Design Services
Design that’s made
to be built.
Architecture, engineering, and interiors under one roof — aligned with real-world construction from the very first sketch.
The ATP Difference
Plans coordinated with construction — not handed off and hoped for.
Most projects break down in the gap between design and construction. We close that gap by keeping architecture, engineering, and the build under one accountable team.
The result is permit-ready documentation, fewer redesigns, and a smoother path from concept to approval to completion. And because our services aren’t locked together, you’re always free to review your plans and compare builders before deciding who builds.
Design Disciplines
Everything your project
needs to get approved.
Architecture Plans
Permit-ready architectural design coordinated with the build from day one.
Explore →Structural Engineering
Safe, efficient, code-compliant structural design and calculations.
Explore →Civil Engineering
Grading, drainage, and site development for complex California lots.
Explore →Interior Design
Finishes, fixtures, and flow, specified and built to match the vision.
Explore →How Design Works
From concept to permit set.
Concept & Feasibility
We review your site, goals, and budget, then explore design directions that are both inspiring and buildable.
Design Development
Architecture, structural, and civil are coordinated together so the design holds up technically and financially.
Construction Documents
We produce detailed, permit-ready drawings and specifications ready for plan-check and construction.
Permitting & Approvals
We manage city submittals and plan-check revisions, keeping your project moving toward approval.
Let’s design it right.
Bring us your site and your vision — we’ll turn it into a permit-ready plan with construction already in mind.
