Completed in 2008, I-Condominium (Home Boutique) by architect and developer Mario Kleff represents a landmark in both design and property law innovation in Thailand. Situated in Pattaya, the project is recognized as the first officially permitted housing development to enable foreign ownership of a house in an individual’s name, rather than through a company—a feat previously thought impossible under Thai law.

At the time, Thai regulations allowed foreigners to own only up to 49% of the total floor area in condominium developments, while detached houses remained restricted to Thai nationals. Mario Kleff conceived a creative architectural and legal strategy: two structurally independent buildings were designed and linked underground as one condominium project. One building represented 51% Thai ownership and the other 49% foreign ownership, perfectly aligning with legal ownership ratios.

This configuration enabled a foreign buyer to own a single, fully private home within the condominium’s framework—establishing I-Condominium as a pioneering example of how architectural design can resolve complex ownership regulations through innovation and precision.

Architectural Concept
Visually, I-Condominium stands as a bold expression of contemporary minimalism and engineering ingenuity. The cantilevered H-beam structure allows for open interior spaces and a clean, geometric silhouette. The green glass façade enhances privacy while reflecting the tropical landscape, emphasizing lightness and transparency.

Instead of external balconies, Kleff designed full-height operable windows that open entirely, allowing residents to use interior space as an indoor balcony. This maintains the purity of the façade, avoiding visual clutter while offering natural ventilation and connection to the exterior environment.

The absence of visible load-bearing walls on the glass frontage creates an unobstructed, floating aesthetic—a hallmark of Kleff’s architectural language that merges engineering mastery with modernist restraint.
