Generally, Berlin has mixed zoning with retail on the street level, apartments above, and offices and small manufacturing in the back. You can't build higher than what you see in the photo (the old limit for fire ladders), unless it's in an area with other higher buildings already. Rents are rising as a return to normal. Most people pay around $1.2/ft^2 (sorry, I have no idea what unit the US uses for rent)
