Prefab house

A high-quality prefab house brings permanent-style comfort to a factory-built, fast-to-install home. Every module is fabricated indoors with controlled quality, then delivered and bolted together on site, so you can move in weeks instead of months – without sacrificing durability, insulation or finish quality.

Unlike temporary portable cabins, our prefab houses are engineered as real homes. The steel frame, insulated panels, doors, windows and interiors are all produced to residential standards, and the modular layout means you can combine units side by side or stacked to create anything from a single room to a complete family house.

Prefab House Applications

Prefab houses serve a wide range of living and working needs:

• Residential Homes – modern, energy-efficient living spaces for permanent or vacation use.

• Site Offices & Worker Housing – fast, comfortable accommodation for construction projects.

• Garden & Backyard Rooms – flexible extra space for home offices, studios or guest rooms.

• Temporary & Relocatable Housing – easy to move, reinstall and expand as needs change.

• Remote & Rural Housing – quality homes delivered where conventional building is slow or costly.

• Resort & Holiday Cabins – attractive, quick-to-install accommodation for tourism.

Key Features

• Fast Installation – factory-built modules assemble on site in days, not months.

• Controlled Quality – indoor fabrication avoids weather damage and quality variation.

• Energy Efficiency – insulated walls, floors and roofs reduce heating and cooling costs.

• Durable Steel Frame – corrosion-protected steel carries the structure for a long service life.

• Expandable & Relocatable – add or move modules as your family or business grows.

Standard Specification Range

Note: final specifications are confirmed against your project drawings and local climate.

Materials & Surface Treatment

Frames use light-gauge or hot-rolled steel in Q235B/Q355B with anti-corrosion coating, protected by insulated composite wall panels. Finishes are selected for your climate:

• Rock wool or PU insulated panels for thermal comfort in hot and cold regions.

• Galvanized or pre-painted steel skins for weather resistance.

• Interior linings and flooring finished to residential standard.

Prefab House System Breakdown

Each prefab house is built as a complete, coordinated package:

• Structural Frame – steel columns, beams and floor joists carry all loads.

• Wall & Roof Panels – insulated sandwich panels seal and insulate the envelope.

• Floor System – insulated, steel-framed floors with finished flooring.

• Doors & Windows – factory-fitted, weather-sealed openings.

• Services – electrical, plumbing and HVAC provisions installed per design.

Frequently Asked Questions About Prefab Houses

Start Your Prefab House Project in Three Steps

1. Send Your Requirements – share your house size, quantity or drawings through the contact form or email; our engineers confirm the key parameters with you.

2. Review Design & Quotation – we prepare the modular design and itemized quotation; you review, adjust and confirm the order.

3. Fabrication & Delivery – production starts after confirmation; your prefab house is fabricated, inspected, packed and delivered on schedule with installation support.

Why Choose Steel for Your Prefab House

A steel-framed prefab house is a deliberate choice for speed, durability and predictable quality. Because the complete module is built indoors, there is no exposure to rain, temperature swings or site supervision gaps – every weld, panel and finish is produced under controlled conditions and inspected before it leaves the factory. That consistency is hard to match with conventional on-site construction.

Steel gives the house a long, low-maintenance service life. The frame is corrosion-protected, termite-proof and dimensionally stable, so doors stay square and walls stay straight for decades. Insulated panels cut heating and cooling costs, and because modules are engineered to standard transport sizes, the same quality home can be delivered to remote locations where building materials and skilled labor are expensive or unavailable.

From a cost and schedule perspective, modular steel construction converts months of site work into weeks of assembly. That means earlier occupancy, earlier rental income or earlier family use – and a final cost that is known up front rather than drifting with site conditions.

Typical Prefab House Configurations & Layout Options

Prefab houses combine standard modules into layouts that fit your family and site:

• Single-Module House – one self-contained unit: the fastest and most economical option.

• Side-by-Side Combination – modules joined to create wider living, kitchen and dining spaces.

• Two-Storey Stack – stacked modules for a compact footprint with more floor area.

• L-Shaped or Courtyard Layout – modules arranged around outdoor space for larger homes.

• House with Porch or Balcony – optional external structures extend living space outdoors.

Packaging, Shipping & After-Sales

We treat logistics as part of engineering, not an afterthought:

• Engineered Packing – modules and components are protected and labeled for fast site identification.

• Standard & Project Shipping – containerizable modules move by standard freight, including to remote locations.

• Installation Guidance – assembly drawings and step-by-step guidance accompany every delivery; installation teams available.

• After-Sales Support – spare parts, technical consultation and warranty terms as specified in the project contract.

• Documentation – material certificates and inspection reports provided with delivery.

Project Timeline: From Order to Handover

From enquiry to handover, every project follows a controlled process:

1. Requirement & Design – confirm layout, size and finishes; issue module drawings.

2. Fabrication – frame welding, insulation filling and finishing in our factory.

3. Quality Inspection – dimensional, coating and assembly checks.

4. Packaging & Shipping – protected modules packed for efficient freight.

5. On-Site Assembly – bolted module assembly with guidance; optional installation team.

Design & Engineering Process

Every prefab house starts with your requirements, not a template. Our engineers take your floor plan, family size or simple description and confirm the key parameters – module count, layout, finishes, insulation level and local climate conditions. That confirmation becomes the basis of the modular design, so the house is right for your family from the very beginning.

The design then moves into detailed engineering: module layout, frame sizing, panel selection, door and window positions and service routes, all produced as clear production drawings. Because design and fabrication live in the same organization, every detail is checked against our production capability – welding, insulation filling and finishing details are resolved before production begins, not discovered on site.

Finally, production begins: frames are welded, insulated and finished on our assembly lines, then inspected against the approved design. The result is a house that arrives on site as complete, protected modules, ready to be joined together exactly as designed.

Performance, Durability & Maintenance

A steel prefab house is built for comfortable, low-maintenance living over decades. Corrosion-protected frames resist weather and pests, insulated panels keep energy use low, and quality finishes stay looking good with simple care.

• Expected Service Life – engineered for long-term use with proper maintenance.

• Pest Resistance – steel frames are not affected by termites or rot.

• Energy Efficiency – insulated envelopes reduce heating and cooling costs.

• Simple Upkeep – pre-finished surfaces need minimal maintenance.

• Adaptable Home – modules can be extended or relocated as needs change.

Understanding Your Cost & Quotation

Every prefab house is quoted individually because every project is different. Your quotation is built from the parameters that actually drive cost, so you can compare options and adjust the design to fit your budget.

• Module Count & Size – the number and dimensions of living modules.

• Layout Complexity – single, combined or stacked arrangements.

• Finish Level – interior and exterior finishes from standard to premium.

• Insulation & Climate Package – panels and systems for your region.

• Doors, Windows & Services – openings, electrics, plumbing and fittings.

• Shipping & Installation Scope – freight, packing and erection services.

Send your house size, quantity and requirements, and our engineers will respond with an itemized quotation as soon as your requirements are confirmed.

Installation Services & On-Site Support

How your prefab house gets assembled is your choice, and we offer three levels of support. The most common is guidance-only: our assembly drawings and step-by-step instructions travel with the modules, and your local team joins them together under our remote support. For teams with less experience, we can provide a supervisor who leads the assembly on site and trains your workers module by module.

For clients who prefer a complete package, our installation team can manage the full assembly. Either way, the process is planned in advance: foundations are prepared to our drawings, modules are delivered in order, and each unit is leveled, bolted and sealed according to the sequence that keeps the house weathertight at every stage.

Quality and comfort are built into the process. We provide joint-sealing specifications, inspection checklists and safety guidance, and every shipment is documented so site teams can verify each module against the drawings. Whatever level of support you choose, the goal is the same: a house assembled correctly, safely and ready to live in.

• Guidance-Only – drawings, instructions and remote technical support.

• Supervision – an experienced supervisor leads and trains your crew.

• Full Installation – our team assembles the complete house.

• After-Sales – spare parts, maintenance guidance and warranty support.

Questions to Ask Before You Order

A few minutes spent confirming these points before ordering saves time and cost later. Our engineers will guide you through each one:

• Site & Foundation – is the site prepared, and what foundation does the house need?

• Climate – what insulation and heating/cooling needs apply at your location?

• Access & Transport – can delivery vehicles reach the site for module offloading?

• Services – are water, power and drainage connections available at the site?

• Schedule – what is the target move-in date?
