I agree with what Vandana said in her answer, you can go to a college and get a degree in Architecture. The schooling is your best path forward and a great place to start.
Also you can try to find a job as an intern at an existing engineering firm, this will allow you to learn on the job while completing the required schooling. A mix of field and school in my humble opinion is the best way to be well rounded in your field.
Best of Luck.
