Designed and engineered by us. Delivered as a kit, at lock-up, or finished.
We design and engineer the whole building — structure, envelope, interior. You choose how much of it arrives already done: an engineered kit delivered to your site, the building complete to lock-up, or a finished home craned onto your footings. Same drawings, same engineering, every way.
I knew what I was getting and what it would cost before anything was built. The Studio turned out better than the renders.
Every question got a straight answer. It never felt like we were being sold to, and the design felt like ours.
What sold me was the system. Same drawings, same engineering, whether it goes out as a kit or finished. You don't see that often.
How much of it should we do?
Choose in the configurator and the price follows. Everything you pick carries through to your enquiry.
Price your home in 2 minutes.
Pick a layout, choose how much of it we do, and see the price as you go.
- Complete. Built in the factory and craned onto your footings. You walk in.
- Lock-up. The building delivered to lock-up. You finish the inside.
- Kit. The engineered building as a numbered kit. You or your builder put it up.
Six steps, and you can stop at any of them.
Nothing here commits you to anything. You can go as far as you like on your own and hand the rest to a consultant.
-
01
Start with a shape
Pick one of our plans. If none of them fit, Arc Studio designs one for you on the Arc system, and half the design fee is credited against a Modular build or Lock-up Supply contract.
-
02
Choose how it's delivered
Kit, lock-up or complete. It's the one real decision, and you can change your mind at any point before you sign.
-
03
Configure it and see the price
Bedrooms, width, length, finishes. The price updates as you go, so you are never guessing what a change costs.
-
04
Pick your interior optional
Your kitchen is already specified, so it is just your internal doors and your floor in Arc Elements. Skip it if you would rather not decide yet — your consultant will walk through it with you.
-
05
Tell us about your site
Four short questions about approvals, who installs it, footings and services. Answer what you know and leave the rest blank.
-
06
Send one enquiry pack
Everything above arrives with us in a single pack, so the first conversation starts from your actual building instead of a blank page.
Know what it costs before you speak to anyone.
Most people spend months and a few thousand dollars before they find out a project does not stack up. You can find out in about two minutes, at your kitchen table, without a salesperson in the room.
- 01 Build your plan. Bedrooms, module widths, lengths, finishes and exterior colour — laid out as you change them.
- 02 Both prices, side by side. Delivered complete and kit, updating together, so you can see exactly what the labour is worth to you.
- 03 Leave with a pack. Your configuration, your interior selections and your site answers, all in one document a consultant can act on.
Free, no login, nothing sent until you press send. Prices are indicative estimates, not a quote.
How long does it take?
Two to three minutes for a price. Ten if you do the interior selections and the site questions as well and send the whole pack.
Do I need to know my block yet?
No. You can price a building without knowing anything about your site. The site questions are stage five and you can skip them — a consultant will work through them with you instead.
Can we customise the internal layout?
Yes. The building carries its load on the perimeter and on portal frames, so no internal wall is structural — the layout inside the external walls is yours to change. The perimeter and the wet areas stay put, which is what lets us engineer and price it repeatably.
Widths of 5.0 m and 6.0 m go further: those are supplied as a clear open span with the layout drawn with you from the start. They're kit supply only, because nothing wider than 4.5 m can be transported finished.
What if I do not like any of the plans?
Arc Studio designs one for you on the Arc system, and half the design fee is credited against a Modular build or Lock-up Supply contract.
Am I committing to anything?
No. Nothing is sent until you choose to send it, and the pack is a starting point for a conversation rather than an order.
How it goes together.
Twelve steps, drawn from the amended general arrangement and the assembly model, in the order the building actually goes up. Click, drag, or use the arrows to step through — or just scroll straight past.
01 / 12
Footings and base beams
The footings are set, then the 200PFC base beams are bolted down to form the perimeter the whole frame is set out from.
Step 1 of 12
Every connection bolts. No welder needed on site.
What the same frame carries once it is clad
Visualisations, not photographs.
Four systems. One building.
These are not four things to choose between. Studio gets you a plan, Modular or Kit Systems delivers the building, Elements finishes the inside. Take as many of them as you need — or go straight to any one of them.
Studio
Design and documentation. Concept drawings through to DA/CDC, with 50% credited against a Modular build or Lock-up Supply contract.
Explore Studio 02Modular
Class 1A certified dwellings, built in a factory and craned onto your site. Fixed price, published inclusions.
Explore Modular 03Kit Systems
The engineered PFC steel kit — the complete structure, inside and out. Bolted on site, welded off it.
Explore Kit Systems 04Elements
The interior fit-out system. One 7 mm reveal, carried through doors, wall panels and cabinetry.
Explore ElementsThe things people ask before they call.
Where an answer isn't confirmed, it says so rather than guessing.
Is this a kit home?
Arc works in three areas. Building Systems is a kit: prefabricated steel weldments that bolt together. Modular is the dwelling that sits on it. Design Studio is the design and documentation side. You can buy the frame alone.
Who builds it?
Who fabricates the steel, who erects the frame, and who holds the build contract all vary by project — ask on your call.
Does it get council approval?
Not answered here. Approval pathways differ by state and council and Arc has not confirmed what it supplies towards an application.
What sizes are possible?
Length runs on the portal grid: portals sit at 4.0 m centres at most, so the bay count is the length divided by four, rounded up.
Width runs on the section ladder: up to 3.5 m uses a 180PFC portal, 3.5–4.5 m a 230PFC, 4.5–6.5 m a 250PFC, and 6.5–8.0 m a 300PFC. Base beams stay 200PFC.
Beyond one module, modules join side by side, mirror, and link with a breezeway. The reference building shown here is two modules of 3.5 × 8.0 m, 56 m², over two bays.
How is it engineered?
Portal frames in PFC. Base beams 200PFC. Posts and rafters at the reference building are 180PFC. Connections are made through 10 mm and 12 mm plates with 16×50 and 20×60 MHSA bolts. Plates and cleats are welded on in the shop.
On site nothing is cut, welded or measured — the members are bolted where the plates already are.
What is and isn't included?
Building Systems is the structural kit. Modular is the dwelling on the grid. Design Studio is the design and documentation that sits in front of both.
The exact boundary of each area — footings, services, cladding, wet area waterproofing, appliances — varies by project and is confirmed on your call.
What does it cost, and how long does it take?
The build-your-own configurator above gives an indicative starting-from price by area, but it isn't a quote. Modular runs to roughly 16 weeks contract to keys; exact cost and timing depend on size, finish and site — ask on your call.
What happens after the call?
A design and engineering phase, then a contract, then the frame goes into fabrication. See the Modular page for the full six-step process from contract to keys.
One pack. Everything you’ve chosen, in one place.
Rather than a blank contact form, you send us the actual building. Whatever you have decided comes with it:
- Your plan — ours or your own.
- How you want it delivered, and the indicative price for both routes.
- Your interior selections, if you made any.
- What you know about your site: approvals, install, footings, services.
Anything you have not decided stays blank, and we work through it with you. Nothing in the pack is a commitment.
What happens next
- We read the pack before we call you, so you are not starting from scratch.
- A consultant comes back within two business days with what it would take to price properly.
- If you want, we book thirty minutes to walk through it.
Takes a couple of minutes. Goes straight to sales@arcmodular.com.au — no email app needed.
