From Photo To Vision: Building a Tiny Internal Tool That Redesigns Rooms With AI

Sometimes innovation isn’t about giant platforms or complex enterprise software. Sometimes it starts with a simple “wouldn’t it be great if…”

We recently played with a concept: a small tool that lets you take a few pictures of a room, pick interior elements you’d like to change, and then uses AI to show you what the improved space could look like. Think of it as a visual imagination assistant. You shoot a photo. You choose things like “new couch,” “different color scheme,” “Scandinavian vibe,” or “add bookshelves.” The tool turns that into a structured prompt and generates a realistic vision of your future room using Nano Banana as the image engine.

And yeah, it actually works surprisingly well.

Why build something like this?

Because a lot of decision-making is visual.
People struggle to imagine change. Whether you are renovating a house, designing an office, setting up a studio, or even arranging furniture for better workflow, you want to see before you commit.

Normally, that means:
• talking to a designer
• lots of back and forth
• mockups, revisions, waiting

The customer wanted something instant. Something playful but useful. Something lightweight that they could use without needing a full production design team every time.

The idea in plain words

Here’s what the tool does in simple terms:

1. You take photos of your room.
2. You pick some interior elements or style preferences.
3. The tool automatically builds a very specific AI prompt.
4. Nano Banana generates a realistic image of “your room, but upgraded”.

So instead of guessing, you see:

“This is what your space could look like.”

That changes the conversation completely.

But it’s not “just for fun”

Sure, it’s cool. But there’s serious value here.

The company we made this app for uses it for things like:
• office redesign decisions
• retail store layout ideas
• hospitality interior refreshes
• studio setups
• concept visualization for clients
• content creation and marketing material thinking

It lowers the barrier between idea and reality. It lets teams experiment visually without cost, without delay, without stress.

How we approached it

Like always at Emplex: start small, scale up, real feedback.

We started with:

“What is the simplest useful version?”

So we focused on three things:
• clean photo upload
• intuitive selection of interior elements
• smart prompt generation that actually understands context

We let AI do the heavy lifting but we keep control over the structure. The user stays in charge. The tool assists, not replaces.

This is what we love building

This little project represents what we believe in:
practical AI, not hype
real usefulness, not gimmicks
things that actually help people make decisions

We like tools that shorten the distance between thinking and doing. Between idea and execution.

Sometimes that’s a huge logistics platform.
Sometimes it’s a quiet little internal app that helps you redesign a room.

Both matter.

Thinking about something similar?

If you’re a company that constantly says:

“we should visualize this better”

or

“it would be great if we could quickly test ideas before spending money”

then this type of tooling is probably something you’ll love.

We help organisations build exactly these kinds of smart, focused internal solutions. Fast, safe, and tailored to how your team actually works.
