Exclusive plot of land of 998 square meters with high density residential and comercial zoning (RM3C2).
Given the location in my opinion pretty much any comercial development to include: mixed residential with ground floor comercial or just comercial space or mixed comercial and office, boutique hotels, mini mall, etc. could work fine however I think a small hotel with a nice family orientated restaurant in the ground level together maybe with a coffee shop with good parking (very important for the area), would work wonders.
There is nothing like been certain of a good location and in this case 50th street is home to the most imposing comercial Towers in this country. Additionally we can also say that it is surrounded by five star hotels, two blocks from Ave Balboa puts you within minutes from the most developed residential building areas of the city. (meaning 40 floors or higher)
Plans of a 17 floors of comercial mixed with office space can be sent via email for the purpose of obtaining an idea of what can be done according to the size of the plot of land.
