Custom homes, ADUs, additions, remodels, and pool and outdoor living plans for homeowners across Palm Springs, La Quinta, Indio, Palm Desert, Rancho Mirage, and the desert cities. Permit-ready plan sets from a design team that stays on your project until the city issues the permit.

From a 4,000 square foot custom home in La Quinta to a garage conversion ADU in Indio, every project ends with the same deliverable: a complete, coordinated plan set built around your lot, your budget, and your city's requirements. Architectural, structural, MEP, and Title 24 sheets arrive together, so plan check has less to send back.

01
Tell us what you want to build, where, and the budget you are working with. We confirm fit and the likely permit path before anything else.
02
We walk the lot or existing home and capture the details that shape the design: setbacks, orientation, utilities, and your bed, bath, and square footage goals.
03
Scope, phases, and cost in writing, typically within 24 hours of the site visit, so you know exactly what is included before you commit.
04
We set the timeline for design, engineering coordination, and submittal, then manage plan check corrections through to your issued permit.
