SUMUM is a Belgian architectural hardware brand founded by designer Wesley Demeester, known for solid brass switches, outlets and lighting with a calm, timeless character. Crafted with precision and finished by hand, SUMUM pieces are designed to age beautifully and integrate seamlessly into both classic wiring and smart home systems such as KNX and QBUS.

 

At Numa Home, we curate SUMUM’s core collection and collaborations—and as the official SUMUM distributor for the Netherlands and Turkey, we help you create one coherent finish story across switches, sockets and lighting for high-end interiors and projects.
