Product overview

The BST X-fold container house is built around an engineered X-type linkage support structure that stays mechanically balanced both closed for transport and fully opened on site. It rewrites the industry norm for folding buildings — no wobble, no fatigued joints — by pairing smooth high-frequency folding with long-term static stability, and every unit ships as a module with complete living functions already installed. Folded, it stays highly compact, so more units stack into each sea container and road trailer, cutting cross-border and local freight costs.

01Core structure & materials

X-type linkage structure

An engineering-grade X-shaped linkage spreads loads evenly across the frame, keeping the unit rigid and stable in both transport and deployed states.

High deformation resistance

Wind loads and lateral stress are dispersed effectively, raising the whole building’s compression, seismic and structural durability.

A new folding standard

It overcomes the classic folding-house pain points of sway and joint fatigue, combining smooth repeated folding with dependable long-term stability.

02Core advantages

01

Unfold and use

Each module is designed and pre-fitted as an independent space unit — it leaves the factory complete and ready to operate.

02

Almost no groundworks

Very low demands on site flatness and foundations let it settle on mountains, sand, temporary sites and other difficult terrain.

03

Deploy on demand

No second construction phase: machine or manual unfolding puts the unit into service within hours for humanitarian relief, mining camps, mobile offices, brand roadshows and showrooms.

Frequently Asked Questions

What is the difference between X-type and Z-type folding container houses?

They differ in folding structure, on-site unfolding procedure and loading quantity. Standard outside dimensions are 5.8 × 2.46 × 2.43 m and 5.8 × 2.48 × 2.48 m, with 14 and 10 sets per 40HQ respectively. The X-type needs temporary support rods to raise the front and rear end panels; the Z-type needs two long side walls fitted and corner drainage completed.

Can X-type or Z-type folding houses be customised in size?

Non-standard sizes can be considered, but the standard sizes are designed around the folding mechanism and 40HQ transport. Changing the size affects the frame, hinges, folding hardware, panel lengths, door and window positions, lifting method and folded transport dimensions, and may require a 40 ft open-top container. Where more space is needed, joining standard modules is usually more practical than enlarging a single unit.

What is included as standard on the X-type and Z-type?

The two types differ. X-type: galvanised folding steel frame with flat roof, 15 mm cement-based floor, 50 mm EPS wall panels, steel security door, single-glazed uPVC sliding windows and two LED lights. Z-type: hot-dip galvanised frame, 50 mm EPS roof panel, 18 mm cement board with 2.0 mm PVC flooring, 50 mm EPS wall panels, steel door and two sliding windows.

Can fittings and finishes be customised — bathroom, kitchen, doors and windows, colours?

Yes. Bathroom and kitchen options include an integrated bathroom, a partitioned bathroom, a simple kitchen and a premium kitchen. Windows come in uPVC, aluminium alloy or thermal-break aluminium, and doors in steel, roller shutter, double-leaf, aluminium alloy and more. The standard is one door and two windows with positions and quantities customisable. White is the standard exterior with grey and wood-grain available, and the Z-type can take a glass curtain wall on both the short and the long sides.

How are folding houses transported, and can they be folded and moved to another site?

They ship folded into compact units and are secured inside the container — about 14 X-type or 10 Z-type units per 40HQ — with loose parts and accessories packed separately; the destination port needs container handling and transfer equipment, and non-standard sizes may need an open-top container. Yes, they can also be folded and relocated: disconnect water and power, empty or secure furniture and equipment, check the frame, folding hardware, bolts, seals, panels, doors and windows, remove site trims that block closing, and always use the designated lifting points.

What site preparation and on-site work does unfolding require?

Both types need lifting equipment and a level working surface. X-type: lift the unit, stabilise it with support rods, fold up the front and rear end panels and fix the corner posts. Z-type: lift the unit, fix the four corner posts, fit the two long side walls and finish the corners and edges. Prepare level support points, truck and crane access, room to operate the end panels and support rods (X-type) or the two side walls (Z-type), clear obstacles above the lifting area, and reserve water and power connections according to the drawings. Once the frame is fixed, connect services and check doors, windows and systems. Nobody may stand inside the lifting area while the unit is being lifted.

Can folding houses be joined or stacked?

Yes, they can be joined and a two-storey option is available. The foundation, unit and floor connections, stair landings and railings, roof and joint waterproofing, and services must be designed as a whole. Never remove frame members or cut large openings on site without a design. Confirm the full layout, number of storeys, use and site conditions before production, and obtain local approvals.

How do X-type and Z-type folding houses perform in wind and earthquakes?

Wind resistance is typhoon category 12 (wind speed 32.7–41.4 m/s) and seismic resistance reaches intensity 8.
