Foursite by VirtualSpaces: From Floor Plan To Lived Experience

Hey Product Hunt,

I have been working closely with teams who design and sell homes for a while.

The same issue keeps showing up: buyers cannot translate 2D floor plans into how a home will actually feel.

They squint at drawings, nod politely, then walk the finished unit and say: “This feels smaller than I imagined.”

That is the gap we are trying to close with Foursite, built by the team at VirtualSpaces.

Foursite takes the documents everyone already has: 2D floor plans and Blueprints.

You upload them, and the platform converts blueprint to 3D in minutes.

You get a precise floor plan to 3D model, then layer on AI interior design, AI interior décor, and AI virtual staging to bring each home to life.

No heavy CAD expertise.

No long render studio queues.

No “trust me, it will feel bigger in real life.”

A typical use case looks like this:

• Architects and designers upload 2D floor plans from ongoing projects

• Foursite runs its 2D to 3D engine and builds an accurate 3D Visualization model

• Teams explore AI 3D visualization together, test layouts, and generate interior design renders on the fly

• Marketing pulls interior design photoreal renders from the same model, and uses AI virtual staging to tailor visuals to different buyer profiles

The goal:

Design spaces for people, not just for drawings and sales decks.

When a buyer asks “how will this feel with my furniture and my routines,” you can show them in minutes.

A few principles behind the product:

• Start from real constraints: 2D floor plans and Blueprints stay the source of truth

• Collapse hand offs: convert floor plan to 3D once, reuse everywhere

• Keep humans in charge: AI visualization suggests, designers decide

We wrote a deeper piece on the thinking behind this if you want the behavioral psychology and spatial cognition angle.

Would love feedback from:

• Interior designers tired of juggling five different tools for one project

• Residential developers trying to speed up pre sales without overpromising

• Architects who care about honest, build aligned 3D Visualization

• Homeowners who have ever said “I just cannot picture it” while looking at plans

If any of that resonates, I would really appreciate your thoughts and questions on Foursite.

Cheers!
