32x32 base plate

Jrdavisok

I am looking for a part #for a 32x32 plate. I I need to make a 2nd story so it needs to be able to snap together on both sides. I have the flatter base plates for first floor already. Or some key word that identifies it as such. Please help

There is no such plate, based on color or price, I would use 4 of 16x16 or 8 of 8x16
