AI Floor Plan Generator Complete Guide 2026 | Planner 5D, Maket & Coohom for Home Plans
Want to draw home or renovation floor plans and 3D layouts with AI? Compare Planner 5D, Maket, Coohom, RoomGPT, ARCHITEChTURES, and Cedreo on features and pricing — plus building-code and safety cautions.
You want to sketch your dream home's layout yourself — you want to see a room in 3D after renovation — you want to build real-estate or architecture proposals fast. AI floor plan generators answer these needs. Enter the number of rooms and conditions, and the AI auto-generates a layout, producing everything from 2D drawings to a 3D walkthrough easily. The era of shaping home ideas without mastering pro software has arrived.
What is AI floor plan generation?
AI floor plan generation takes conditions — lot size, room count, requirements — and has AI auto-design and propose home or office layouts (floor plans), output as 2D drawings or 3D models. What once relied on architects and CAD software, AI now generates instantly as multiple plan candidates. Some tools read and clean up hand sketches, auto-place furniture, or reconstruct 3D space from photos, serving home design, renovation proposals, real-estate ads, and interior studies. The appeal is dramatically shortening early design study and ideation.
What you can do with AI floor plan generation
1. Auto-generate layouts from conditions: Enter lot, room count, and requirements to get multiple plan candidates. 2. 2D-3D conversion: Generate a 3D walkthrough from a floor plan. 3. Auto furniture placement: Lay out furniture to fit rooms and convey a sense of living there. 4. Import sketches and photos: Convert hand drawings or interior photos into digital plans or 3D space.
6 leading AI floor plan tools
1. Planner 5D
A popular tool for intuitive 2D plans and 3D interiors. With a rich furniture and material library plus AI features, even beginners can simulate realistic living spaces — good for home/renovation studies and hobby interior design.
2. Maket
An AI tool specialized in generating layouts from text requirements. Enter conditions like "3-bed with a south-facing living room" and it auto-generates multiple floor-plan candidates, speeding up early architectural studies and ideation. Its strength is design support for architecture and real-estate pros.
3. Coohom
A cloud tool strong in interior design and architectural visualization. It handles layout through high-quality 3D rendering and VR walkthroughs end to end, seriously producing proposal visuals for homes, stores, and offices.
4. RoomGPT
A simple tool that generates a renovated look from an uploaded interior photo. Rather than the layout itself, it suits before-and-after proposals that convert an existing room into a different interior style.
5. ARCHITEChTURES
An AI platform specialized in multi-unit and large-scale residential design. It generates optimal building plans factoring in codes, cost, and daylight, supporting developers' and design firms' feasibility studies.
6. Cedreo
A 3D home-design tool for home builders and remodelers. Quickly create layouts and 3D renderings to finish sales-proposal materials in a short time — good for strengthening on-site sales.

- Want fast 3D proposal materials for sales → Cedreo
Tips and cautions
The more specific your requirements (family size, needed rooms, priorities for daylight and flow, lot shape), the more practical the candidates. Compare multiple plans and map living flow and storage usability onto your own life. 3D renders greatly strengthen proposals and consensus-building.
The most important caution: an AI-generated layout is only an early-study starting point, and real construction requires legal and technical verification. (1) Compliance with building codes and ordinances (coverage/floor-area ratios, setback/daylight rules, seismic, fire, etc.) must be confirmed by a licensed professional such as an architect. (2) Structural safety, plumbing/equipment, and ground conditions cannot be settled by AI alone. (3) If using a floor plan in real-estate ads, represent it accurately to match the actual property. Use AI as a tool to accelerate study, and leave final design and verification to professionals.
Conclusion
AI floor plan generators shape home ideas in 2D and 3D without mastering pro software, greatly streamlining design study and proposals. Choose Planner 5D, Maket, Coohom, and others by purpose. Just remember generated plans are starting points — code compliance and structural safety always need an architect or other professional's verification. Accelerate study with AI, and make final decisions together with professionals.
