Capsule Hotel design ideas and sketches

Hello, We need your help in creating a design for prototype of sleeping capsules. The same capsules are used in Japanese capsule hotels. But with a new creative design. Right now we need your design ideas as simple sketches, which will be used to create colored sketches/images and 3d models. Method and style of realisation is not crucial. Attached some pictures with aproximative size and form of capsules. It has to be made more attractive: appearance / design / color / change the proportions or offer something competely new, change, add your own improvements, make it more modern / futuristic / attractive. Just some rules: - The external size of capcules has to be 220x120x120cm -Capsuels has to be installed on two levels, so we need the correct way to get into 2nd level capsules. -The capsule should keep the basic internal elements: 3 sockets, holder for water bottle 500 ml, holder for a laptop or tablet PC, the light source. However, their location, shape, color, may vary, you can enhance other minor elements. Also you can add more details and elements (people, objects, etc.) Capsule should give the impression of innovation and futuristics. Upon completion of the work, the client asks for signing the “Transfer of Copyright Ownership” Thanks in advance!
