Foundation Architecture and Design
Draw, draw, draw. Set yourself the goal of doing at least 30 minutes to 1 hour of sketching every day. Remember to always draw from life, and not photographs.
Keep an eye out for contemporary designs or projects that have just been completed, things that are trending currently; Archdaily is a great source.
Why not set yourself a design project to re-design a garden office room in your house, like your bedroom?
