The F40 model represents a balcony-enclosed iteration of the T40 prototype. Maintaining the core layout blueprint of the T40 series, this configuration expands usable floor area through integrated balcony encapsulation.

The original balcony space now accommodates customizable wet area or lounge installations (bathtub/sofa options), complemented by modular soft furnishings that permit flexible DIY combinations. This engineered adaptability enables multifunctional spatial programming for diverse residential applications.
