An island is on many wish lists, but it only works if the room is big enough. Done well it adds worktop, storage and a place to sit. Done badly it blocks the kitchen.
Check you have room
You need clear space all around the island to walk and open appliances. As a rule of thumb, allow enough for two people to pass, and check the clearances recommended by your kitchen designer. If the room is tight, consider a peninsula or a slim worktop instead.
Decide what it should do
- Extra worktop for preparing food.
- Seating for breakfast or homework.
- Storage in drawers and cupboards.
- A sink or a hob, if the services can be moved there.
Seating
Leave enough knee space under the overhang and choose stools that tuck neatly under. Think about whether people sitting will be in the way of the cook.
Sinks and hobs on islands
Putting a sink or hob in an island means new pipes, waste and wiring across the floor, and a hob needs extraction. These need qualified professionals, and are a bigger job than a plain island.
Materials and finish
Choose a worktop that matches or complements the rest of the kitchen. A contrasting colour on the island can make it a feature.
Lighting and sockets
Pendant lights above give task light and character. Plan sockets for the island early, because they are hard to add later.
Alternatives
- A peninsula, attached to a wall, uses less space.
- A freestanding table or butcher's block is flexible.
- A slim breakfast bar along a wall.
