I don't hink that Building 16 is part of the business center. https://www.mapillary.com/app/?pKey=914554986265073

I have already delivered here and some office (Lire et écrire; TonTon Chami) are on the left after the gate (+- where 14 is set). There is also Parking brussels more on the back (near CEMEA but don't know the exact location).
