Safety First! You are better off without it if you are using up all the free space in the room. Your kitchen should be spacious and you should never feel restricted in your movement - in fact it can be dangerous if you are. Yes, a kitchen island is good to have, but not if your safety and freedom of movement are compromised to accommodate it.
Budget : Setting a budget out front can be beneficial if you have budget constraints. Having a budget to work on, you can easily adjust the types of material to be used or length of wooden planks to be purchased accordingly before ordering the materials.
The dimensions and placement of your kitchen island will depend on the shape and space available in your kitchen. Professionals say that the island should be positioned at least 36" from existing cabinets and 42" from the range, refrigerator or dishwasher to allow plenty of room for opening doors and easy maneuvering around your workspace area. The height of your kitchen island can vary to suit your individual needs. If you can't make up your mind on that one, a multi-level island might be the solution.
If you have a big island that can accommodate many people, consider using full benches. The benches can be with or without backing to allow for more comfortable seating.
