Structural Engineering is required and is provided by a third party at a separate cost. South Carolina complies with the IRC (International Residential Code) and engineering is required to meet those guidelines. We can assist with engineering coordination, if needed.
How It Works
Start with a conversation.
We'll learn about your property, your goals, your budget, your lifestyle, and what you want from your project.
Depending on the project, we'll discuss things like:
- Property surveys
- Flood zones
- Square footage
- Number of stories
- Layout preferences
- Lifestyle and family needs
- Budget
- Existing conditions
The goal: understand what you're trying to accomplish before we start drawing.
Turn ideas into a thoughtful design.
For a custom home, we typically begin with an initial floor plan and develop the design from there. You'll have opportunities to review the design and provide feedback as we work through the layout, additional floors when applicable, elevations, and other details.
For renovations and additions, we'll begin with the existing home and develop a design around what you want to change.
The goal: create a design that reflects your vision while making sense for your property and priorities.
Work through the details.
As the design takes shape, we'll refine the plans based on your feedback and the requirements of the project.
If your project involves an ARB or other review requirements, those considerations become part of the process as well.
The goal: make thoughtful decisions before moving on to the next stage.
Bring the right pieces together.
Depending on your project, this may involve coordinating with an engineer and helping you understand what comes next with permitting and construction.
Crosby Creations can also help point you toward the professionals you'll need to move your project forward, including engineers and builders.
The goal: help you feel informed about what's next instead of figuring it out on your own.
Take your next step with confidence.
Once your design is complete, you'll have a clear set of plans and a better understanding of the next steps for your project.
And our relationship doesn't necessarily end when the plans leave our office. We're happy to communicate with your builder if questions about the design come up along the way.
Every project has its own timeline.
The time required to complete a project depends on its size, complexity, our current workload, how quickly we receive feedback, and whether additional review or approval is required. For a typical custom home without an ARB and with timely client feedback, the design process generally takes 4 to 6 months. Minor renovation, and addition projects generally take 6 to 10 weeks while major renovations and additions may take up to 12 to 18 weeks. to complete. Engineering and other third-party services may affect the overall timeline.
