I am in beginning stages of diy renovation of a rundown double wide mobile home.

52′ x 28′ . the midline where they meet is 13.5′ for each side.

I was wondering where i could go to get a better floor plan that is more energy
efficient. I believe that i can move things around. the limiting factor is the
walls in certain sections needed to support the roof.

Any advice on who I can contact ?

Would it be an architect ?

Thanks for any help.!!
