Scaling up a printer involves much more costly components and care, because of the need for:
- increased rigidity
- more powerful motors and more sophisticated motor drivers
- closed loop
- a faster controller (32-bit)
- longer cable runs for sensors and motors
- changes to extrusion for increased output and pressure management
Do you have funding?
Plus for this project you will need more sophisticated/different and therefore custom slicing software.
I think developing this is a full time job for at least 5 individuals (programmer, materials scientist/test engineer, electrical/CNC engineer, structural engineer, machinist).
Just getting the extruder right will be a big challenge.
I think getting the outside smooth (like Contour Crafting is beginning to do is important), not just for looks but for structural integrity, water-tightness, and maintainability. I've seen other videos where a deployable smoothing blade was used.
In one video I see walls made with a zigzag inner core - but are the zig-zags actually bonded to the outside walls? Since concrete has little "pull" strength, will these hold? Can fiber be used to strengthen these walls? Making sure the structure is actually strong (and won't crumble in an earthquake) is critical. These are some questions you will need to answer before governments will approve this build technique.
You haven't mentioned the reason for this pursuit - Educational? Philanthropic (houses for the poor, etc...). Commercial?
Since you are starting from zero, I'd recommend visiting the various teams that have been working on this for a while, and collaborating. Hopefully there are not yet patents that will cause problems...

Software: What are you basing that off of?
