PREMIUM EXPANDER
At Instant Flat, we have elevated the concept of mobile living with our flagship Premium Expander series, available in 20ft, 30ft, and 40ft configurations. Unlike standard portable units, the Premium Expander is defined by an impressive 2.4-meter ceiling height that immediately transforms the interior atmosphere. This added vertical space provides a significantly more open and airy feel, ensuring that your home feels like a true sanctuary rather than a compact unit. This sense of openness is further enhanced by a sophisticated dual-roof design; while maintaining the core 50mm flat roof and ceiling system, we have added a secondary pitched roof. This architectural upgrade not only lends the home a classic aesthetic but also delivers superior thermal insulation and enhanced rainwater drainage, providing a quieter and more comfortable living environment regardless of the weather.
The transition between indoor and outdoor living is seamless thanks to the inclusion of a stunning undercover verandah. This outdoor extension is the perfect setting for a weekend BBQ, an alfresco dining experience, or simply a quiet space to admire the surrounding scenery, making it the ultimate lifestyle choice for those who refuse to compromise on style. Inside, the 20ft model is thoughtfully laid out to include two generous bedrooms and a versatile living area that adapts to your unique needs. The heart of the home is a well-appointed kitchenette featuring a complete set of overhead and base cabinetry with ample drawer storage, all pre-configured for easy connection to a gas stove and refrigerator.
Luxury extends into the bathroom, which boasts a full-width shower area equipped with twin shower heads, a modern toilet, and a vanity complemented by a full-length mirror cabinet for a practical yet high-end finish. To ensure year-round comfort, the entire is built using a high-performance EPS sandwich panel system for both internal and external walls, providing exceptional energy efficiency. The home comes pre-fitted with double GPOs to make air conditioning installation effortless. With a wide range of external cladding selections available, you have the creative freedom to personalize your home’s exterior to suit your unique taste. Experience the perfect blend of functionality and elegance with the Instant Flat Premium Expander.
