>>7614284This wasn't particularly expensive it's one of the new 99$ space base sets expanded with 20 white wall panels fron a pick a brick cup, nine windows from the hall of armor and then just random computers up top. I had no idea I had so many white window frames but I'd imagine they're cheap on bricklink. Had I bought all this from Bricklink instead of Lego it'd have cost 60~80$ vs the 170$ Lego sticker price I paid for the two sets white joining bricks and handfull of blue 1x6's to make the hanger doors taller
