Engineered offsite building systems
Prefab Buildings Shaped Around the Project Brief
Plan commercial, institutional, and site buildings around real occupancy, performance, logistics, and delivery requirements.

What we build
Five Building Categories
Each category answers a different question about site, permanence, and scale. Start from the one closest to your project and narrow down from there.

Prefab Structures
Prefab structure solutions for site facilities, offices, social amenities, and institutional needs.
Containers
Portable modular systems planned for efficient transport and site assembly.
11 solutionsSteel Homes
Contemporary home concepts developed around steel-frame systems.
4 solutionsPrefab Homes
Comfortable prefab home concepts designed for coordinated assembly.
5 solutionsCabins
Compact cabin solutions for security, reception, and special-purpose use.
8 solutionsA closer look
From Category to Building
A hotel block, a permanent house, a stacked site headquarters, a villa, and a school. The same planning discipline sits behind all of them.
Where projects usually start
Frequently Planned Solutions
A cross-section of the 38 solutions we document, covering site facilities, workplaces, housing, and security positions.
Prefab Structures
Prefab Site Buildings
Offices, accommodation, dining, and welfare planned as one construction camp rather than as separate units.
ContainersOffice & Site Containers
Units that combine and stack from a single supervisor cabin into a multi-storey project headquarters.
ContainersContainer Homes
Complete dwellings delivered ready to place, level, and connect, from studio to two-bedroom layouts.
Steel HomesSingle-Storey Steel Homes
Permanent light gauge steel houses on one level, engineered for the seismic conditions at the site.
Prefab HomesAffordable Mass Housing
Housing programmes where repetition delivers the economy and separation standards hold across every dwelling.
CabinsArmored Security Booths
Protected positions with a stated classification for walls, roof, and glazing rather than a description.
Where the work goes
Sectors We Plan For
Each sector brings its own regulations, occupancy rules, and performance expectations, and those shape the building long before the finishes are chosen.
- Construction and infrastructure
- Mining and energy
- Education
- Healthcare
- Hospitality and tourism
- Industry and logistics
- Public and municipal
- Residential development
Why Stronx
Planned Before It Is Priced
Offsite production shortens the programme. It does not remove the planning, engineering, approvals, and commissioning a building still needs.
01
A scope you can compare
Every proposal states what is included and what is not, so two quotations answer the same question instead of hiding the difference in exclusions.
02
Engineered for your site
Structure, foundations, and anchorage are designed for the wind and seismic actions where the building actually stands, not for a generic case.
03
One point of responsibility
Design, production, transport, installation, and commissioning are coordinated by one team, with the site boundary written down before the order.
Choosing between systems
Which One Fits Your Project?
The honest answer usually comes from three questions: how permanent the building is, how soon it has to work, and whether it will ever move.

Before you order
What Buyers Ask First
The questions that decide whether a proposal is comparable, and whether the programme is realistic.
How quickly can a building be ready?
The figures in the comparison table describe how long placing and connecting the building takes once it has been produced. The full programme also covers design approval, the production slot, site preparation, and the approvals that apply at the location. We give both dates in a proposal so the difference is visible before an order.
What does a quotation include, and what sits outside it?
Every proposal names the scope explicitly: the building, its envelope and internal layers, the services included, transport, installation, and commissioning. It also names what belongs to the site, typically foundations, utility connections up to an agreed point, access, and permits. Two quotations can only be compared when both answer the same question.
What has to be ready on site before delivery?
A level, load-bearing base built to the stated foundation basis, access for the delivery vehicle and lifting equipment, and utilities brought to the agreed positions. We confirm the ground conditions, anchorage requirement, and crane positions during design rather than on delivery day, because a unit that cannot reach its position is a programme problem, not a product problem.
Are these permanent buildings?
It depends on the system. Steel homes and prefab homes are designed as permanent buildings. Prefab structures can be either, depending on the brief. Containers and cabins are usually relocatable, and stay relocatable only if the foundation, connections, and anchorage are planned that way from the start.
Can the layout be changed?
Within the limits of the system. Modular and panel systems have fixed dimensional modules, so moving a partition, adding a door, or enlarging an opening may fall on a joint and affect structure, insulation continuity, or a tested fire assembly. We record which dimensions are fixed and which changes need engineering review before manufacture.
Who handles permits and approvals?
Requirements vary by location and by intended use, so we name the responsible party for each approval in writing before an order instead of assuming it. We provide the structural design basis, the fire strategy for the intended occupancy, and the as-built information and certificates the authority or the operator will ask for.
