For the past eight years, my workflow looked like this: AutoCAD for plans → SketchUp for modeling → Lumion or Enscape for renders → back to AutoCAD for construction docs. Five programs, endless exports, and constant crashes on my aging laptop.
Then I kept seeing jaw-dropping renders on r/InteriorDesign credited to something called Coohom — all made in under an hour, on a web browser. I called bullshit… until I tried it.
This is the real case study of what happened when I locked myself into using **only Coohom** for an entire month on actual client projects.
Day 1 – Zero Downloads, Instant Regret (The Good Kind)
Opened Coohom.com, signed up with Google, and was drawing walls 40 seconds later. No install. No “waiting for V-Ray to update.” My 2020 laptop with integrated graphics didn’t even break a sweat. That alone felt like cheating.
Week 1 – A Full 72 m² Apartment, Done in 38 Minutes
Real client project:
- Drew walls with perfect snapping and thickness controls
- Dropped doors/windows straight from the library
- Hit the AI Decorator → chose “Scandinavian Warm” → watched Coohom auto-furnish the entire living room in 8 seconds
- Minor tweaks and it was done
From blank canvas to fully furnished 3D model: 38 minutes flat.
Week 2 – The Render That Closed the Deal Instantly
Client wanted “something emotional.” Used Coohom’s Smart Angle (it suggests the eight best camera angles automatically), switched to golden-hour lighting, and hit render.
4K photorealistic image → 47 seconds later → sent on WhatsApp → client literally cried happy tears and paid the deposit that same afternoon.
Week 3 – Construction Drawings & BOQ That Contractors Actually Love
One click → fully dimensioned plans, elevations, sections, and a complete bill of quantities. Exported clean PDFs in under two minutes. My contractor texted: “Finally, drawings I don’t have to redraw.”
Week 4 – Real-Time Collaboration + Cinematic Walkthrough
Invited a freelance collaborator in another country. We edited the same file simultaneously — like Google Docs, but for 3D interiors. For the final presentation, I dropped the model into one of Coohom’s animation templates and exported a 45-second cinematic video in 12 minutes total.
The Hard Numbers After 30 Days
- Projects finished: 4 (normally 2)
- Average concept-to-client-ready time: 3.5 hours (vs 3–4 days before)
- Money saved on external rendering: ~$280
- New inquiries from posting renders online: 3 direct clients
The Few Real Downsides
- Free plan caps renders at 1080p and limits exports — upgraded to Pro on day 9 (100 % worth it for paid work)
- Ultra-complex parametric stuff still starts in Rhino for me, but that’s maybe 3 % of projects
Final Takeaway
If you’re an architect or interior designer who’s tired of living in six different programs, Coohom is the first all-in-one web platform that actually feels like the future instead of a compromise.
Try it yourself — the free plan is legitimately powerful and will probably ruin your old workflow forever: Coohom
