IE House is a transformation project in which an existing building constructed in the 1990s has been reinterpreted to meet contemporary living requirements and current standards of architectural quality. The potential offered by the existing façade has been retained while being integrated with a modern aesthetic; within the limits permitted by the original structure, the façade was simplified and clarified, translating it into a contemporary architectural language. Interior spaces were reconfigured by eliminating the insufficient solutions of the original layout and replacing them with more functional and comfortable environments that respond to present-day user needs. The most significant transformation occurs on the first floor, where the former arrangement of three bedrooms and one bathroom evolved into a new layout consisting of three bedrooms, three bathrooms, and an additional workspace. This reorganization not only increases functional capacity but also significantly enhances spatial quality and programmatic richness. Throughout the transformation process, a carefully balanced relationship was established between the building’s existing structural identity and the new interventions. A modern interior organization—supported by openings that increase natural light penetration and a restrained, minimal material palette—both preserves traces of the past and responds to contemporary patterns of living. IE House stands as an architectural renovation that prioritizes adaptation over demolition, transforming an existing structure into a functional, livable home aligned with present-day standards.
