Ariadne Luchini is the founder of Line Arch Design and the person you will be talking to. She runs the design work, the drawing sets, and the permit submittals herself, and she stays on the project from the first call through construction. Technical work that requires an engineer's seal is qualified and sealed by our professional engineer, licensed in civil engineering in the State of Florida.
Read Ariadne's backgroundDesign, interiors, and civil work are delivered locally in Orlando and Central Florida, including Orange, Seminole, Osceola, and Lake counties. Elsewhere in Florida, documentation, permitting, and approvals are delivered remotely. Tell us the address and the jurisdiction, and we will tell you what the local process requires before you commit to anything.
A design firm coordinates the whole project under one point of contact: design, construction documents, and permitting. We develop the drawings, the engineering coordination, and the permit set as one connected process, so what you approve on screen is what gets built and priced. Nothing is lost between stages, and your builder receives a complete set instead of assembling one piece by piece.
Both. On the residential side we handle custom homes, additions, remodeling, and residential interiors. On the commercial side we design commercial buildings and mixed-use spaces. The same coordinated process applies either way: coordinating existing conditions, developing the layout, producing construction documents, and carrying the set through plan review until the permit is issued.
We serve clients throughout Florida. As a Florida licensed engineering practice, we are not limited to one region of the state. In person, our work is centered in Orange, Seminole, Osceola, and Lake counties. Everywhere else in Florida, projects are approved and documentation and permitting are delivered remotely, with local coordination arranged when a site visit is required.
We align on the scope of your project and take the time to understand your brief and your needs. We walk through the stages ahead and what to expect from each one, then identify exactly which services the project requires. You leave the call knowing the process, the sequence it follows, and what we would need from you to start.
Fees are built around the scope of each project. Architecture design, permitting, and interior design are each priced individually, so permitting is a separate service with its own price rather than something bundled in automatically. Scope is what drives the cost: whether the project is design alone, permitting, interior design, or a combination. We quote in writing after a scope call.
Active production, the work under our team's responsibility, runs 30 to 68 business days and averages around 46, roughly nine weeks. It excludes time spent waiting on your feedback, on third parties such as truss or engineering reports, and on city or county plan review, none of which is under our control.
We handle it. Our permitting team manages the pipeline with the city or county on your behalf, from submission through the comment cycle until the permit is issued, so you are not the one chasing a jurisdiction or interpreting a correction letter. Permitting is a separate service with its own price rather than something bundled into the design scope automatically.
You stay involved at every key decision point. Each phase requires your review and approval before the next one begins, so you give input and request changes as the design develops rather than only at the end. In practice that means approving the floor plan, then the exterior elevations, then the final set, with room to adjust at each of those points.
Send the address, the scope, and any drawings you already have. We will tell you what the project requires and what it costs to document, design, or permit it.
