You should use the full scale. And, there isn't a limitation for Reynold's Number but there is a limitation in regards to turbulence modeling. There are three categories for turbulence modeling, RANS, LES (or DES), and DNS. You will not have enough CPU power to do DNS. LES might be possible for you, but it is very expensive. Unfortunately, depending on how accurate you would like your results to be (i.e. qualitative vs. quantitative), RANS does poorly on base drag and areas of large separation, as you would experience with a building. A RANS calculation can be off on base drag/pressure by 30-40 percent at high Reynolds number. You should investigate literature to find problems similar to yours.
