Design like a full-suite team from day one.
Rubber Duck brings building systems intelligence into your earliest design — so spatial conflicts surface while they're still simple to solve.
HVAC needs real space — but it's planned after the big decisions.
HVAC systems claim shafts, plenums and mech rooms. When engineers engage late, the architect has already committed the massing — and resolving a conflict means redrawing what's done.
Full-suite spatial awareness, from the first sketch.
Early & flexible
Works with schematic boxes, 2D or 3D, inside the tools you already design in.
Focused on what matters
Surfaces spatial requirements for high-impact elements — shafts, plenums, mech rooms and zoning conflicts.
Multi-objective control
Front-loads the trade-offs between competing goals, so costly late-stage changes simply don't happen.
From flying blind to a full team in the loop.
- 17× weekly coordination meetings
- ↻ tedious late-stage redesign
- ⏳ delayed or withheld MEP insight
- 3× focused reviews
- ✓ issues avoided early & easily
- ◆ fast and cheap trials & errors, 24/7
One duck today. A full flock tomorrow.
Rubber Duck starts with HVAC — the most spatial, highest-impact building system. Each agent that follows adds another specialist to your day-one team.





Speeding up the world's slowest, most vital industry.
To serve more people, faster — by giving everyone who shapes a building the full picture from the very start.
