Designing and building a new space—whether it’s your dream home or a large mixed-use commercial project—is an exciting, but often overwhelming journey. One of the first questions that comes up is: “How long will this take?” Architectural project timelines are not always straightforward because every project is different, but understanding the phases and timelines can help you plan ahead and manage expectations.
Let’s break it down and explore how custom homes and mixed-use projects differ when it comes to scheduling and what that means for you as a client.
Project Timelines: The Phases
Every architectural project timeline follows a series of steps. Here’s a simple overview of what happens at each stage:
1. Pre-Design
This is where your ideas take shape. Your architect will work with you to define your goals, analyze the site, and figure out zoning or permitting requirements.
Typical timeline: 2-6 weeks.
2. Schematic Design
Think of this phase as the first draft. Your architect will create initial concepts, layouts, and sketches to help you visualize the space.
Typical timeline: 4-8 weeks.
3. Design Development
Once the concept is locked in, it’s time to refine the details—materials, systems (like HVAC), and other important elements that bring your project to life.
Typical timeline: 6-12 weeks.
4. Construction Documentation
This is where the technical work happens. Your architect creates detailed blueprints and specifications for construction and permitting.
Typical timeline: 8-16 weeks.
5. Permitting
Plans are submitted for approval by local authorities. Timelines here can vary widely depending on where you’re building.
Typical timeline: 4-12 weeks.
6. Construction Administration
Once the project is under construction, your architect often stays involved to make sure the design intent is followed. This is when you are working with your General Contractor on the build.
Custom Homes: Project Timelines
Timeline: 10-18 months
Designing a custom home is deeply personal. Every decision—from the floor plan to the materials—reflects your lifestyle and taste. Because of this, the design process often takes longer, which is a significant part of the architectural project timelines.
• Design (4-8 months):
You’ll spend a lot of time working closely with your architect to get every detail right. Factors like a challenging site (e.g., steep slopes or limited access) or unique features (a spa, home theater, or custom finishes) can extend this phase.
• Permitting (1-3 months):
Residential permitting is usually more straightforward than for commercial projects, but delays can still pop up—especially if your design pushes the boundaries of local codes.
• Construction (6-12 months):
Building your custom home will likely take at least six months. The timeline depends on the complexity of the design, availability of materials, and contractor schedules. Custom finishes or specialty work can also add time.
Mixed-Use Commercial Projects: Project Timelines
Timeline: 18-36 months
Mixed-use projects are on a whole different level. These buildings typically combine residential, commercial, and sometimes retail spaces into one structure, making them much more complex to design and build.
• Design (6-12 months):
Mixed-use projects require architects to juggle multiple functions—residential layouts, commercial spaces, and public areas—while meeting strict building codes. This complexity adds time.
• Permitting (3-9 months):
Permitting for commercial projects can feel like a marathon. You might face additional reviews for things like environmental impact, fire safety, or zoning compliance. Be prepared for this phase to take longer.
• Construction (12-24 months):
These projects take time because of their size and complexity. Coordinating multiple contractors and trades, managing phased construction, and ensuring all systems integrate properly are just a few of the challenges that extend the timeline.
Key Differences in Project Timelines
| Aspect | Custom Home | Mixed-Use Project |
| Scope | Single-family residence | Multi-use (residential + commercial) |
| Design Complexity | Tailored to personal needs | Integrated systems, multi-functional spaces |
| Permitting | Simpler, faster process | Longer and more complex |
| Construction Time | 6-12 months | 12-24 months |
Keeping your Architectural Project Timelines on Track
Here are some tips to keep your project running as smoothly as possible:
1. Be Realistic About Timelines:
Building something meaningful takes time. Factor in delays—it’s better to be prepared than surprised.
2. Communicate Often:
Regular updates with your architect and contractor ensure everyone is aligned and working toward the same goals.
3. Be Prepared for Permitting Hiccups:
Whether it’s a custom home or a commercial project, permits can take longer than expected. Plan for this from the start. In fact, I have heard that every project has at least three big issues that happen. We work with you to reduce those potential issues but knowing they can happen helps prepare you.
4. Pick the Right Team:
Working with experienced architects and contractors who understand your type of project makes a world of difference.
