Towable Solutions for Every Operation
Purpose-built on heavy-duty chassis with full road registration, our mobile units are designed for the realities of regional Australian worksites.
Standard Towable Office
A fully equipped workspace on a registered trailer chassis. Tow it with a standard site vehicle, unhitch, level, and you’re operational. Ideal for civil crews, road maintenance teams, and any operation that relocates regularly.
Towable Office + Amenities
Workspace plus integrated toilet and kitchenette on a single towable chassis. For remote sites where separate amenity hire isn’t practical or cost-effective. One unit, fully self-contained, fully mobile.
Heavy-Duty Remote Trailer Available
Engineered for unsealed roads, pastoral stations, and mining access tracks. Reinforced chassis, off-road rated suspension, and ruggedised exterior for the harshest conditions regional Australia can deliver.
Tow and Go. No Crane Required.
Every Modubuild mobile office is built on a fully engineered, road-registered trailer chassis. Hitch it to a standard site vehicle, tow it to your next location, and be operational within minutes. No crane bookings, no oversized load permits, and no half-day setups. For operations that relocate frequently, such as roadworks, pipelines, or seasonal agriculture, this mobility translates directly to thousands of dollars saved per move and zero lost productivity between sites.
We Build It Mobile - You Focus on the Job
From chassis engineering through to delivery at your first site, we handle every detail of your mobile office build.
Heavy-duty, road-registered trailer chassis engineered for regional conditions
Full interior fit-out-desks, storage, electrical, and optional amenities
Compliance documentation for road transport and worksite standards
Delivered to your first site, ready to hitch and go from day one
Built for sites that move regularly, these units are engineered to handle repeated towing while retaining the strength and durability of a traditional site shed - far more robust than caravan-style offices.
Your Office Should Move as Fast as Your Crew
Stop paying for crane hire every time your project relocates. A Modubuild towable unit pays for itself in saved mobilisation costs within the first few moves.
Built to Tow. Built to Last.
Unlike static buildings retrofitted onto trailers, Modubuild mobile offices are engineered from the chassis up for road travel. Heavy-duty suspension, reinforced connection points, and a low centre of gravity ensure safe, stable towing on sealed and unsealed roads alike.
Inside, every component is secured for transit - no rattling fixtures, no cracked panels after the first rough road. Commercial-grade finishes, air conditioning, LED lighting, and proper insulation mean your crew gets a workspace that’s comfortable no matter how remote the site.
Engineered With Trusted Components
Every mobile unit uses certified chassis components, commercial-grade electrical systems, and Australian-standard materials built to handle thousands of kilometres on regional roads.
How Your Mobile Office Gets Built
Consultation
We discuss your mobility requirements, how often you relocate, road conditions, crew size, and whether you need integrated amenities.
Chassis & Layout Design
We engineer the trailer chassis for your specific use case and configure the internal layout from our standardised options.
Factory Manufacturing
Your mobile unit is built in our controlled facility. Chassis, structure, interior, and electrical are all assembled and tested before it leaves.
Road Registration & Compliance
We handle all road registration, compliance certification, and transport documentation so your unit is legally ready to tow from day one.
Delivery to Site
We deliver your mobile office to your first worksite. You hitch it up and go, from that point on, it moves when you move.

Frequently Asked Questions
The Real Cost of Crane-Dependent Offices
Every time a traditional portable building moves site, you pay for crane hire ($1,000-$3,000), oversized load permits, and lost productivity during setup. A Modubuild towable unit costs $0 to relocate beyond fuel. For operations that move three or more times per year, the towable unit pays for itself within the first year.
What vehicle do I need to tow a Modubuild trailer office?
Most of our standard towable offices can be towed with a heavy-duty ute or light truck with the appropriate towing capacity. We’ll confirm the exact towing requirements during consultation based on your chosen configuration and size.
Are the trailers registered for road use?
Yes. Every Modubuild towable unit is delivered with full road registration and compliance documentation. You can legally tow it on public roads from day one.
Can I add a toilet or kitchenette to a towable unit?
Absolutely. We offer towable configurations with integrated toilet, shower, and kitchenette options. These are fully plumbed and operational, connect to site water and power and you’re self-sufficient.
Quality You Can Trust: Guaranteed
We stand behind every mobile unit we build. If it doesn’t meet the agreed specifications, we’ll make it right at our cost.
