Penthouse Renovation, Residential Architecture & Interior Design – Istanbul A complete penthouse renovation and interior design project developed for a private residence in Istanbul. The project involved the renovation and transformation of an existing two-level penthouse, with a focus on improving functionality, spatial quality, aesthetics, and the relationship between indoor and outdoor living areas while respecting the existing architectural geometry and structural limitations. The design concept combines Japandi, contemporary minimalism, and Wabi-Sabi principles, using warm neutral tones, natural materials, textured surfaces, and carefully integrated lighting to create a calm and sophisticated residential atmosphere.
