Midda: from the contractor's sales plan to a 3D apartment at real size
A Hebrew-first web app that turns an apartment sales plan into a place you can walk through: upload the PDF, calibrate it in two clicks, trace walls with live sizes, and get a 3D apartment with furniture at real dimensions. Plus a series of reels produced from the product itself.

18 cm is a lot: the warning that catches a tracing slip (in Hebrew)
The problem
Buyers of a new apartment get one sheet of lines and numbers, and have to decide on the kitchen, closets, furniture and layout changes from it long before there is an apartment to step into. A drawing is hard to picture as a space, and a few centimetres off is invisible until the kitchen is already ordered for the wrong wall.
What we built
- A browser editor, Hebrew and right-to-left from day one: upload a sales plan (PDF or image), calibrate it with two clicks on a known wall and one typed length, and trace walls, doors and windows with live sizes
- One geometric model that everything comes from: net area per room, warnings next to the wall when a size contradicts the plan, and locked safe-room (mamad) walls
- A 3D apartment built instantly from the same walls: a dollhouse view and a first-person walk at eye level, on desktop and phone
- A furniture catalog at real sizes plus custom pieces, clearance checks, modular kitchens and closets, floor and wall finishes, and "Will it fit?", which checks a piece's route from the front door to the room
- Bill of quantities and budget, layout variants to compare and decide on together, PDF export, and WhatsApp share links with a preview image
- Accounts that sync across devices, autosave with unlimited undo, and one-time payments in shekels (no subscription)
- A landing page with a scroll story that ends in an interactive demo apartment, running on the editor's own engine
- A series of 9:16 reels in Hebrew: real editor captures and 3D footage from the engine itself, edited in code with Remotion
The result
- A live product at midda.idone.co.il, with a free plan and one-time paid plans from ₪49
- In the acceptance test, a new user went from uploading the sales plan to walking through the apartment in 10:55 minutes (the target was under 20)
- Room areas computed by the editor came within 0.6% of the plan's reference file
- Three reels that show the product as it really works, with no shoot, from the same team that built it
