Overview
Khun by Yoo is Thailand's first branded residence by YOO Studio, designed in collaboration with the world-renowned Philippe Starck. Completed in 2020 by Sansiri as part of their Luxury Collection, this 27-storey tower is an architectural statement inspired by Thonglor's industrial heritage. The building is instantly recognizable by its striking copper core facade, raw concrete accents, and full-height insulated glass that reflects the district's vibrant energy.
The project is famous for its "Industrial Heritage" design philosophy, where opulent luxury meets raw, creative expression. With only 148 units, it offers an incredibly exclusive living experience. Residents enjoy bespoke amenities such as a swimming pool that mimics a starry night sky via fiber-optic lighting and a resident lounge serving complimentary nitro coffee. In 2026, it remains one of the most prestigious "Trophy Assets" in Bangkok, often frequented by Thai high society and design-conscious expatriates.

The building is managed with meticulous care, featuring a common area fee (CAM) of 130 THB/sqm, which covers the elite concierge staff and the maintenance of its high-spec automated parking system.
