Looking for a ready-to-live prefab house? Our 20ft sloped-roof unit with private terrace will be a great choice. It has two bedrooms plus one living room, and adopts double expandable side wings together with a stretch covered terrace. This design saves lots of shipping space and brings you extra outdoor area to relax.
When folded, its width is only 2.2 meters. We can put two full units into one 40HQ shipping container, which helps you cut down overseas transport fees a lot. Almost all parts are finished in our workshop, including galvanized steel frames, sturdy sloped roof frames, complete kitchen and bathroom sets, as well as all internal wiring.
This house works well for holiday cabins, rural houses, glamping accommodation and long-term family housing in different countries.
Features
Product Description
Unlike standard flat-roof container homes or basic terrace-only models, this 20ft prefab house combines two core advantages: a sturdy gable sloped roof for superior rainwater drainage and a classic home look, plus a foldable covered terrace that adds 5.76 sq.m. of outdoor space without extra land take. Its double-side wings expand on-site to create a full 37 sq.m. of indoor living space, while the terrace folds flat against the main wall for compact shipping.
All structural frames, wall panels, door and window frames, plus full kitchen and bathroom fittings are pre-installed before shipment. No on-site cutting, welding or complicated finishing work is required. The whole structure passes windproof, rainproof and seismic testing, and only needs flat concrete or compact gravel ground to be placed-ready for immediate use after a simple 3-step assembly process.

All bearing beams, columns and terrace support brackets adopt hot-dip galvanized steel to stop rust, even if placed near the sea or humid areas.

Standard galvanized lifting lugs (L210×W150×H160mm) make loading and unloading by crane easy. The whole frame is sprayed and baked, with stable performance for 15 years and above under normal outdoor use.

All bolt holes, door and window frames are pre-made in the workshop. Wires and water pipes come with flexible connecting ends for quick hook-up. Terrace guardrails are already mounted, no extra assembly work. Two workers with basic hand tools can finish placing, leveling and fixing the whole house within 2 hours.

Customer Cases

How are they transported and installed?
Our 20ft Terrace and Sloped Roof Prefab House is fully pre-assembled in the factory before shipment. The folded slim unit is loaded into 40HQ high cube containers for sea transport, with all frames, wall panels, doors, windows, kitchen and bathroom fixtures, plus terrace components included in one complete set.
Before unloading, level the construction ground completely; sloped or muddy ground needs concrete leveling work in advance. After lifting the folded unit down with a crane or forklift, workers unfold the two side wings, lock the frame in place, and connect the external power and water supplies. The whole house installation takes only 3–4 hours for 2–3 workers, and the terrace can be set up in an extra 15 minutes. No complex professional construction is required, making this turnkey design perfect for fast deployment of family homes, glamping resorts, emergency housing and other residential projects.
