Free 3D sketch editor for replanning: trace your current plan, build a new variant and compare — before paying for design documentation and demolition.
Important: we're a sketch tool. We do not identify load-bearing walls, don't assess whether changes are legal, and don't consult on approvals — that's the work of a licensed design firm and the housing inspection. Our job is to help you see the idea and decide whether it's worth going to specialists.
Four tools that cover the sketch stage — before ordering design documentation and dealing with the housing inspection.
UniqueReplanning an apartment with AI: hit 'generate design' — the AI creates a photorealistic render of the new variant: wallpaper, floor, lighting, furniture. The main argument against the family's doubts: not a drawing but a photo of the future. Replanning by photo + AI — the only way to show 'and how it would look'.
Trace the current plan from a BTI floor plan photo and save it. Then in a new file build the 'how it could be' variant — virtually knock down partitions and put up new ones. Both projects live in your account — compare by area numbers or switch between them.
Apartment replanning online by photo: upload a scan or photo of the technical passport, developer's plan or paper drawing — it appears as an underlay in the editor. Trace the room contour by clicking corners; the editor computes areas. No need to enter dimensions by hand.
Walk through the apartment that doesn't exist yet: how the kitchen-living reads without a wall, whether the room got brighter after knocking down a partition, how the new bathroom looks. Easier to decide while walls are on screen, not after renovation.
UniqueReplanning changes room geometry — your furniture stays the same. Photograph your sofa, wardrobe, dining table — the AI builds their 3D models with real dimensions and places them in the new variant. See whether the replanning works with your actual furniture, not with abstract catalogue pieces.
From empty screen to a photorealistic 'before/after' sketch — an evening. Signup only to save the project.
Upload a photo of the BTI plan or technical passport — an underlay appears in the editor. Trace the room contour by clicking corners, mark doors and windows. The editor computes areas itself.
Save the current plan and create a new file — this is where we work. Partitions move in seconds: knock down one, put up another, compare areas. You'll cycle through 3–4 ideas in an evening and see which one works.
Switch to 3D and walk through both versions. A render instead of arguments: the family sees not a drawing but a photo of the future. Easier to agree on the plan than in conversation.
Download the version you like as PDF and take it to a licensed design firm. They'll tell you what's technically feasible, assess load-bearing walls and wet zones, and prepare design documentation for approval with the housing inspection. Our sketch is the language of the conversation with them — not a substitute for them.
Six real-life scenarios most often drawn in the editor. For each — what you'll assemble here and what to ask the designer at the first meeting.
Wet room without a partition, full-size tub plus washing machine, +30% area. One door instead of two.
Whether you can extend into the corridor in your building, where to move risers, how to insulate the floor under the wet zone.
One space: cabinets + island as a zone boundary, sofa back to the kitchen. The wall between kitchen and living virtually knocked down.
Whether this wall is load-bearing; what about the gas stove — for gasified kitchens the rules differ; ventilation after removal.
A bedroom fenced off with a new partition deep in the apartment, everything else becomes a kitchen-living. Bedroom door — from the common space.
Whether there's enough natural light in the new bedroom; norms for 'euro format'; whether lightweight partitions are allowed in your building.
2–3 m² is fenced off from a bedroom or hallway for a walk-in: rods, shelves, shoes. Door optional — just a partition.
Whether the remaining room area meets norms; whether approval is required for a lightweight partition in your building.
New doorway in the side wall + old passage closed off. The room becomes isolated with one door.
Whether you can cut a doorway in this wall — its load-bearing status decides everything; what to seal the old passage with.
What the apartment would look like if the wall between the room and loggia were removed — a unified space with panoramic glazing.
This is one of the most restricted scenarios — mandatory to see a designer before any hopes. Ask about radiators and the under-window block — those are what discussions usually stop on.
The common thread across all scenarios: draw here — take the sketch to a specialist. The legal side (what's allowed, what's not, in your building) is the designer's job — the block below sets the boundary of responsibility explicitly.
A direct boundary of responsibility. Honestly: the sketch costs nothing but an evening; design documentation and approval are separate money for specialists. Our page helps you understand whether the idea is worth that money.
Take this list to the designer. We formulate the questions, the specialist gives the answers — that way you won't waste the first meeting on general talk.
Replanning usually affects specific rooms — the bathroom, kitchen, kids room. You can build their sketches on the dedicated pages.

Replanning has two kinds of services: approval firms (sell a service) and regular online planners (don't know the 'before/after' format). Our editor is the sketch stage between a family decision and the visit to the designer.
Details. Approval firms sell a service: their sketch starts after you sign the contract and pay a deposit. With us — free and before any decisions. Build the idea here, look in 3D, show the family — then go talk about money.
Details. Regular online planners draw one apartment. We're built for comparing two: the current BTI plan and the new variant live in one account as two separate projects. Switch between them, review areas per project. Plus AI render of the new variant — regular builders don't have that.
Details. We have a dedicated 'What we do — what we don't' block that spells it out: we don't identify load-bearing walls, don't assess legality, don't prepare documentation. We're a sketch, not a designer. That kind of frame usually lives in the footer in fine print — with us it's centre stage.
Details. Replanning is one of the templates inside the apartment planner. Built a replanning sketch — open the bedroom, bathroom, kitchen templates next in the same account. The project lives before and after renovation.
Real replanning sketches built in our editor. Left — the BTI plan, right — the 'how it could be' variant. AI render added to a pair to show the family a photo of the future, not a drawing.
PDF sketches 'before' and 'after' — for the designer and family. PNG render of the new variant — for family and contractor. Public link — for discussion with a specialist or relatives.
What people say who already ran variants here — before going to a designer, before demolition, before paperwork.
«We ran four versions of taking down the wall between the kitchen and the living room, and the render is what stopped us — that wall was buying us 20 square feet of usable corner and keeping dinner smells out of the rest of the house. So we passed. Some weeks I think that was right and some weeks I stand in that doorway and wonder.»
«I walked into the architect's office with a before-and-after PDF instead of a notebook full of arrows. Half an hour later I knew the bearing wall stays and the plumbing can move. We signed the drawing contract at the second meeting, not the fifth.»
«It's my mother's house, and she was against turning the half bath under the stairs into a full one — said it would feel like a gas station. I showed her the render with the tile and the glass panel and she stopped arguing. A picture did what six months of talking couldn't.»
«The design firm wanted $600 for the as-built before they'd quote a thing. I borrowed a laser measure, drew it here myself and sent it over. They went straight to load calculations and never brought the sketch up again.»
Sketch 'before', sketch 'after', 3D walkthrough and PDF/PNG export — free forever. Only AI render of the new variant and photo extraction of your furniture cost tokens.
Eight specific questions people ask most often about the sketch stage of replanning.
Build the 'before' and 'after' sketches in an evening, compare in 3D, show the family and get an AI render of the new apartment. Liked it — take the PDF to a designer. Didn't like it — saved money on a project you don't need.
