BIM for small & mid-size builders
Plan in 3D before you build on site.
From 2D drawings to 3D dreams.
We turn your PDF drawings into a coordinated 3D model with clash detection and a generated bill of materials, so you can avoid costly surprises, delays, and rework.
Send us your architectural and structural PDFs — get results back in a few days.
Typical project
Custom house + laneway
3D framing, HVAC & sprinkler routing, clash detection, and material take-offs delivered as a clear, visual package any trade can understand.
How 23D works
Simple workflow designed for busy builders and project managers.
Send us your drawings
Email us PDF drawings of your architectural and structural sets. Mechanical and sprinkler drawings are optional but recommended for full coordination.
- Architectural PDFs
- Structural PDFs
- Optional: mechanical / sprinkler
We build the 3D model
We create a coordinated 3D model of framing, structure and key building systems. Our automation accelerates modeling while still allowing manual checks where it matters.
Think of it as a “digital dry-run” of your build, before a single stick is cut on site.
You get clear deliverables
Within a few days, you receive:
- 3D model exports for review
- Clash detection report with screenshots and notes
- Generated bill of materials for framing and key elements
Explore a live 3D model
This is a real 23D coordination model embedded from Speckle. Pan, orbit, and zoom to see how we visualize structure and systems before construction.
Why builders use 23D
We focus on problems that actually cost you money on site.
1. Eliminate costly on-site errors
Uncoordinated plans from different consultants create clashes that only show up once you’re framing. That leads to emergency RFIs, change orders and delays.
Our clash detection finds these conflicts in the 3D model before construction, so issues are solved on paper, not on site.
2. Achieve budget certainty & reduce waste
Inaccurate material take-offs drive budget overruns and piles of unused lumber on site.
Our 3D model generates an automated bill of materials, giving you a solid baseline for ordering and reducing waste.
3. Streamline construction & reduce delays
Ambiguous 2D plans slow down trades and create arguments in the field.
Clear, unambiguous 3D views and optimized routing make it obvious what needs to happen, so crews can keep moving.
4. Access powerful tech at an unbeatable price
Traditional BIM software is expensive and requires specialist staff, which is out of reach for many smaller builders.
Our automation-driven workflow and AI-assisted tools make “digital twin” style planning accessible to regular residential builders.
5. Maximize headroom & protect structure
Poorly coordinated HVAC and sprinkler lines lead to ugly bulkheads and unnecessary holes in structural members.
By modeling these systems in 3D, we plan routing that eliminates bulkheads where possible and avoids risky structural penetrations.
Case study: main house + laneway
A real project where 3D coordination caught issues that 2D plans missed.
What we found
- Conflicting headers above a large north sliding door and window.
- Stair beams intersecting with stair runs between first and second floors.
- Exterior walls without proper supporting beams under roof decks.
- Beam height differences causing inconsistent wall heights in balcony and interior areas.
- Roof beams conflicting with flat roof and stair enclosure geometry.
Why it matters
These are the kinds of issues that usually show up only when you’re mid-framing, with trades on site and schedules already tight.
By surfacing them early in a 3D model, the builder was able to coordinate fixes with the designer and engineer in advance, avoiding:
- On-site redesigns
- Last-minute RFIs and change orders
- Delays cascading into following trades
The result: smoother framing, fewer surprises, and a cleaner final build.
Is 23D a fit for your projects?
Designed for small and mid-size residential builders and developers.
Custom home builders
Single family homes, spec builds, and laneway houses where every change order and delay hits your own bottom line.
Multiplex & infill developers
Urban infill, multiplex, and small multi-unit sites where tight footprints make coordination and headroom critical.
Construction managers
Owners’ reps and CMs who want a clear, visual coordination tool to align designers, trades, and clients before construction.
Pricing depends on project size and scope, but our goal is simple: deliver the benefits of BIM without “enterprise BIM pricing”.
