4D Design is a California-based architecture and design-build studio creating hospitality, wellness, and residential environments engineered to entrain the human nervous system.

We combine 30 years of luxury hotel and residential practice with fractal geometry, ornament, and building biology - architecture calibrated at the level of proportion, material, and light to reduce stress physiology and restore coherence.

We have built 300 buildings across four continents. Based in Los Angeles and Joshua Tree.
