Design for a micro-small outdoor office

Hi - I would like some design options for a small outdoor room/studio/office that will be placed in a small courtyard. The design needs to suit the following basic dimensions: 180mm wide 150mm deep 220mm high Also, the room needs to be built on-top of the ground, so the design requires a self-standing construction. Photos of the courtyard will be provided to the successful freelancer. The job requires images of the proposed design to be provided, and as a possible next-phase (which will be negotiated separately) detailed designs including measurements that could be passed to a builder/carpenter for construction. Good luck!
