20ft Wood Grain Expandable Container House
This 20ft wood grain expandable container house upgrades the standard folding-house appearance with brown vertical fluted exterior cladding and a contrasting black steel frame. The clean wood-texture finish gives the unit a more residential look for homestays, guest cabins, backyard homes and commercial accommodation projects.
The supplied factory image shows the actual house exterior. The other images on this page are application visualizations created from the same house only; no different house models are used.

Modern Wood-Grain Fluted Exterior
The vertical Great Wall-style profile creates deeper shadow lines than a flat wall surface, helping the facade look more finished and architectural. International buyers commonly describe this appearance as wood grain exterior cladding, WPC fluted wall panels or wood-texture composite cladding. The final cladding material, color and installation detail can be confirmed according to the project specification.
