Here is a wall mounted computer/laptop desk that collapses to about one inch thickness to take very little room and offer great utility.
In a Tiny House Kitchen space will be of the essence. Still, it would be nice to have some of the amenities of a larger kitchen such as a prep island table. There are designs that offer that and can serve as a storage cabinet/pantry/utensil storage, and a dining table. As this device is mounted on casters that swivel, it is easily moved about to provide space as needed.
This island below is set up to store four dining chairs. If shelves are built in the cabinet, it can provide room for canned food goods or cooking utensils all while requiring very little space..
The kitchen of any home is of primary concern. Stoves & Refrigerators can take a lot of room even if they are apartment sized. It may be possible to look at these items as mobile units (which are available) so they can be moved easily to adjust the room in the kitchen or even transport to an event like a tail gate party at a game.
Here is an example of a cooking stove for campers that may cover the needs of a Tiny Home. It could be moved to the porch or deck for outdoor cooking along with a small refrigerator. It's shown with a BBQ Grill propane tank but smaller tanks are available.
A seven or eight cubic ft Refrigerator may be all that is needed for a Tiny Home kitchen to furnish it. Small enough a young woman could move it about if necessary. There would be a freezer area on the top of the unit
For the living room a comfortable chair would be a center piece. Often a recliner is desired. But there are "recliner" chairs which can nearly become a bed.
There are fold out arm mounted wing tables that can be attached to an easy chair too. It adds extra usability to the chair.
