About JC Drafting & Design

Full Service Home Design Firm

JC Drafting & Design, Inc. is a family-owned residential design firm based in Sarasota, Florida.

Experience

For more than 50 years, founder Jon Coulthurst has specialized in residential design, creating custom homes, renovations, additions, ADUs, and permit-ready plans across Sarasota and Southwest Florida.

Education

We know the complexities of Sarasota geography: flood lines, coastal setbacks, topography, FEMA requirements, and HOA rules. Before we design, we confirm your home can actually be built.

Collaboration

Working with us is a back and forth between your vision and our experience. We help clients move from concept to construction-ready plans through close, ongoing conversation.

Bringing the pieces together

Every successful project begins with a vision. Your ideas, lifestyle, property, goals, and budget are the pieces of the puzzle. Our role is to bring those pieces together into a thoughtfully designed home that is beautiful, functional, and uniquely yours.

The firm combines decades of residential design knowledge with advanced technology, including 3D modeling, photorealistic renderings, Matterport scanning, as-built documentation, drone footage when needed, and virtual walkthroughs that help clients see and understand their projects before construction begins.

One of our greatest strengths is extensive knowledge of Florida residential building codes, local zoning regulations, and permitting requirements. We also work closely with a trusted network of structural engineers, civil engineers, surveyors, and contractors to help coordinate projects from concept through permitting.

Why Homeowners choose us

At this point, your home is a thousand small decisions. What should the view from the kitchen look like in the morning? How many steps from the bed to the closet? Which moments in your home matter most?

Your new home design is a collaborative effort between you, your designer, and your builder. Starting with a solid design means your home is built on a solid foundation.
