Who they are
A family modular builder from Warwick on the Darling Downs. Jim Westerman founded Westbuilt in Warwick in 1993, delivered the first Westbuilt modular home at Stanthorpe in 1994, moved to relocatable homes only in 2003, and opened a new Warwick factory in 2012 to build custom modular homes for Queensland and NSW clients. His sons now run it: David Westerman is Managing Director, Michael Westerman General Manager and Rick Westerman a Director.
They state more than 70 staff across Warwick and Loganholme. The factory is at 38 to 48 Project Street, Warwick; head office and a display village are at 485 East Street, Warwick, with a second display village at 3938 Pacific Highway, Loganholme. Their prefabAUS profile gives a production capacity of 80 homes a year.
The company is Active Construction Group Pty Ltd (ABN 40 165 638 988), which trades as West Built Homes on the QBCC register.
What they make
Full-size, custom-built modular homes rather than granny flats. Their designs page lists 50 plans in three ranges, and the site also names a Seaside range and a Government and Commercial range. Their pricing page sets out three inclusion tiers: Silver, Gold and Platinum.
| Range | Designs listed | Floor area | Bedrooms | Examples |
|---|---|---|---|---|
| Signature | 5 | 240 to 423 m² | 3 to 5 | Burbank, Burleigh, Noosa |
| Acreage | 32 | 109 to 357 m² | 2 to 5 | Moreton, Ascot, Samford, Hamilton, Bangalow, Glenvale, Maleny |
| Rural | 13 | 108 to 218 m² | 2 to 5 | Adavale, Alpha, Diamantina, Winton |
The smallest plans on the list:
| Design | Range | Floor area | Bedrooms | Bathrooms |
|---|---|---|---|---|
| Winton 108 | Rural | 108 m² | 2 | 1 |
| Emerald 109 | Acreage | 109 m² | 2 | 1 |
| Alpha 113 | Rural | 113 m² | 2 | 1 |
| Moreton 121 | Acreage | 121 m² | 2 | 1.5 |
| Bangalow 124 | Acreage | 124 m² | 2 | 1 |
| Samford 127 | Acreage | 127 m² | 2 | 1 |
Display homes: the Glenvale at Warwick (Acreage range), and the Hamilton and Moreton at Loganholme. Virtual tours cover the Glenvale, Moreton and Adavale. You can book a factory tour at Warwick.
How they build
- Frame: light gauge steel, which they cite for weight, cost, termite resistance and fewer defects. Their prefabAUS profile names the FRAMECAD steel framing system.
- About 80% of each home is completed in an ISO-accredited factory, then moved in sections or modules and finished on site.
- Modules are trucked to site and positioned by an axle system or a crane, depending on location.
- Termite protection is a physical barrier of steel posts and subfloor, with structural timber at least 450 mm above ground.
- Designed to the current NCC and Australian Standards, with a stated 50-year design life.
- Energy: no star rating is stated. They don't offer net-zero or passive homes; extra insulation, solar and double glazing are options.
- Cyclone rating is optional, priced by home size and location.
- Homes can go on unserviced sites with tanks, solar or septic arranged.

What's included, and what sits on top
| Item | As Westbuilt publishes it |
|---|---|
| Transport | Fixed delivery price. Included within 200 km of Warwick; beyond that, priced on location and module size |
| Crane or axle placement | Used as the site needs; their site doesn't say how it's priced; ask |
| Footings | Their site doesn't say; ask. Engineering and soil tests are arranged in the design stage |
| Building and plumbing approval fees | Included |
| Development approval (for example a second dwelling) | Extra, $4,000 to $10,000 depending on council |
| Service connections | See below |
| Floor coverings | Included: tiles in wet areas, carpet in bedrooms, vinyl in living and hallway |

On connections their pages differ. The pricing FAQ lists on-site connections as excluded and variable. The general FAQ puts them at typically $10,000 to $50,000 and says their on-site team arranges them at no extra cost. The process page says the final fixed price includes service connections as standard unless you ask otherwise. Ask which applies to your quote, in writing.
Where they deliver
Queensland and northern New South Wales, including several Moreton Bay islands. Transport within 200 km of Warwick is in the standard price; further out, it's priced on location and module size.
Warranty and licence
Westbuilt states a 12-month minor defect warranty and a 10-year structural warranty.
Active Construction Group Pty Ltd holds QBCC licence 1284758, Builder Open, active, trading as West Built Homes, financial category 5, with no condition recorded (register searched 14 October 2026). Their site also shows NSW builder licence 266388C for work across the border.
Getting one into the ground in Queensland
Westbuilt runs most of this itself: site inspection, approvals, transport and on-site assembly. The steps still apply, and the block check matters most on acreage:
- Block check. Confirm the lot size, zoning, overlays (flood, bushfire, character), easements and sewer position before you sign for a home. This decides where the home can sit and what approvals you need.
- Approval. A secondary dwelling needs building approval from a private certifier, and some blocks also need council planning approval. Allow for a soil test, engineering and an energy report.
- Footings. Piers or a slab designed by an engineer for your soil class and wind region, set out by a surveyor, and inspected before the home lands.
- Transport and access. The truck needs a clear route to the site, and either a crane pad with room to swing or a level run for a trailer. Overhead power, trees and side setbacks are the usual problems.
- Connections. A licensed plumber and electrician connect sewer, water, stormwater and power. Long runs, pump stations and meter upgrades cost more.
- Final inspection. The certifier signs off once the home is fixed down, connected and compliant, and issues the final certificate.
- Home warranty. In Queensland, residential building work over $3,300 needs a QBCC licensed contractor, and the licensed contractor takes out QBCC home warranty insurance for insurable residential work. Know which company holds it for each part of the job.
On rural blocks, add access for a long load, bushfire and flood overlays, and on-site water and wastewater to the block check.
Questions to ask them
- Are service connections in my fixed price or not?
- Are footings, crane and site levelling in the contract sum?
- What does transport cost to my address if it's over 200 km from Warwick?
- Which inclusion tier is the $392,000 Bangalow 124 price?
- Is the consultation fee credited if I go ahead, and refunded if I don't?
- Does my block need a development approval, and who engages the town planner?
- What date is the contract handover, and what happens if it slips?
- How many modules will my design be, and what access do they need?
- What does the 10-year structural warranty cover, and who holds the home warranty insurance?
- Can I see a home of my design at Warwick or Loganholme, or a finished client home?
Who they suit
Queensland and northern NSW buyers, especially on acreage and rural blocks, who want a full-size family home built in a factory by a family firm with 30-plus years in modular, a published process with costs at each stage, and one builder from design to handover. For a small backyard granny flat, their smallest plan is 108 m², so it's a different size of product.
