A private green is the ultimate garden upgrade, and the exact craft that built ibuild’s reputation. Here is how a tour-quality green comes together, step by step.
Building a green that truly rolls is engineering, not carpet-laying. These ten steps are the same process behind our landmark work, scaled to a home garden.

Pick a spot with reasonable sun and drainage and enough room for a run-up. Even a compact corner can hold a two- or three-cup practice green.
Decide the shape, the number of cups, and where the breaks and tiers go. This is where a green is won or lost; we preview contours in 3D before a spade goes in.
Dig out the turf and topsoil to depth so the finished green sits flush with the surrounding ground and has room for the sub-base.
Lay and compact crushed aggregate in layers. In Singapore this drainage-led base is what clears a monsoon downpour in seconds and stops the green ever sitting wet.
Sculpt the humps, hollows and tiered pin areas into the base itself, so putts read genuine slope. Break is built in here, never faked in the turf.
Position regulation 4¼-inch (108 mm) cups on the flat, never mid-slope, with the rim sunk flush so nothing catches the ball.
Roll out dedicated short-pile putting turf, cut it to the green’s shape, and join seams invisibly so the surface reads as one continuous green.
Brush in rounded kiln-dried silica at a controlled depth. This weights the pile, holds green speed and keeps the roll true, plain building sand compacts and kills the roll.
Frame the green with a longer, darker chipping fringe so you can practise chips and run-ups onto the surface, and to define the edge cleanly.
Brush and dress until the Stimpmeter reading matches how you want to practise, around 8–10 suits most home greens: quick and true without being punishing.
We design and build true-rolling greens for gardens, rooftops and balconies, the same craft behind our tour-quality landmark work.
