Small spaces-need help Stuck in a corner

My husband & I live in a efficiency (house) with only bathroom separated.What i have is a house built like an efficiency apartment, but its a house. We are so cramped and have little storage. I need advice on how to determine what is right for the room and the kind of storage I can build for such a small space. I already got rid of our dresser and put our clothes in plastic containers under our bed. I want to build stuff that can give me more floor space.

Any and all ideas are much needed. Stuck in a corner.

Thank you JoAnna
