Design Fiction: The In-Home Window Visit

A software engineering and platforms company from Silicon Valley that builds digital products and AI solutions for its customers. They were building a tablet app for one of their customers, a windows and doors business. The app is for the sales visit in the homeowner's house.

They had the engineering side covered, so what they wanted from us was the experience: how the visit should feel for the family and for the rep. This film is our answer.

What if buying new windows and doors started with a conversation, not a catalogue? This film imagines an iPad app that a sales rep brings into the customer's home. The homeowner says what they want to feel in their home, like more light, less street noise, or a front door that feels like theirs.

The app scans the house, finds every window and door, and shows each change on their own home as they choose. The price updates with every choice, so nobody waits till the end for a surprise number. The rep stays in charge, and the AI only suggests and explains.

Home windows and doors, sold by a rep sitting at the kitchen table. It's a big decision for a family. In the US, a window replacement job comes to about $22,000 on average (Cost vs Value report, 2025).

Still, most families decide from paper brochures and small samples, and they never really see the result on their own house before they sign. After signing, the order often gets measured, re-typed and changed again before anything is built.

Emma is a homeowner with a 1990s house and twelve old windows. She doesn't know the product terms and doesn't want a hard sell. She wants to know how the living room will feel, what it will cost, and that what she signs is what gets installed.

Next to her is Daniel, the rep. He has to explain hundreds of options in one evening without overwhelming her.

• A short talk first, so the design starts from how Emma wants the home to feel.
• One scan of the house that finds every window and door.
• Changes shown on her own home, outside and inside, morning to evening.
• AI suggestions that say why and what they cost, and the rep decides.
• One clear price for the whole home, with two other options to compare.
• Sign at the table, then the design stays with her on her home screen.

We studied how these visits work today, then mapped the full journey from the first call to install day. Then we designed the iPad screens and turned them into a short film, so the client could feel the visit, not just read about it.

Design fiction is how we test an idea before anyone writes code. The scan, the AI and the price you see here are imagined. Nothing in the film is a live product, and no real customer data is used.
