5. Convert a Garage
If you don’t want to add more room to the house, you can turn your attention to a place you already have, a garage. It would be best to have more work when turning your garage into a kitchen. The first thing is to decide where to install the plumbing, gas pipes, and electric system.
Then replace the garage door and add some windows. The size of your garage and your house design will determine the model and the number of doors and windows you need.  Some people even remove a wall to create an open living area. Choosing kitchen utilities that fit your garage size would be best since you don’t want them to eat up space.
