Our Architectural Drawing Process

We begin by assessing your garage space to determine the best design path. Next, we create precise floor plans tailored to your needs. Finally, we offer 3D models to help you visualize the finished conversion.

1. Initial Consultation 

We start with a detailed consultation to understand your goals, budget, and preferences.


Our team inspects the existing garage structure, noting dimensions, utilities, and any restrictions. We assess zoning rules and local building codes in Huntington Beach to ensure compliance.


This step identifies potential challenges like load-bearing walls or permits needed. We provide clear recommendations on what’s feasible and discuss timelines to set realistic expectations.

2. Drafting Detailed Floor Plans

We translate your ideas into accurate, scalable floor plans. These include room layouts, fixture placements, and door and window locations.


Our drawings adhere strictly to California building standards. We incorporate electrical, plumbing, and HVAC details to streamline later construction phases.


Each plan undergoes multiple reviews with you for adjustments. Our goal is to create a technical document that guides builders without ambiguity.

3. 3D Visualization and Modeling

We produce realistic 3D models to help you see the converted space before construction starts.


These visualizations show spatial relationships, material finishes, and lighting effects. You can explore different design options and make informed decisions.


This step reduces surprises during building and helps ensure your vision aligns with the final structure. We use state-of-the-art software for precise, clear presentations.
