Custom Home Design

Our process begins with an initial layout and develops through each stage of the design, giving you opportunities to review and provide feedback along the way. Depending on the project, this may include floor plans, elevations, and other design details needed to move the project forward.

Starting at $3.00 per heated square foot & 50 cents per unheated square foot*


*Square footage break down: Cost is for heated square footage as well as rooms & spaces designed for future completion (for example an unfinished bonus room or FROG). Unheated spaces include porches, decks, garage and drive under space.

Detached garages needed for whole house design projects will be quoted on a case by case basis.

Renovation & Addition Design

Make your existing home work better for you. Renovations and additions require a different kind of design thinking. We start by understanding what you have, what isn't working, and what you want the space to become. We'll visit the property, take measurements and photos, discuss your goals, and develop a design based on the scope of your project. Pricing is determined on a case-by-case basis based on the size and complexity of the project.

Drafting Services

Have a plan that needs to be redrawn or updated?

We offer drafting services for clients who need plans created, modified, or redrawn in CAD.

Drafting Services
$125/hour with a $500 minimum*

Plan Re-draws
Plan re-draws starting at $2.00 per heated square foot**

*This rate applies to changes a customer may need to make to a plan once they have used up all the plans changes allowed in the contract. This may also apply to an electronic plan you have purchased over the internet and have changes you would like to make.

**This is to redraw a set of plans you have on paper and need to be redrawn in CAD. A price will be negotiated for any plan changes.

Pricing is for design & drafting services only. Engineering is required and is a separate cost. South Carolina complies with the IRC (International Residential Code) and engineering is required to meet those guidelines. I will be happy to obtain an engineering quote for you or you are welcome to use your own engineer.

How It Works

Every project is different, but our process is designed to give you clarity along the way. We'll ask questions, develop the design in stages, and work with you through the decisions that shape your project.

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 8–12 weeks. Engineering and other third-party services may affect the overall timeline.
