6 — Establishment
The phase most people don't plan for. New planting needs consistent attention for its first full year — regular watering, staking checks, early weed control, replacement of anything that fails. A garden handed over and then left alone for two months in summer will lose plants, however well it was built.
Realistic timelines
- Small residential garden: 3–6 weeks on site, plus 2–4 weeks of design beforehand.
- Large residential or estate: 2–4 months, often phased around other construction.
- Commercial or campus: 3–9 months, usually delivered in sections so parts open early.
Weather is the main variable. Heavy monsoon rain stops earthworks and hardscape entirely, and extreme summer heat restricts what can safely be planted. Scheduling the planting phase for autumn, where the programme allows, gives everything the best possible start.
