This corner of a client's tiny kitchen had huge storage potential. After taking measurements I made my suggestions (I hand draw everything, I'm not so keen on computer sketches).
The basic idea was to put a tall skinny cabinet in the corner then add shelves (attached to the corner unit) in front of the window for prep surface with room below for recycling + garbage. The window is never opened but suggested the shelves be on a hinge so they can be lifted for access to the window in case of emergency.
They ended up going with a modified version of option #1, just adding the tall open shelf unit. They figured they'd start with the shelf unit and add to it later if needed.
