Details
Questions, answered plainly
Is this the same product as FloorPlanMaker.app?
No. FloorPlanCreator.org is specifically for modifying existing homes—additions, second storeys, garage conversions, basements, attics, and as-built plans.
Are these construction-ready blueprints?
No. They are planning concepts. Have a licensed architect, designer, engineer, or contractor verify measurements, structure, code, and permit requirements.
Can I show existing and proposed work?
Yes. Describe which spaces already exist and which rooms or openings are new. The site’s tracing-paper visual language keeps that renovation context clear.
Are downloads free?
Yes. SVG and PNG export require no signup, payment, or watermark. Hourly fair-use limits apply.
