You Designed It Right.
Let’s Make Sure It’s Built That Way.
Every drawing, every detail, every decision—protected.
Make your intent visible. Keep your vision intact.
Not a design issue. A delivery issue.
You made the right call.
But someone didn’t see the markup.
Didn’t read the comment.
Didn’t open the right file.
The result? Wrong thing built. Again.
“Architects shouldn’t be file managers. You deserve tools that carry your clarity.”
We’ve been there. That’s why we built this.
Meet Ponk, HTCH founder.
Ponk worked as an architect for over 10 years.
We’re architects too. We know what it’s like to obsess over details—only to see them missed during construction.
We built HTCH (“hatch”) to protect that work.
Now, teams across UK and Southeast Asia rely on us to deliver clarity from first sketch to final handover.
Here’s how it works:
1. Upload your files—PDFs, images, 3D models
2. Mark up and comment directly on them
3. Share with your team—no training needed
Your clarity. Delivered.
