any plans for making buildings

does anyone know if there are any plans to for making buildings

Do you mean.. like "blueprints"?
I also tried to find on the Internet, and I was unsuccessful... but the closest thing to a blueprint would be to download a premade-printable building..

there are a bunch of companies selling printable buildings for wargames. And usually they also supply free ones as samples on PDF or JPG format.
