This is a design for a standard kitchen that has an island that is sligthly higher than the other parts. It has 3 chairs. One for you and two for the grandchildren ( assuming two is the standard number ).
Most important part. Since you are always on the move and can not cook too much this is an excellent kitchen for that. Simple and small yet enough for you and your needs. You can put the grocerries on the island table and leave them there.
Also much more important is when the kids come to visit they can do their homework on the islnad table while you bake cookies! Meaning that they will always be near you while visiting. There is space for two kids to do their homework together on that island table.
The bathroom is in the shape of a line as to be standard so you can use this design almost certainly. The fixtures are also there. The flooring and colour are also in the project.
Enjoy.
