I'm in the market to buy a 3D printer for our company so we

I am quite certain that as a single print this is almost impossible to print at the scale you are discussing. even on allot of the high end printers.

if your smallest structural member is a 50mm x 100mm (2"x4") you will be unable to print this structure at a scale smaller than 1/50, 1/25 would be more reasonable. at 1/50 scale a 200x200 mm printer would only do a structure who’s real life scale is 9.5 m on edge (save some size for skirting). This is not really useful for you.

If you print the 50mm x 100mm (2"x4") based walls as a solid wall 125mm (~5") thick it would probably no longer be your thinnest member, then i am assuming your thinnest member would be 100mm x 100mm boards At that size you could go down to 1/100 scale, (still realistically 1/50 would be an easier print). Then you reach the 95 m scale. That would begin to be useful for a structure this size.

Remember you could print some sections with solid walls or no walls, in a small scale and then the more important section in larger scale… but realistically you will not be able to push beyond a 1mm thin structural member on high end printers at this point.

Ok

DLP or SLA is your best bet as mentioned before:) would be awesome to see if this turned out well!

Good luck removing support material if printed in SLA or DLP. SLS shake the part and walk away! You would need to slice into manageable sections so the minimum wall thickness is around 1mm

True that’s ofcourse the biggest issue. how long can SLA or DLP bridges be? approximately. if 5mm or more the issue would be nonexistent for internal structures at that scale
