We Built Foursite Because Floor Plans Deserved Better

We come from engineering, not from interiors. That’s important context.

Because when we first looked at the interior design workflow, we saw it like developers. We saw a pipeline full of blocking tasks. Hand-offs. Manual rebuilds. The kind of stuff you’d refactor immediately if it were code.

Think about the starting point. You get 2D floor plans or old Blueprints. Sometimes they’re clean. Sometimes they’re just photos of paper. From there, the typical path looks like this.

Redraw.

Model.

Export.

Render.

Send to Virtual Staging.

Wait.

Revise.

Repeat.

Designers we spoke to were doing world-class work. But they were doing it on top of brittle infrastructure.

Foursite, inside VirtualSpaces, is our attempt to fix that plumbing.

At its core, it’s an AI interior design and AI Visualization rail.

You drop in 2D floor plans. We handle 2D to 3D. You share Blueprints. We handle blueprint to 3D. Under the hood, we convert floor plan to 3D and convert blueprint to 3D as accurately as we can.

Walls.

Openings.

Basic structure.

All rebuilt with AI 3D visualization.

Once the space exists, the interesting part begins.

Designers can run AI virtual staging to get a first pass. They can apply AI interior décor to test different aesthetics. They can treat Virtual Staging as a sketch layer, not an outsourced black box. They can control the story, but skip the file gymnastics.

For us as techies, the “aha” moment was simple.

The magic isn’t in one render. It’s in how fast you can explore ten options.

Foursite lets a designer see what “warm minimal” vs “soft industrial” actually looks like in the same apartment, in the same afternoon. It keeps the human at the centre. It just stops punishing them every time they want to try a new idea.

We didn’t write the blog as a product pitch.

We wrote it as a map of what changes when 3D Visualization is no longer a bottleneck.

If you care about residential spaces, or you build tools around them, this is the question we’re exploring: what happens when the limiting factor is no longer software, but imagination?

Foursite is our first answer.

The rest, we’re still learning in public.

Cheers!
