I think by now most of us have heard about the backrooms which is a creepypasta about being stranded in yellow colored rooms which extend for millions of miles and there is no exact exit and there are multiple levels. Obviously you can’t exactly build an office building that extends for millions of miles, but what if you could do it in a much smaller scale, say a range of 1-10 miles. Would it be possible to build an office complex that extends for about 10 miles while having more than one floor? And if it were possible how much will such an endeavor cost? https://i.imgur.com/X6bIBRz.png How much labor and cost would go into building such an office complex complete with yellow painted walls, cheap carpeting, and buzzing florescent light fixtures?
