A kitchen with an island requires lots of attention from a planning point of view.
If possible, it is best to define the position of each single element and their sizes in the planning phase of the kitchen.
The architectural drawing in its top and front view must include the measurements of the furniture, of the walls and of the aeration holes that must be precise to the centimeter.
If the project of the building allows for it, it is a good idea to plan for the hood fumes outlet in the ceiling, above the hob.
The co-ordinates of the ceiling fumes outlet centerline must be calculated in the following way:
- crosswise, add to the distance of the island from the wall (X), a distance (J) that will vary depending on the type of hood (J is equal to 35cm for the most common types of hood).
- lengthwise, add to the distance of the island from the wall (Y), the distance to the hob centerline (K). This way it will be possible to fit the hood flue perpendicularly to the ceiling without the need for curved pipes that are often concealed by unisghtly false walls.
The island requires a working space of about 120 cm. This is the optimal space necessary to simultaneoulsy and comfortably open the doors of the island and of any tower units installed along the wall. (In any case, the minimum space required for working is 100 cm).
To calculate the distance of the island from the wall it is necessary to add 120 cm to the depth of any elements installed against the wall (wall panels, towers or worktops).
For good hood extraction, the flue outlet must have a diameter of at least 15 cm.

If possible, to minimise the impact of the motor noise, it is preferable to choose a hood with a motor that can be installed outside the kitchen.

For an excellent aesthetic result, consider the possibility of arranging the kitchen elements in an aligned and symmetric way.
