Prefab Buildings & Insulated Modular Homes in India
Wedge Industries Limited designs, manufactures and installs prefab buildings on a galvanised steel frame with MgO and cement-board walls and an R10 insulated core — homes, A-frame cottages, site offices, labour housing, mini cold storage and agri warehouses. From ₹4.75 lakh, shell up in under a month, 30+ year service life.

What are prefab buildings?
Prefab buildings are structures whose frame and wall panels are made in a factory to exact size, then transported and assembled on site in days instead of months. Wedge prefab buildings use a light-gauge steel frame (LGSF) or steel-hybrid frame, clad outside in UV-coated cement board and waterproof MgO board, with high-density stone wool or PUF insulation inside. The result is a building that is lighter, faster, better insulated and more earthquake-resistant than brick and block, and that can be expanded or even relocated later.
India’s Building Materials & Technology Promotion Council promotes light-gauge steel and panel systems as emerging construction technologies for affordable housing — the same systems Wedge uses for homes, cabins and cold storage.

Prefab buildings vs conventional masonry
| Aspect | Conventional masonry | Wedge prefab buildings |
|---|---|---|
| Construction time | Several months to over a year | Weeks — under 1 month for the shell |
| Energy efficiency | Needs added insulation | Insulation built in (R10 envelope) |
| Wall thickness | 230–350 mm external walls | 120–150 mm Wedge panels |
| Wall weight | 400–500 kg/m² | ~90 kg/m² |
| Seismic performance | Brittle | Ductile steel frame |
| Maintenance | Regular upkeep | Much lower — stable modern materials |
| Relocation / expansion | Not possible | Modular — expand or re-site |
The Wedge prefab wall system

| Layer (outside to inside) | Material | Thickness |
|---|---|---|
| Cladding | UV-coated high-strength cement board | 8 mm |
| External board | Waterproof perlite-magnesia MgO board | 12 mm |
| Frame + insulation | Galvanised steel C-sections + R10 high-density stone wool | 90 mm |
| Internal board | MgO board, finish-ready | 10 mm |
| Total | Complete insulated wall | 120 mm |
R10 insulation · 48–55 dB acoustic rating · non-combustible boards · waterproof, mould-resistant envelope. For faster builds, walls can also use cement-faced PUF sandwich panels (74 mm panel, core R 2.27 m²K/W). Need fire-rated rooms? Add fire protection doors and boards.
Mini cold storage and rural agri warehouses
Compact, modular prefab buildings for farms, FPOs, dairies, horticulture clusters and rural markets — bringing the cold chain to the farm gate and cutting post-harvest losses. See the mini cold storage price guide.
| Feature | Mini cold storage specification |
|---|---|
| Envelope | Insulated PUF sandwich panels, vapour-barrier sealed |
| Temperature | Chilled 2–8 °C (potatoes 4–6 °C) to frozen sub-zero |
| Humidity | ~85–90% RH to prevent sprouting and rotting |
| Refrigeration | Inverter compressors, load-sharing with backup |
| Power | Grid, generator or solar-ready off-grid |
| Configuration | Fixed on site or mobile on wheels |
Rural agri warehouses: steel portal / PEB frame with insulated roof and wall panels, ventilation and moisture control, wide clear spans for stacking, and modular bays that extend as storage grows — for FPOs, mandis, cooperatives, agri-input dealers and PACS schemes.

Prefab buildings FAQs
How much does a prefab building cost in India?
Wedge prefab buildings start from ₹4.75 lakh for a 300 sq ft readymade steel house. A 1 BHK (430 sq ft) costs ₹10.5–24 lakh, a 2 BHK (700 sq ft) ₹19.5–41 lakh and a 3 BHK (1,050 sq ft) ₹29–62 lakh, excluding GST, foundation and transport.
How long does a prefab building take?
Factory production takes 30–45 days and installation 3–30 days depending on size, so most prefab buildings are delivered in 4–6 weeks from design freeze. The shell goes up in under one month, versus 8–12 months for masonry.
Are prefab buildings durable and safe?
Yes. Wedge prefab buildings use a galvanised light-gauge steel frame clad in MgO and cement board, engineered for a 30+ year service life. They are non-combustible, resist rot, termites and corrosion, and flex safely under seismic load.
Are prefab buildings well insulated?
Yes. The standard 120 mm wall has an R10 high-density stone wool core and a 48–55 dB acoustic rating, so rooms stay cooler in summer and warmer in winter with lower air-conditioning cost.
Can prefab buildings be relocated or expanded?
Yes. Modular buildings can be extended in bays, and the Building-on-Wheels range — tiny homes, cottages, shops, mini cold storage and warehouses — is built on a trailer chassis so it can be moved.
Do you deliver prefab buildings outside India?
Yes. Wedge Industries Limited has manufacturing bases in India, UK, Spain and China and exports to 45+ countries, including the Gulf, UK, USA and Australia.
