One of the first questions clients ask when they begin planning a new home or renovation is:
“How long will this take?”
The truth is every project is different. The timeline for an architectural project depends on its scope, size, location, and level of customization. But having a general understanding of each design and construction phase helps set realistic expectations.
At Lilly Architects, we’ve guided Tulsa homeowners through this process from initial sketches to the day they move in. Here’s a clear breakdown of how long a typical home architectural project takes and what happens at each stage.
1. Pre-Design and Discovery (2–4 Weeks)
Before any drawings are made, your architect will start by understanding your vision.
During this stage, you’ll:
- Meet for an initial consultation
- Define goals, budget, and priorities
- Discuss style preferences and functionality
- Conduct site visits or feasibility studies
This is also when Lilly Architects gathers existing documents, zoning details, and site information. It’s a crucial step to ensure the design fits your site and complies with Tulsa’s local codes.
Estimated Time: 2–4 weeks
Tip: Being prepared with your wish list, budget, and any reference images can shorten this phase.
2. Schematic Design (4–8 Weeks)
This is where the creative process begins.
Your architect will explore multiple design concepts, refining spatial layouts, forms, and materials. You’ll receive:
- Sketches and 3D visualizations
- Preliminary floor plans and elevations
- Early cost and feasibility discussions
The goal is to align design vision with functionality, lifestyle, and budget before diving into technical work.
Estimated Time: 1–2 months
Variable Factors: Decision-making speed and number of design revisions.
At Lilly Architects, we ensure clients are involved through interactive design meetings so there are no surprises later.
3. Design Development (6–10 Weeks)
Once a concept is approved, it’s time to refine it into a fully coordinated design.
This phase includes:
- Finalized layouts, materials, and finishes
- Integration of structural, mechanical, and lighting systems
- Detailed exterior and interior design documentation
Your architect may also collaborate with engineers, landscape designers, and consultants during this period.
Estimated Time: 1.5–2.5 months
Tip: Prompt feedback from clients helps keep this phase on schedule.
4. Construction Documentation (8–12 Weeks)
Here, the design becomes technical. Architects create comprehensive construction drawings used for permits and building.
Documentation includes:
- Detailed floor plans, sections, and elevations
- Code compliance documentation
- Material and finish specifications
- Coordination with consultants and engineers
This phase requires precision and accuracy small errors can cause major delays later.
Estimated Time: 2–3 months
Outcome: A complete set of permit-ready construction documents.
5. Permitting and Approvals (4–8 Weeks)
In Tulsa and most Oklahoma municipalities, architectural drawings must be reviewed and approved before construction begins.
During this stage, your architect helps you:
- Submit plans to the local building department
- Respond to any review comments
- Revise and resubmit if necessary
Depending on local workload, permits can take from 4 to 8 weeks (sometimes longer for complex or historic properties).
Estimated Time: 1–2 months
Tip: Partnering with a local architect familiar with city codes like Lilly Architects can significantly streamline approvals.
6. Contractor Bidding and Selection (3–6 Weeks)
Once permits are in process or approved, your architect assists with contractor selection.
This phase includes:
- Issuing drawings to qualified contractors
- Reviewing bids and proposals
- Negotiating pricing and construction terms
If you already have a preferred builder, this step may move faster.
Estimated Time: 3–6 weeks
Variable Factors: Contractor availability and project size.
7. Construction Phase (6–18 Months)
Construction is typically the longest phase of the entire process and its duration depends on the project’s complexity and size.
Project Type - Typical Duration
Small Renovation - 3–6 months
Medium Custom Home - 9–12 months
Large or Complex Home - 12–18 months+
During construction, your architect’s role includes:
- Site visits and progress reviews
- Coordination with contractors and consultants
- Addressing design adjustments or unforeseen issues
At Lilly Architects, we stay involved from start to finish ensuring every design decision is executed with precision and integrity.
8. Project Completion and Move-In (2–4 Weeks)
As construction wraps up, your architect and contractor will:
- Create a punch list of remaining details
- Verify all systems and finishes meet design intent
- Conduct a final walkthrough before handover
You’ll also receive record drawings, warranty documents, and maintenance guidance.
This marks the exciting moment when your home officially becomes yours.
Estimated Time: 2–4 weeks
9. Summary Timeline: From Start to Finish
Phase - Average Duration
Pre-Design - 2–4 weeks
Concept Design - 4–8 weeks
Design Development - 6–10 weeks
Construction Documents - 8–12 weeks
Permitting - 4–8 weeks
Bidding/Negotiation - 3–6 weeks
Construction - 6–18 months
Move-In - 2–4 weeks
👉 Total Duration: Typically 12–24 months from start to finish, depending on scope and complexity.
10. Factors That Influence Your Project Timeline
Several factors can extend or shorten your timeline:
- Scope: A single-story home vs. a multi-level custom home.
- Decision-making: Frequent design changes delay progress.
- Permits: Historic zones or special approvals may take longer.
- Budget and material availability: Supply chain delays can impact construction.
- Contractor workload: Availability of skilled labor is key.
At Lilly Architects, we work proactively to manage these variables keeping communication open and expectations realistic at every step.
