Best Floor Plan Software

SmartDraw is diagramming software known for its intelligent formatting engine that automatically arranges shapes and connectors as diagrams are built. It includes more than 34,000 symbols and thousands of templates covering flowcharts, org charts, floor plans, network diagrams and engineering drawings, and can generate diagrams automatically from data such as org chart spreadsheets or AWS and Azure architectures.

SmartDraw is available as a web application and as desktop software for Windows and Mac, with real time collaboration and Visio import and export. It is sold on Individual and Team subscriptions billed annually, plus a custom priced Enterprise plan with SSO and dedicated support, and there is no permanent free plan.

SketchUp is a 3D modeling application from Trimble used across architecture, interior design, construction, and product design. Its signature push and pull tool lets users turn simple 2D shapes into 3D forms quickly, and the software is known for a beginner-friendly interface backed by the 3D Warehouse, a library of millions of pre-built models and materials that speeds up design work.

SketchUp is available on web, iPad, and desktop, with plans ranging from lightweight modeling to full professional workflows. Higher tiers add LayOut for 2D documentation, PreDesign for climate analysis, point cloud modeling, a Revit importer, and bundled V-Ray rendering. Over 1,000 extensions let studios tailor the software to structural, MEP, landscaping, and other specialized workflows.

AutoCAD, made by Autodesk, is a computer-aided design application used by architects, engineers, and designers for precise 2D drafting and 3D modeling. It supports solids, surfaces, and mesh modeling, automation through AutoLISP and APIs, and specialized industry toolsets for architecture, mechanical, and electrical design, alongside a lower-cost 2D-only variant called AutoCAD LT.

AutoCAD is sold by subscription, with individual list pricing commonly cited around $1,865 per year or $235 per month, plus multi-year term options and pay-per-use Flex tokens for occasional use. A 15-day free trial and free access for students and educators are available. Autodesk's official pricing page blocked automated access during this research, so figures here come from consistent third-party sources rather than a direct page fetch.

RoomSketcher produces accurate editable floor plans, published with industry provision, a downloadable application and monthly or annual billing including a free tier.

The professional output requirement is what distinguishes this from general drawing software, and it matters most in the industries that buy it.

An estate agent's floor plan is a marketing document that must be accurate, because a buyer relies on it and a materially wrong measurement is a legal problem rather than an error. It must also look consistent with every other plan the agency produces, since a portfolio of listings with inconsistent plans looks amateur.

That combination, measured accuracy plus consistent presentation, is what general drawing tools do not provide. A plan drawn freehand looks fine and cannot be relied upon, and one drawn in a CAD package is accurate and looks like an engineering drawing rather than a marketing asset.

Editability is the other requirement that sounds minor and is not. Properties change, listings are re-photographed, and a plan that must be redrawn from nothing each time will not be updated, so listings carry plans showing a layout that no longer exists.

The free tier makes this accessible to homeowners and occasional users planning a renovation, which is a genuinely different audience from the professional one and is served by the same tool because the underlying task is identical.

Pricing is published with monthly and annual billing, a free tier at $0 and $38 covering one user with the RoomSketcher App.
