A synthetic putting green is a groundworks project with a specialist turf on top. The ball rolls true because the base beneath it was excavated, drained, compacted and shaped correctly. The turf finishes the job rather than doing it.
Cost is driven by contours, drainage and access far more than by the turf itself, which is why a green is quoted from a site visit rather than a rate per square metre.
What Decides Whether a Green Plays Well
The turf is a 14mm putting pile, not lawn grass.
Golf-Putt 14mm is the surface built for this. Landscape turf at 35mm will not roll a ball.
The base is the green.
Every inconsistency in how a ball rolls on a finished green was built into the ground underneath it.
Contours are what make it worth having.
A dead flat green is easy to build and dull to play, because every putt is the same putt.
Fringe turf is a separate decision.
Approach and surround areas use a different product from the putting surface itself.
Drainage is a legal question as well as a practical one.
Re-grading a backyard changes where water goes, and you cannot push it onto a neighbour.
No published price, and that is the honest position.
A small flat green and a multi-contour design sit at opposite ends of a budget.
How Do You Choose the Right Synthetic Putting Green?
Start with how you will actually use it, not with how big the yard is.
A green built for a scratch golfer and a green built for a family that also wants somewhere to sit are different projects with different budgets.
Available space and shape.
A compact courtyard and a wide backyard call for different layouts, and shape matters more than raw area.
Number of cups.
Two cups on a modest green give you far more practice than one on a larger one, because they multiply the lines you can putt.
Flat or contoured.
This is the single biggest decision, for both play value and cost.
Putting distances you want.
Length matters more than width. A long narrow green beats a square one of the same area.
Whether you want a fringe or chipping area.
This adds a second turf product and a second area of base.
Existing slope, drainage and access.
These decide how much groundwork the project needs before any turf is ordered.
Plan the cup positions before anyone excavates.
Cups want a reasonably flat approach and enough green around them to give you more than one line into the hole. Deciding where they go after the base is shaped is how people end up with a green that only breaks one way.
Think about sun and shade at the same time. Synthetic surfaces run considerably hotter than natural grass in direct sun, so if the green is somewhere the family will stand around on a February afternoon, an exposed north or west aspect is worth knowing about before you dig.
What Turf Does a Synthetic Putting Green Use?
A short, dense putting pile.
Ordinary landscape turf sits at 30mm to 45mm and is built to look like a lawn. A ball will not roll on it, because it sinks into the pile instead of sitting on top.

Most backyard greens use at least two products.
Golf-Putt for the surface you putt on, and a landscape pile for everything around it. That contrast is also what makes a green read as a green rather than as a patch of short grass.
The complete system, in this order: base, contours, turf, infill.
A premium turf over a poor base will play inconsistently. A well-built base under a mid-range turf will surprise people.
A compacted, free-draining base built in layers.
A coarse layer for structure, a fine screening layer on top that can be shaped and screeded. Compacting a single deep lift firms the top and leaves the bottom loose, which is how soft spots appear six months later.
Contours shaped into the base, not the turf.
The breaks a ball reads are cut into the fine layer before anything is laid.
Consistent pile direction.
Every piece on a green must run the same way. A section laid against the grain rolls differently from the rest and cannot be corrected afterwards.
Joins that are invisible to the ball.
Not just to the eye. A finished seam should be tested by rolling a ball across it from several angles.
Cups set flush with the surface.
A cup sitting proud rejects good putts, and one sitting low collects water.
Infill brushed in evenly.
On a green the infill also affects speed, so it goes in gradually rather than all at once.
Secure perimeter edging.
Keeps the turf tight and the edge clean where the green meets paving or a garden bed.
Green speed is not a specification you order.
It is a result of pile, infill level, contour and how the surface is maintained, which is why a good installer will ask how you play before recommending anything rather than quoting a number off a chart.
How Much Does a Synthetic Putting Green Cost?
A1SGS does not publish a fixed installed price for putting greens, and no honest one exists.
A green is not priced like a lawn, because the shaping and drainage work can cost more than the turf.
What moves the number:
What drives the cost of a backyard putting green
Driver
Effect on the quote
Contouring
The largest single variable. Shaping and testing breaks is skilled, slow work.
Drainage
A site that already puddles needs solving before turf, and that is groundworks.
Excavation and spoil removal
Depth, soil type and where the excavated material goes.
Site access
A narrow side gate turns a machine job into a wheelbarrow job.
Green size and shape
Larger areas reduce the cost per square metre. Complex shapes increase cutting and waste.
Number of cups
Each one is a separate cut, excavation and finish.
Fringe and surrounds
A second turf product and a second area of prepared base.
Removing what is there now
Lawn, paving or a garden bed all have to go somewhere.
Do not compare quotes on the turf rate.
A quote that is cheaper per square metre and vague about base depth, drainage and compaction is usually cheaper because it is doing less groundwork, and groundwork is the part that decides whether the green still rolls true in five years. Ask for the base to be itemised.
The guide to what artificial turf costs
covers the factors common to any installation. A putting green adds shaping, cups and finishing on top of those, so a standard residential turf rate should not be read as a putting green price.
What Is Involved in the Installation?
Site assessment.
An installer reviews the existing ground, drainage, access and available space, and talks through the layout you have in mind. This is also where the number of cups and the amount of break get decided.
Design and layout.
Shape, putting distances, cup positions, slopes and any fringe area are planned against the realities of the site rather than a catalogue picture.
Ground preparation.
Existing surface removed, area excavated, subgrade levelled, drainage installed or integrated. Underground services are located before any digging starts.
Base construction.
Coarse layer laid and compacted, then a fine screening layer laid and compacted separately, with levels checked against a string line or laser rather than by eye.
Shaping the contours.
The breaks are cut into the fine layer and tested with a ball before anything covers them.
Turf installation.
Golf-Putt positioned, allowed to relax, cut to the shape of the green, joined and secured, with pile direction consistent across every piece.
Cups and finishing.
Cups cut in and set flush, checked with a straight edge, then edging, fringe and any surrounding turf.
Infill and brushing.
Infill spread and brushed in, fibres brought upright, roll tested and adjusted.
Final inspection.
Seams, edges, drainage, cup levels and ball roll all checked from several directions before handover.
Think about where the water goes, not just that it leaves.
Re-grading part of a backyard changes how the whole yard sheds water. Central Coast Council is explicit that owners must not divert, redirect or concentrate stormwater from its natural path onto neighbouring properties, and that anyone creating a hardstand area has to control the runoff it produces. If the site already holds water after rain, that gets solved at the excavation stage, because there is no fixing it once the turf is down.
DIY or Professional Installation?
A small flat green with one cup is a realistic DIY project.
If you are comfortable with excavation, compaction and cutting turf accurately, and you are honest about the tools you have, it can be done well over a couple of weekends.
Contours are where DIY greens come unstuck.
Shaping a break that reads correctly, and doing it consistently across a whole surface, is a skill rather than an instruction, and mistakes are only visible once the turf is down and expensive to correct at that point.

Best suited to
Small, flat, single cup
Contoured, larger, multi-cup or performance greens
A green needs less than a natural one and more than a lawn, because anything on the surface changes how a ball behaves.
Clear leaves and debris regularly.
A single gum leaf on a putting line will move a ball off it.
Brush the pile
along the lines people putt from and around the cups, where fibres flatten first.
Top up infill
where you can see it has thinned or migrated, particularly around cups.
Hose the surface
to flush grit out of the pile before it works down into the base.
Check seams and edges
for lifting or separation.
Keep cups clear
of sand, leaves and water.
Watch the drainage points
and clear anything blocking them.
The areas around the cups need the most attention.
That is where feet land, where balls are retrieved and where infill migrates, and it is the first place a green starts to play unevenly.
Frequently Asked Questions
What is a synthetic putting green?
A synthetic putting green is a purpose-built artificial surface designed for consistent ball roll rather than for appearance. It uses a short, dense putting pile, typically around 14mm against 30mm to 45mm for landscape turf, laid over a shaped and compacted base. A1SGS uses Golf-Putt 14mm for the putting surface, with a landscape pile for the fringe and surrounds. What makes it play well is the base and contouring beneath the turf, not the turf alone.
How much does a synthetic putting green cost?
There is no fixed price, because contouring, drainage and site access drive the cost more than the turf does. A small flat green with one cup and a large multi-contour design sit at opposite ends of a budget even at similar square metreage. Excavation depth, spoil removal, the number of cups, fringe areas and access all move the figure, so a green is quoted from a site visit. Be cautious comparing quotes on the turf rate alone, since the cheaper rate often means less groundwork.
How long does a synthetic putting green last?
A1SGS turf carries a minimum eight year product warranty, with a 24 month workmanship guarantee on the installation. Actual lifespan depends on the base underneath, how often the green is played, UV exposure and whether infill is topped up and the pile brushed. A well-built green on a properly compacted base routinely outlasts its warranty, and a premium surface on a poor base does not.
Can you build a synthetic putting green yourself?
Yes, for a small flat green with a single cup, if you are comfortable with excavation, compaction and accurate cutting. Contours are where DIY greens usually come unstuck, because shaping a break that reads correctly across a whole surface takes practice, and errors only become visible once the turf is down. Drainage work, multiple joins and precise speed expectations are the other signals to call an installer.
Do you need infill on a synthetic putting green?
Yes. On a green the infill supports the fibres and also influences how fast and how consistently the ball rolls, which makes it a playing decision rather than just ballast. It goes in gradually, brushed between coats and tested with a ball, because adding more is far easier than taking it back out. Topping it up where it has migrated is part of routine maintenance.
