Room Designer

Draw rooms, place furniture, walls, doors and openings — including 3D walkthrough.

Room Designer turns your browser into a simple, powerful floor-plan studio. Whether you’re rearranging a bedroom, planning a garage workshop, or mocking up a remodel, sketch accurate plans in inches, place real-world pieces, and step inside with a first-person 3D walkthrough. WHAT YOU CAN DO • Set room width, depth, and ceiling height in feet & inches • Draw interior walls and place doors, plain openings, and windows • Drop furniture with custom names and dimensions (W × D × H) • Save reusable furniture presets (sofa, desk, tote bin — whatever you measure) • Snap openings to walls with hinge & swing orientation for doors • Select, drag, rotate, scale, and nudge objects with the keyboard • Copy & paste pieces to build layouts faster • Print measured plans for contractors, partners, or yourself • Save and load projects as JSON so your designs travel with you • Enter 3D Walkthrough: WASD move, mouse look, walk outside through doors and back in BUILT FOR REAL PLANNING Room Designer uses real units (inches), foot rulers on the plan, and clear labels so layouts stay practical—not just pretty sketches. Zoom and Fit keep large rooms readable; object labels in 3D make walkthroughs easy to understand. PRIVATE BY DESIGN Works offline after install. No account required. No tracking permissions. Your plans stay on your device unless you choose to save or export them. Perfect for homeowners, renters, organizers, makers, and anyone who thinks better with a floor plan.
