The render is gorgeous. The sofa is perfect, the rug is the exact right size, the curtains fall in soft folds, and everything fits like the room was built for it.

Then the real furniture arrives.

The sofa doesn't make the turn in the hallway. The bookcase is two inches too tall for the ceiling — which, it turns out, isn't even the same height on both ends of the room. The rug is so big the door won't open. And the return freight on that sofa, plus the restocking fee, runs into the thousands.

This is the moment we keep getting called about — after the purchase, not before. AI design tools are remarkable at imagining a room. What they cannot do is measure one. Design should start with designing — not detective work.

What AI can't see

An AI render works from a photo and a guess. It doesn't know:

• Whether the piece fits through your front door — or around the tight turn in your building's hallway, or up the stairwell landing
• Your real ceiling height. Wonky, out-of-level ceilings happen more often than you can imagine — and they're the silent killers of curtain and wallpaper installs. Curtains hem uneven on one side; the wallpaper pattern won't line up at the seams
• Curved walls, which bend every "standard" measurement out of shape
• The elevator. Whether the piece fits in it, whether your building requires a freight-elevator reservation and a certificate of insurance, and what a refused delivery actually costs you
• Door swings and walk paths — the dining chairs that can't pull out, the recliner that can't recline
• Outlets, vents, and returns hiding exactly where the render put your furniture
• Lead times. The AI doesn't know your perfect chair takes 14 weeks and your lease starts in 4 — or that the item was discontinued last spring

Every one of these is a real charge on somebody's credit card. Return freight and restocking fees of 15–25% are standard — on a sofa, that's thousands of dollars for the privilege of sending it back.

The fix: Will It Fit? — the AI Design Check

So we built the service we kept wishing clients had used first.

Will It Fit? — the AI Design Check takes your AI design and shopping list and checks them against your actual room, measured properly:

1. We measure the real space. Using LiDAR-based measurement (Twindo), we capture verified dimensions of your room — including ceiling heights, door and hallway clearances, and the delivery path from the street to the room.
2. We verify the fit. Every piece on your list gets checked against the real numbers: will it fit, will it get in, does the swing clear, does the walk path work, will the curtains and wallpaper survive your actual walls and ceilings.
3. We audit the list. Wrong sizes, discontinued items, lead-time traps — flagged before your card comes out, not after the truck arrives.
4. You get a corrected, shoppable list. Same design you loved, fixed to fit your real room — with links you can buy from directly.

What we verify is dimensions, fit, and the accuracy of your list. We don't certify anything structural — that's an engineer's job, and we'll tell you plainly if you need one.

What it costs

The check is priced on our standard measurement structure — a flat total confirmed in writing before work starts, starting at $1,375. Half books the appointment; the balance is due when your corrected list is ready, before it's released.

And here's the part that makes it an easy yes: if you hire San Diego Office Design for the design work within 60 days, 100% of the check fee is credited toward your design. The check is free if we end up doing the room — and cheap insurance if we don't.
