I am a recent Product Design graduate and this was my final year project.
Feel free to ask me questions about it and I will to answer them as quickly as possible.
The main idea is that it is stored an hidden alongside toher kitchen cupboards then can be accessed by pulling down to the user. The weight is taken by a system similar to on the boot/trunk of a car and the shelves stay level with a gear and chain mechanism.

Thank you for any feedback/constructive criticism.
