HouseStage AI interior design · 3D walkthrough
AI interior design, checked by a real designer
HouseStage uses AI for the slow parts of interior design: reading your floor plan for room sizes, turning your answers into a design brief, suggesting real furniture that fits each room, and rendering the result. A 126 Design designer reviews and approves every one of those steps before you see it. You get a room-by-room plan you can actually order, plus a 3D walkthrough of your home.
What the AI does, and what the designer checks
| Step | AI | 126 Design designer |
|---|---|---|
| Read the floor plan | Pulls each room's name and dimensions out of the floor plan. | The designer checks the numbers against the plan before anything is sized from them. |
| Write the design brief | Turns your questionnaire answers (style, budget, move-in date, household, priority rooms) into a brief for each room. | The designer reads it, fixes what the AI misread and adds what only a conversation catches. |
| Suggest furniture | Proposes real, orderable products whose dimensions fit the room. | The designer swaps, removes or adds pieces. Nothing goes to you unreviewed. |
| Render and check | Renders the plan from the 3D layout, then compares the image with the layout to catch furniture that was moved, swapped or left out. | The designer approves the final images, so what you see is what is actually in the proposal. |
The AI makes the work faster. It doesn't make the decisions. The designers behind HouseStage have staged 1,600+ Bay Area homes, and they know things a model doesn't, like how a family actually uses a room and which pieces hold up to kids and pets.
AI design apps vs. HouseStage
AI room design apps are great for trying a look in seconds. They're built for inspiration, though, not for furnishing a house. Here's where the two differ:
| Typical AI room design app | HouseStage | |
|---|---|---|
| Starts from | A photo of the room | Your floor plan, with room dimensions |
| What you get | Rendered images | An itemized, room-by-room plan, plus renderings and a 3D walkthrough |
| Furniture | Often generated; may not be a product you can buy | Real products with SKUs, prices and lead times |
| Fit | Usually not checked against real sizes | Checked against each room's dimensions |
| Review | None; you judge the image | A designer approves every item and image |
| Getting it into your home | You shop for it yourself | 126 Design orders, delivers and installs it |
3D walkthrough and virtual home tour
Every buyer page can open a first-person 3D walkthrough built from the home's floor plan, with a mini-map that follows you around. Once your proposal is ready, the walkthrough shows the actual pieces from it in each room, and tapping a piece takes you to it in the proposal.
- Open the public sample walkthrough. It runs in a regular browser, no app needed.
- On a headset, open the same page in the Meta Quest 3 browser or in Safari on Apple Vision Pro and choose Enter VR to walk through the rooms at real scale (WebXR).
- Walkthroughs help you judge how a room feels before buying for it: whether the sectional crowds the doorway or the dining table leaves room to move.
An online interior design service, with people where it counts
You don't need to book a consultation or create an account. Open the private link from your agent or your closing card, answer the questionnaire in about five minutes, and the proposal comes back to the same page. 126 Design's team then handles the in-person work: custom curtain measuring and white-glove delivery and installation.
HouseStage is set up for homes 126 Design has staged in the Bay Area, since that's where we have the floor plan and know what was in each room. If you liked the staging, you can keep it: see buying the staging furniture.

Questions about AI interior design
Is the design done by AI or by a person?
Both, with a person in charge. AI does the first draft: reading the floor plan, writing the brief, suggesting pieces that fit and rendering the rooms. A 126 Design designer reviews and edits each of those before anything reaches you.
Can I buy the furniture in the AI design?
Yes. Every item in a HouseStage proposal is a real product with a SKU, dimensions, finish, lead time and price. When you approve the plan, 126 Design orders, delivers and installs it.
How is this different from an AI room design app?
Most AI room design apps generate a picture from a photo of your room. That's useful for ideas, but the furniture in the picture may not exist, and nobody checks whether it fits. HouseStage starts from your floor plan's measurements, only suggests products you can order, and has a designer approve the plan.
Can I see my home in 3D or in VR?
Yes. Your buyer page includes a 3D walkthrough built from your floor plan, with the furniture from your proposal placed in each room. You can try a public sample at housestageusa.com/tour. In the Meta Quest 3 browser or Safari on Apple Vision Pro, tap "Enter VR" to walk through it at full scale.
Is this an online interior design service? Do I need to meet anyone?
The design side happens online: questionnaire, proposal and approval all happen on your buyer page, no login required. People come to the house for the parts that need them, like measuring for curtains, delivery and installation.
