welcome to Your NEW space

STUDIO Gillis-Moore is a Southern California-based residential design practice built on the belief that great design begins with optimism. We specialize in transforming properties through thoughtful planning, custom home design, and clear documentation.

We bridge the gap between a client’s dream and the realities of the construction process. Our team combines advanced building design and strategy to deliver solutions that are as practical as they are beautiful. From feasibility studies and zoning analysis to permit-ready drawings, we help homeowners and developers navigate the complexities of property development in Long Beach and beyond.

Our philosophy is simple: Stability through Design. We look at the "big picture" of your neighborhood to perfect the small details of your daily life. We don’t just design structures; we build value, comfort, and long-term potential.
