This three-story renovation for the Nguyena residence in Switzerland reimagines the basement as a sophisticated, multi-functional living hub. The design integrates a modern, open-concept layout featuring a minimalist kitchen with marble accents and a seamless transition into a sleek dining and lounge area. Warm wood flooring and slatted wall partitions provide organic texture against clean, white surfaces and industrial track lighting. The project prioritizes space optimization, incorporating private office nooks and a contemporary bedroom suite, ensuring the subterranean level feels airy, bright, and perfectly balanced for both professional productivity and refined European living.
