I'm one of the founders of Foursite. We've been quietly building for the past two years, and we've launched because we think we've solved a real problem that nobody's talking about.
My co-founder and I are not designers. We re not architects. We ve never held a blueprint or studied color theory. We re just builders who got tired of hearing the same problem over and over.
Interior designers are burned out.
Not because design is hard. Because the logistics of selling design is brutal. A designer spends 32-46 hours creating a proposal. They sketch. They source materials. They create mood boards. They render concepts. Clients look at 2D floor plans and say I don t get it. So designers start over. And over.
We re builders, not designers. But we ve spent the last two years watching interior design workflows break in slow motion.
Here s what we saw: Designers spend 80% of their time on technical execution and 20% on creative strategy.
They convert blueprint to 3D manually. They wait days for renders. They lose clients because the approval process feels abstract and scary. The tools they use were built for engineers, not creatives.
We built Foursite because interior designers told us the same thing: their biggest bottleneck wasn t design creativity: it was turning 2D floor plans into visualizations that clients actually understood.
We re not interior designers ourselves. My co-founder and I are engineers who saw a problem and solved it. Convert blueprint to 3D instantly. Show your clients photorealistic renderings instead of sketches. Stop waiting weeks for results.
We re not designers. We re not architects. We re engineers who got obsessed with a very specific problem: why were great interior designers losing clients over miscommunication?
We started building tools to help designers show their vision clearly. Fast. Using AI 3D visualization. And what we built: VirtualSpaces and Foursite solves a problem that s been costing the industry millions in lost projects and damaged relationships.
I m not a designer. I m not an architect. I m a founder who watched talented real estate agents lose deals because they couldn t respond fast enough to client questions about how a space would look.
Six months ago, we launched a simple idea: what if converting a 2D floor plan to 3D took 30 seconds instead of three weeks?
While in the earlier avatar of VR at VirtualSpaces, we discovered a problem: Converting 2D floor plans to 3D visualizations required specialized 3D modeling expertise, expensive software, or outsourcing to teams that took weeks. The handoffs and the lost timelines were crushing practices.
Founder here. Sick of vacant listings dragging 90 days? We were. Built Foursite on VirtualSpaces. Now they sell in 24. 73% faster. Holding costs crushed. My fix: AI visualization.
Drop 2D floor plans. AI converts floor plan to 3D instantly. Blueprint to 3D? Done. No designers waiting weeks. AI virtual staging furnishes photoreal. Upload photos. AI interior design styles it: modern, luxe, cozy.
Here's wishing everyone at ProductHunt a very happy, healthy, wealthy and profitable 2026! May we all win!
We started VirtualSpaces because we believed interior designers were stuck in the wrong era of tools.
They were using workflows designed for the 2000s. Spending 30+ hours on proposals. Waiting days for 3D renders. Dealing with endless revision cycles. Losing projects to faster competition.
We've had an exciting 2025 and are eagerly looking forward to 2026!
We re excited to introduce Remodroom, the newest addition to the VirtualSpaces platform: launching early January 2026. If you ve used Foursite to convert floor plan to 3D visualizations, Remodroom takes a completely different approach to AI interior design: start with a photo instead of a blueprint.
SketchUp has been the workhorse of architectural visualization for 25 years. It's fast, intuitive, and ubiquitous. But it's about to be disrupted, not replaced, but supplemented, by a new category of tools: AI-native 2D-to-3D platforms that make SketchUp look slow.
Here's the numbers: A typical architectural project involves 30-40 hours of SketchUp work - modeling, texturing, lighting, rendering. The results are good. But the time investment is significant.
Now, that same project takes 30-40 minutes with AI 2D-to-3D. The computer reads your 2D floor plan, understands the architecture, generates photorealistic 3D scenes with materials, lighting, and furniture - all automatically.
Real estate development is a game of velocity. Faster time-to-market wins. Better visualization wins. Faster buyer decisions win.For decades, visualization was a bottleneck. Professional rendering took weeks. Revision cycles added more days. By the time the imagery was ready, the market window had often shifted.
AI-powered floor plan to 3D conversion is ending that bottleneck. Instant visualization (tools like Foursite) means weeks of acceleration, which translates to months of economic advantage.
Imagine uploading a 2D floor plan and, in 90 seconds, having a fully furnished, photorealistic 3D environment ready to show clients, investors, or buyers. No specialist needed. No render farm. No weeks of back-and-forth revisions. This isn't science fiction. It's the new standard for how space is communicated - and it's upending every industry that relied on manual visualization.
For real estate professionals: Virtual staging has historically been expensive and cumbersome (rent furniture, coordinate logistics, hire stagers). AI virtual staging flips the equation: $15 - $50 per image, 24-hour turnaround, infinite style variations. Staged homes sell 73% faster. Now every property can be staged, instantly, at scale.
