Carl:
Sorry, that project is not resizable using the CHBD. There are a couple of reasons why…
1. It’s designed to utilize mostly 8 foot lumber.
2. The standard size is stable, making it smaller would make it unstable, unless very well anchored.
3. Making it much larger exceeds the scope of the intended plan.
4. It’s a structure, not a bar per se.
5. CHBD was meant for just bar sizes, not structures with roofs.
6. CHBD READY plan sets show a little icon on the plan over pages that indicates if it is resizable or not.
The CHBD is intended for making nominal changes to select bar designs for fitting purposes only. These changes can facilitate some very interesting configurations nonetheless. Manual changes to the EHBP-20 are possible. You can substitute a hip roof but the design work the gets more detailed.
I think there is a forum topic for modifying it to a hip roof rather than a gable design.
