Understanding the 6 Phases of Architectural Design: From Concept to Construction
Mariana Mejia
When starting any building project residential, commercial, or mixed-use understanding the architectural design phases is essential. These stages guide the transformation of a simple idea into a fully constructed space. Here's a breakdown of the 6 essential phases of the architectural design process, and why each one matters.
Phase 1: Pre-Design & Programming
Before drawing anything, the architect conducts research and analysis. This phase includes:
Understanding the client’s goals and lifestyle
Site analysis: sunlight, access, zoning restrictions
Budget and timeline assessment
Phase 2: Schematic Design (SD)
This is the conceptual phase. Architects create rough sketches and spatial diagrams to:
Define volume and flow
Propose initial materials and massing
Visualize the building’s relationship to its environment

Phase 3: Design Development (DD)
The concept becomes more real. Architects:
Choose materials and finishes
Develop structural, mechanical, electrical strategies
Refine space dimensions and façade treatments
Phase 4: Construction Documents (CD)
This is the most technical phase. Architects produce:
Detailed plans, sections, elevations
Technical specifications and annotations
Structural and MEP coordination
These documents are used for contract bidding and construction.

Phase 5: Bidding & Permitting
Architects help:
Prepare and submit building permits
Select qualified contractors through a bidding process
Answer technical questions during contractor evaluation
Phase 6: Construction Administration (CA)
The architect visits the site to:
Ensure the design is built as planned
Review shop drawings and materials
Approve payments and change orders if necessary
Phase | Key Activities | Outcome |
|---|---|---|
Pre-Design | Site research, user needs, code review | Project brief and scope defined |
Schematic Design | Concept sketches, basic layout | Preliminary spatial organization |
Design Development | Refined layout, structure, materials | Coordinated design ready for documentation |
Construction Documents | Drawings, specs, technical detailing | Ready for permits and contractor bidding |
Bidding & Permitting | Permit submission, contractor selection | Legal and team setup complete |
Construction Administration | Site visits, change review, payment approval | Final construction aligned with design |
