This interior design project transforms two adjoining flats into a cohesive 5 BHK residence spanning approximately 1800 square feet of carpet area. The merger enhances spatial continuity, enabling improved cross ventilation and abundant natural light throughout the home. As a result, dependence on artificial cooling and lighting is significantly reduced. The design language embraces this passive environmental strategy, with interiors kept light, simple, and rooted in earthy tones. Soft textures, and uncluttered layouts create a calm, breathable atmosphere, ensuring thermal comfort while maintaining aesthetic warmth, functionality, and a strong connection to the surrounding environment for everyday living efficiency.
