about
BEGINNINGS AND PASSION
The story of MMK Studios began in 2024, when a student of fine arts and mathematics submitted one of his designs to the A’ Design Award as a personal challenge. The project was awarded, and he was subsequently recognized as best Young Design Pioneer of the Year across all categories, marking the unofficial starting point of the studio. The founder is driven by a clear vision to create objects that captivate through exceptional craftsmanship, sculptural presence and an unconventional design language. His background in fine arts, mathematics and a fascination to technology and innovative manufacturing became the foundation of the studio.
GROTH AND VALUES
The growth of MMK Studios is intentional and measured. The studio undertakes only a limited number of projects each year to ensure full creative involvement and uncompromising quality. Integrity, discretion, and respect for craftsmanship and clients define every collaboration.
