Casa móvel pré-fabricada expansível de 20 pés com duas asas
Inside the 20ft shell: a living and dining room at 4.7 × 3.6 m with a 2230 mm ceiling, a bedroom that leaves 700 mm walkways around a double bed, a 1.6 × 2.1 m bathroom and a 2.4 m kitchen run. Five 960 mm sliders and an 897 mm steel door. The fit-out arrives installed, so the first night on site is an ordinary night.

Travelling closed, the 20ft expandable double wing prefab mobile home opens into a room wider than the trailer that brought it. Floor area comes to 37.2 m² under a 2230 mm ceiling, with the roof line at 2,480 mm. Both wings push out along the long sides. Weight with the fittings is 3,200 kg, so a light crane or a heavy forklift takes it at the pad. Closed, it still fits a standard trailer.

Square Tube Frame and the Insulated Deck
The chassis is welded from 2.5 mm galvanized square tube. Wing frames are cut from 1.5 mm tube on the same line. Each corner post is a folded 1.8 mm section, tied into a 4 mm lifting plate at the corner of the chassis. A 130 mm hinge runs full height. Paint goes on before the panels close, and galvanized steel holds up in damp air without repainting.
Parts welded into the frame · Chassis tube of 2.5 mm, hot dip galvanized · Wing frames formed from 1.5 mm tube · Corner posts in folded 1.8 mm sheet · Lifting plate, 4 mm steel · Hinge of 130 mm, running the joint height
Walls of the 20ft expandable double wing prefab mobile home take 65 mm panels. Both faces take a 0.35 mm skin, while roof and cut-off panels measure 50 mm. Partitions between rooms use the same 50 mm core. An 18 mm cement deck carries an SPC sheet from the core section out to each wing tip, and the thicker skin eases the air conditioner. Foil tape closes every joint before the unit leaves the line.
Envelope layers, outside in · Wall panel of 65 mm with 0.35 mm facing · Roof deck panels of 50 mm · 50 mm partition between bedrooms · 18 mm cement deck under SPC sheet · Foil tape along each panel joint
Sockets, Ceiling Lights and Circuit Breakers
Every 20ft expandable double wing prefab mobile home ships with cable and sockets fitted. Lamps, sockets and the cooling line each have a breaker behind the main switch. Voltage and plug type follow the local market. Two 1.5 kW splits serve the living area and the bedrooms. Water arrives on PPR pipe and leaves through PVC waste, with one drain under the floor. A leakage trip guards the socket ring, and the board carries a printed label under each switch so a worker can tell the circuits apart at a glance. Cable runs through the ceiling void and drops where a desk or a bed will stand.
Entry Door, Sliders and Wet Bathroom
The entry is a steel door with a 1970 mm leaf and a bar set on the inside face. Five sliding windows of 960 mm bring light into the living space and into both wings. Aluminium frames carry fly screens, and double glazing can be ordered. Inside, the bathroom holds a shower tray with a mixer, a WC, a vanity and a mirror cabinet. An extractor and a drain keep it dry.
Bedroom Plans and Exterior Finish Options
One or two bedrooms fit the same 37 m² plate, and a straight counter of 2.4 m suits the kitchen wall along one side. The bathroom keeps 2.1 m of length for the shower. Colour, cladding and the siting of every opening are open to choice. Interior wall panels come in EPS or polyurethane. Room count can change on the same 20ft double wing expandable house.
Opening Both Wings in One Day
Four workers open a 20ft expandable double wing prefab mobile home in one day. Each wing turns on its 130 mm hinge and locks down with cam bars at all four corners. It comes painted and framed, with cladding, joinery, cable and floor finish complete. Site work covers the pad, the wing seals and the services. Nothing is welded and no wet trade is used.
Packing Film, Shipping and Common Uses
Each unit is wrapped in plastic film, then in a rainproof cloth, before loading. Two folded units fill one 40HQ bay at 50 mm walls. Long road legs by truck are normal, and the closed box lifts at either end. A 20ft expandable double wing prefab mobile home of this size suits staff quarters, site offices, rental units and small clinics. Warehouses hold stock for immediate shipment.
