2 storey addition

I'm looking to build a 2 storey addition on my property. The purpose of this addition is to provide additional living space for my growing family. I'm aiming for a traditional architectural style to ensure that the new addition blends in with the existing structure of my home. I don't have any plans or permits for the project yet as I need help with this aspect. I'm hoping to find a reliable and experienced freelancer to take on this project who can help me to draw up plans and get the necessary permits.
