$10,120 — 9.1 m of ramp and landings for a 480 mm rise, at 1:14, in modular aluminium.
The Rise · drawn to scale
Which door doesn’t change the price. The rise and the run do.
A 480 mm rise, drawn at 1:14 as a straight run in modular aluminium. The ramp itself is 6.7 m long; with a 1,200 mm landing at the top and another at the bottom, the whole thing takes 9.1 m of your 10.0 m. Two landings. Total $10,120.
AS 1428.1-2009 · 1:14 max ramp gradient · 9.0 m max flight · 1,200 mm landings · 1,540 mm change of direction · below 190 mm it is a step ramp at 1:10, below 35 mm a threshold ramp at 1:8
Equal scale in both axes, always. Stretch the height and a 1:14 ramp looks like a 1:6 one — the oldest trick in the trade, and the reason people are surprised by the quote and surprised again by the fence they’ve lost. Everything above is drawn at one scale, both ways.

What it costs
Supplied, fitted and made good. Rates are per metre of ramp run — the sloped part — and the landings are priced separately because they are the part people forget. Everything sits inside a $650 minimum for a visit.
Up to 35 mm of sill — a door track, a shower hob, a single tile step. AS 1428.1 lets a threshold ramp run at 1:8, so 35 mm is 280 mm of ramp. Aluminium, screwed and sealed, done in an hour.
One step, or a low porch lip. At this rise AS 1428.1 lets it be a step ramp at 1:10 — no handrails, no landings, no engineering. A 160 mm step is 1,600 mm of ramp.
Bolted, non-slip GRP decking, no footings, and it comes out cleanly when it is no longer needed. The usual answer for a rental or a discharge next week.
Broom-and-seal non-slip finish, edge-thickened, tied into your path. Permanent, silent underfoot, and it lifts the house’s resale.
1,200 mm top and bottom, every time — that’s the standard, not an upsell. A 1,540 × 1,540 landing where the ramp turns back on itself.
865–1,000 mm, continuous, with the 300 mm extensions top and bottom. Kerb rails to stop a castor going over the edge.
Demo reviews
“Mum’s discharge was the Thursday. They came on the Monday, drew the verandah at 1:14 on the spot, and told us the front was 400 mm too tight but the side path wasn’t. Ramp was in on the Wednesday.”
Ngaire T.Bayswater · 520 mm rise, side path, aluminium
“My plan manager had knocked back two quotes because they didn’t match the OT report. This one had the gradient, the landing sizes and the handrail metres on separate lines. Approved first go.”
Dev R.Morley · NDIS home modification, concrete ramp
“I’d been quoted for a four-metre ramp I had nowhere to put. They measured the step at 30 mm, said it wasn’t a ramp job at all, and fitted a threshold ramp for the minimum. Honest people are rare.”
Suzanne M.Maylands · café entry, 30 mm sill
Where we work
We keep the van inside about twenty minutes of Bayswater so a measure-up is a same-week job, not a fortnight’s wait. Outside this ring we’ll still come — we just tell you honestly when.
The dashed ring is about twenty minutes from the Bayswater yard.
Book a measure-up
A measure-up is free and takes twenty minutes. We’ll measure the rise properly with a level and a straight edge, check what you’ve got to the fence, and leave you a drawing and a fixed price. If a compliant ramp won’t fit, we say so at the door — not at handover.
On a real build this lands in the diary with your rise, your setback and the drawing attached, and Rob rings you inside four working hours to book the measure-up.
If there’s a discharge date on it, say so on the phone and we’ll bring the ramp forward.
This is a demonstration page. Nothing was sent, no data left your browser, and the confirmation you’re reading was drawn locally.
The OT report if there is one, a rough idea of the discharge date, and somewhere we can stand a 3 m straight edge. If the house is a rental, the owner’s name — a modular ramp comes out clean, but the agent still wants to know.
Free measure-up · fixed price in writing · no deposit until you’ve seen the drawing
A threshold or step ramp is usually same-week. A modular aluminium ramp is one to two weeks from deposit. Poured concrete is three to four, because the slab has to cure before anyone puts weight on it — there is no version of that we can rush.

Questions we get
AS 1428.1-2009 — the Australian Standard for design for access and mobility — sets 1:14 as the steepest gradient a ramp may be built to, with a maximum flight of 9.0 m before a landing. It is not a comfort figure. It is roughly the limit at which an average person can self-propel a manual wheelchair up a slope and, more importantly, control the descent. The Disability (Access to Premises) Standards and NCC Volume One Part D4 both point back at it for commercial work, and it is what an NDIS home modification gets assessed against.
1:14 is the ramp figure, and the standard is stricter than most quotes admit about what is and isn’t a ramp. Under 190 mm of rise it is a step ramp, capped at 1:10 — a 160 mm step gets 1,600 mm of ramp. Under 35 mm it is a threshold ramp, capped at 1:8. Neither needs handrails or landings, which is why both are flat-priced above. The 1:8 gradient with a 1,520 mm maximum length that gets quoted at step ramps all over the trade belongs to a kerb ramp — the wedge at the end of a footpath — and it does not apply to a step at your front door. Built to that figure, the same 160 mm step comes out 1,280 mm and is too steep.
Our name is the number. If we can build you one in fourteen, we will. If we can’t, you get told why on the first visit.
A 1,200 mm landing top and bottom, always — you need somewhere flat to open a door and somewhere flat to stop at the bottom. Those two are in every ramp price on this page and they are why the run and the footprint are different numbers.
After that it depends on the gradient. At 1:14 you get 9.0 m of flight before an intermediate landing is required; at 1:16 it’s 12.0 m. At 1:20 it is technically a walkway rather than a ramp, and no intermediate landing is required at all — which is why a 1:20 answer sometimes ends up shorter overall than a 1:16 one even though the slope is gentler. Fold the ramp back on itself and the turn needs a 1,540 × 1,540 landing so a wheelchair can actually get around it.
Then we tell you, on the page above and on the day, and we don’t build it. A 1,200 mm rise wants 20.4 m of ramp and landings at 1:14 in a straight line. Folded as a switchback at 1:16 that comes down to 13.1 m. If you haven’t got 13.1 m, no arrangement of a compliant ramp fits your house.
A non-compliant ramp is worse than nothing: it fails at handover, it doesn’t get funded, and someone still has to get down it. What you want at that point is a platform lift or a through-floor lift. We don’t install them and we don’t take a commission on them — we’ll give you two names and get out of the way.
They don’t change our rates. What they change is the paperwork. Anything structural under the NDIS home-modification framework needs an occupational therapist’s recommendation and a registered building practitioner doing the work, and the quote has to line up with what the OT actually wrote — gradient, landing sizes, handrail type, surface finish, all of it on separate lines rather than one lump sum. That is the single most common reason a home-modification quote gets sent back.
We are not occupational therapists and we don’t write the report. We read yours, we quote to it, and if we think the OT’s recommendation won’t build we ring them, not you.
Modular aluminium at $780 a metre of run is bolted together on adjustable feet, needs no footings, goes in over a day or two, and comes back out cleanly. It is the right answer for a rental, for a discharge next week, and for anything you hope is temporary.
Poured concrete at $1,150 a metre of run with a broom-and-seal non-slip finish is silent underfoot, will not move, and reads as part of the house rather than as equipment bolted onto it. It’s the right answer for a home someone intends to stay in. It also takes three to four weeks because the slab has to cure.
We don’t install platform lifts, stair lifts or through-floor lifts. We are not occupational therapists and we won’t write you a report. We don’t do bathroom modifications beyond a threshold ramp at the shower hob. And we won’t build a ramp steeper than 1:14, at any price, for any deadline — not because we’re precious about it, but because it is the one thing on this page that cannot be undone once the concrete is off the truck.
