Its expandable structural system allows the side sections to unfold after delivery, transforming a compact transport unit into a spacious modular building. Compared with smaller portable cabins, the 30ft model offers greater flexibility for bedrooms, living areas, offices, kitchens, bathrooms and other functional spaces.

The modern sloped-roof appearance, steel structural frame and customizable exterior finishes make this model suitable for residential developments, construction accommodation, tourism projects, offices and temporary commercial facilities.

Modern Expandable Structural Design

The house uses a central steel structural module combined with expandable side sections. During transportation, the expandable sections are folded toward the main structure to reduce shipping volume. After arriving at the site, the building can be expanded and prepared for final installation.

This design combines the transportation advantages of modular construction with a larger finished interior area.

Key Product Features

The 30ft model provides a larger floor area than compact expandable units and can accommodate more complex internal layouts. A fabricated steel frame forms the main load-supporting system, while insulated wall and roof panels create the building envelope.

Large windows and glazed entrance doors can be incorporated to increase natural lighting and create a more modern architectural appearance. Exterior finishes can include clean white panels, dark gray finishes, wood-grain decorative panels or other project-specific options.

Different insulation systems, flooring materials, doors, windows, sanitary facilities and electrical configurations can also be selected according to the destination market.

Typical Specifications

Spacious Interior Layout

One of the main advantages of the 30ft expandable house is its larger usable space after expansion.

Depending on the project, the interior can be configured as a one-bedroom or multi-room residence, combined living and dining area, office space, worker accommodation, reception room or other customized functional layout.

For residential projects, bathrooms, kitchens, bedrooms and living spaces can be integrated into the same unit. For commercial or project applications, internal partitions can be changed to create meeting rooms, offices, reception areas or open-plan working spaces.

Exterior Appearance Options

The house can be supplied in different architectural styles.

White and gray combinations provide a clean modern appearance, while wood-grain finishes create a warmer residential or resort-style effect. Dark exterior frames can also be combined with lighter wall panels to create greater visual contrast.

Large glass doors and windows are particularly suitable for holiday accommodation, guest houses, sales offices and modern residential projects.

Insulation and Building Envelope

The building envelope can be selected according to local climate conditions and project requirements.

EPS panels provide an economical insulation option for many general applications. Rock wool can be selected where different thermal or fire-performance requirements apply, while PU-based insulation options can be considered for projects requiring improved thermal performance.

Main Applications

This model is suitable for modular residential housing, worker accommodation, site offices, guest houses, holiday cabins, resort accommodation, temporary housing, construction camps, sales offices, reception buildings, rental housing and other prefabricated building projects.

Its larger expanded space makes the 30ft model particularly suitable for applications where a compact 10ft or 20ft unit cannot provide enough internal functional area.

Residential Projects

For housing projects, the expandable layout can create a comfortable living environment with separate sleeping, living and sanitary areas.

The exterior appearance and interior finish can be upgraded according to residential design requirements, making the product suitable for small homes, backyard houses, guest accommodation and temporary residential developments.
