ATP Development & Construction provides coordinated architectural and engineering design services for homeowners, investors, and developers throughout Los Angeles.
Our design phase focuses on feasibility, code compliance, structural integrity, and long-term buildability — ensuring your project is properly planned before construction begins.
By aligning design with real-world construction experience, we reduce delays, minimize costly revisions, and create a clear path from concept to approved plans.
Architectural Planning
We develop permit-ready architectural plans aligned with structural requirements and city regulations.
Includes:
• Site analysis & feasibility review
• Floor plans & elevations
• Zoning & setback verification
• Construction-ready documentation
Engineering & Compliance
We develop permit-ready architectural plans aligned with structural requirements and city regulations.
We coordinate:
• Structural engineering
• Soils & hillside reports
• City plan check responses
• Permit submission & approval
Designed With Construction in Mind
Our design team works alongside construction from day one to reduce revisions, delays, and cost surprises.
This means:
• Realistic budgets
• Structural feasibility considered early
• Fewer plan revisions
• Smoother transition into build phase

Frequently asked questions
Do I need my own architect?
No. ATP provides coordinated architectural and engineering services in-house. You work with one team from concept through permit approval.
How long does the design phase take?
Most residential design phases take approximately 6–10 weeks depending on complexity, revisions, and city requirements. Permitting timelines vary by jurisdiction.
Can ATP handle permitting?
Yes. We manage full plan submission, zoning review, and plan-check corrections with Planning and Building & Safety until approval.
Can I make changes after plans are submitted?
Minor adjustments are often possible, but significant changes after submission may require resubmittal and could extend timelines. We guide you through options before proceeding.
What documents do I need to begin design?
Typically:
- Property address
- Proof of ownership
- Any existing plans (if available)
- Insurance documentation (for fire rebuilds)
We review everything during consultation and outline next steps clearly.
