A dream of an architect of 25 years old.

I have been an architect for 3 years, I have worked in several design offices, and I have done a lot of site working, like monitoring sites than I was the project manager of, for example a 240-bed hospital. At the office I do all the graphics files [facade?] and sectional plan projects as well as 3 dimentional plans.
I need to improuve my english for working with international enterprise.

This is really good. I hope my corrections make sense with what you were trying to say. :)
