Here is an interesting idea; why not have your kitchen integrated into the ceiling. This design by David Oelschlägel + Henrike Louisa Binder from Germany utilizes the space above head height as storage.
The bucket lights have been designed to have storage space included, useful for small consumable and non-consumable items that would normally be stored in base units. Once you have finished using the bucket to retrieve the required items you simply pull it down a few centimeters and it goes back up to its original position.
This idea is certainly more concept than mainstream but it does highlight the fact that there is a lot of un-used space above head height, normally allocated for lighting fixtures. In the future, if living space becomes more limited we may have to consider using this space in a transforming fashion in order to make our living environments more comfortable. However, there is also the possibility that doing this will create a claustrophobic environment that will discourage a sense of calm and well being within those who occupy the environment.
