Planning a renovation before you commit

You own the place, and somewhere there is a drawing of it: an architect’s plan left by a previous owner, or a page from the building’s file. You want to see what the space could become before you pay anyone to start. Until then the idea lives in a description, and everyone in the conversation pictures a different room.

L-shaped home, whole space: AI-generated visualization of the reference 3D model.
The shared living space turns toward a separate bedroom wing. AI-generated visualization; explore eight views and their source captures below.

What you can do

  • A navigable, conceptual 3D reconstruction of the drawing.
  • Modeled spaces to inspect against existing conditions, with direct manual controls for conceptual wall and opening corrections.
  • Model-space area, space count, height and extent estimates in the viewer.
  • Furniture and finish options that remain separate from the original reconstruction.
  • A saved-revision GLB and a JSON room map of boundaries and doorway connections, each listed with its byte size and SHA-256.

Limits to keep in mind

  • It is not a survey and it is not a construction document. Nothing here is stamped, and nothing is checked against a building code.
  • Preserve a saved baseline and source drawing for comparison. The manual editor can edit conceptual walls, openings and levels in the proposal; an edit does not establish structural safety.
  • The model download does not include a priced scope of work. Confirm quantities and costs separately.
  • Select PDF pages and crops in the local preparation workspace. Group fragments by physical floor before uploading; every plan supports homes with several levels, up to its floor limit.
  • No unchecked automatic stacking. On any plan, the building flow can combine several floors up to your plan’s floor limit, but you must review alignment, elevations and stair connections before confirming the model.

Features you can use

Existing conditions review

Compare the reconstruction with the drawing and keep a baseline option. Editing requires purchased access; critical dimensions still need field verification.

Design Options

Keep an existing-conditions option as your saved baseline and edit the proposal in another option. Furniture, finishes and conceptual manual wall and opening changes can vary; retain the separate source drawing for comparison.

Furniture library

Each piece prints its width, depth, and height, the clearances it needs, and its license. Those figures are catalog bounds, not a verification of the real room. Saved-project Fit check evaluates one placement against the model.

Finishes

Apply a material to a room floor, wall or fixture. Use a larger screen for precise placement and dimension checks; the sample is available before you start your own project.

Measure tool

Choose two points to read a distance within the conceptual model. The tool does not calibrate the model or change it.

Revision history

Manual mode shows the revision history. Every change saves a revision, and restoring an earlier one writes a new revision instead of erasing the current one.

For current controls and account requirements, use the editor manual.

Compare the model and the images

Choose an angle, then move the divider to compare the original 3D view with its generated image.

What happens when you upload an old drawing

You make a project for the home and upload one floor plan: a PDF, SVG, DXF, PNG, or JPEG file of 25 MiB or smaller. The conversion uses one available import. The file is checked, then the workflow reads the drawing, traces walls and spaces, closes gaps, saves the model, draws the base plan and raises the 3D model.

You can close the tab; the work continues on the server. The progress screen shows completed processing steps rather than estimating time remaining or measurement accuracy.

Processing can also stop without failing. Where the workflow cannot convert a drawing automatically, the screen says Not available yet. Any model that returns is still conceptual: drawing context and known lengths provide scale evidence, and supported homes can be rebuilt from a measurement into a fresh option. Existing drawn options retain their old scale; no accuracy tolerance is established. Compare its geometry with dimensions printed on the source and check the critical ones on site.

What to check before you plan anything on it

An old drawing describes a building as it was drawn, not as it stands today. A wall gets moved, a door gets filled in, and the page in the drawer records neither. Check the model against the drawing, and the drawing against the building, before you plan around either.

  1. Compare the model-space extent with an overall dimension printed on the drawing. If they differ, treat the model as an interpretation to correct, not as a measurement of the building.
  2. Take a tape to one wall on site, and make it the wall you most want to change. A mismatch is a reason to check the rest of the drawing; one matching wall does not verify the whole plan.
  3. Compare the space count and model-space area estimate with the home you know. A plan and a deed can disagree about area for ordinary reasons, which is its own subject: why your plan and your model disagree about the area.

Keep the source distinct from the proposal

Review the reconstruction before proposing changes. Design Options keep furniture and finish variants distinct from the source; the manual editor also allows direct conceptual wall and opening corrections. Keep an existing-conditions revision, label the proposal clearly and check scale and critical dimensions on site before ordering or building.

Design Options separate furniture and finish proposals from the source reference. The manual editor also exposes direct wall, door and window tools on the same canvas. Save and label conceptual geometry changes separately, then ask the responsible professional to check structure, services, permits and construction dimensions; the editor does not approve those decisions.

When the change you want is a wall

Many renovations begin by moving a wall. Keep the reviewed source as a reference, then use Expert tools for a conceptual wall or opening change. Guided shows common tasks and Expert exposes direct controls on the same model. Structural work still needs verified site conditions and a qualified drawing.

Plan the changes the editor supports

Use Design Options to compare furniture and finishes while keeping the reviewed reconstruction as reference. Processing a new physical floor uses one floor unit. Manual edits and alternatives on that floor are included; export formats vary by plan. The project creator or an assigned customer Editor with an available seat can use the export library, and only while the project is nonpublic. the pricing page explains current access.

If you are going to show this to a contractor

Say what it is before you open it. It is a conceptual model built from your drawing, and the model download does not include a quantity estimate or quote. The download is a GLB scene and a JSON room map of boundaries and doorway connections, each listed with its byte size and SHA-256, so you can identify the saved or compiled revision you handed over.

If the contractor wants dimensions to order from, verify them on site before placing the order. Reading a measurement off a drawing is its own job, and reading distances from a plan model covers what a conceptual model can and cannot settle.

What the example demonstrates

In Isla de Pascua, original SketchUp and plan dimensions were refined through MCP/AI using photographs and video. It is a visual interpretation, not a certified survey or evidence of automatic conversion without review. Compare your model with your own source and record decisions that change the interpretation.

Your next decision

Label existing conditions and the proposed revision separately. Give the contractor the chosen conceptual option, the source and a list of measurements and permissions still needing approval.

Guided shows common tasks and Expert exposes direct controls on the same canvas. Assistant changes require an available allowance. The drawing remains the reconstruction reference. The account, editor and billing application currently use English.

You see your home in 3D before you pay, and editing it needs a plan. A failed build goes back to your monthly builds. Check access and pricing before you begin.
