About AOI
We build outside the way good builders build houses.
Most of what goes wrong in outdoor construction goes wrong underground, out of sight, before the parts you can see were ever installed.
The retaining wall that leans came from footings drilled too shallow. The paving that dips came from base laid too thin. The lawn that floods came from levels no one shot and drainage no one designed. By the time it shows, the contractor is long gone.
Adelaide Outdoor Improvements exists because outdoor construction deserves the same discipline as building a house: engineering where loads demand it, a sequence followed in order, materials specified for the site rather than the invoice, and one team accountable for the whole result.
That's why every service page on this site shows you the build sequence stage by stage. We want you to know what you're paying for — including the stages you'll never see again once the job is finished.
01
Design-led
Levels, materials, structure and planting resolved together before work starts — so the finished space is designed, not accumulated.
02
Engineered
Footings, walls, slabs and drainage built to Australian Standards and site-specific engineering, documented for council where required.
03
Accountable
One contract, one team, one point of responsibility from demolition to handover. No gaps between trades, no one to point at.
04
Transparent
Fixed quotes, published rates on bookable work, GST-inclusive pricing, and variations approved by you before they proceed. Always.
Where we work
Adelaide metro and the Hills.
From the coast to the escarpment and up into the Hills — we build across the Adelaide metropolitan area within roughly 50 kilometres of the CBD. Reactive eastern clays, coastal sands, foothill rock: we quote each site on what its ground actually is, because we've built on all of it.
