The residential design process typically takes 6 to 14 months before construction begins. That range covers a lot of ground. Understanding what compresses and what extends the timeline helps clients set realistic expectations before the first drawing is made.
The Design Phase Timeline Breakdown
Every residential architecture project — from a renovation to a new custom home — passes through the same sequence of phases. The time each phase takes depends on project complexity and how efficiently decisions are made.
Pre-design and site analysis (2 to 4 weeks). Site survey documentation, solar analysis, regulatory review, and program confirmation. This phase is often compressed or skipped in simpler projects but is essential for complex sites.
Schematic design (6 to 10 weeks). The architect develops 2 to 3 spatial concepts and the client selects a preferred direction. In MÉTODO, this phase includes the matriz de opciones — a structured comparison of real alternatives that prevents premature commitment to a single idea. The schematic design phase ends with a client decision. If that decision is deferred, the phase extends.
Design development (8 to 12 weeks). The selected concept is developed into a fully resolved building. Plans, sections, materials, and consultant coordination all happen here. Complexity and the number of consultants required extend this phase.
Construction documents (8 to 16 weeks). The full technical package for permitting and contractor bidding. A complex custom residence with significant custom concrete, stone, or millwork takes longer than a straightforward project with standard construction systems.
Permit review (4 to 16 weeks). The permit authority's timeline, not the architect's. In most Denver-area municipalities, residential permits take 6 to 10 weeks. Mexico City permit timelines vary by delegación and project complexity.
What Extends the Timeline
Client-side delays at phase transitions. The most common and most preventable cause of timeline extension. When a phase is complete and the client defers the required decision — selecting a schematic direction, confirming the material palette, approving the construction documents — the architect waits, and the timeline shifts.
Well-structured projects define what the client must decide at each milestone and when. The decision window is built into the schedule. A client who understands the phase structure can prepare for these moments rather than be surprised by them.
Scope changes after a phase is complete. A spatial change in schematic design costs hours. The same change in design development costs days. The same change after construction documents are substantially complete can cost weeks and affect multiple consultant drawings. The cost of a change grows exponentially with how late it occurs.
Difficult site conditions. A hillside site requiring a geotechnical report, a historic overlay district requiring design review approval, or proximity to environmental features requiring environmental assessment all add weeks of analysis before or during the design phases.
Permit jurisdiction complexity. Some municipalities have streamlined residential review processes. Others have multi-step review, design review committees, and neighbor notification requirements. An architect with specific experience in the jurisdiction can navigate this more efficiently.
What Compresses the Timeline
A clear and stable brief. A client who has thought carefully about their program, confirmed the budget, and can make decisions efficiently moves through design phases faster. The program does not need to be perfect — it needs to be sufficiently defined to start design without major revisions mid-phase.
Early consultant engagement. Bringing the structural engineer and mechanical engineer into design development — rather than waiting until construction documents — prevents the coordination revisions that add weeks.
Phased permit strategy. On projects where schedule is critical, a phased permit submission — submitting for foundation and site work before the full construction document set is complete — can allow grading or foundation construction to begin 4 to 6 weeks earlier than a standard submission strategy.
The Construction Phase Adds Another 12 to 24 Months
Design is not the end of the timeline. Construction for a custom residence typically takes 12 to 24 months from groundbreaking to certificate of occupancy. The total time from first site visit to move-in: 18 to 36 months.
This is not a reason to rush the design. It is a reason to begin the design with realistic timeline expectations so that the process unfolds without pressure to compress phases that should not be compressed.

Timeline clarity begins with a realistic assessment of project complexity, decision-making pace, and permit jurisdiction. A pre-design conversation is where those variables are established.
