The traditional sink–refrigerator–range triangle remains useful as a conflict check, but many kitchens need a broader zone model.

Keep the triangle as a diagnostic
Long detours, an island blocking a route or a doorway cutting through the triangle can indicate poor placement. The triangle does not specify all the landing, storage and multi-cook needs of a modern room.
Build zones around complete tasks
- Preparation: knives, boards, bowls, ingredients and waste.
- Cooking: range, ovens, utensils, oils and heat-safe landing space.
- Cleanup: sink, dishwasher, waste, towels and dish storage.
- Breakfast and beverage: coffee, kettle, mugs and common supplies.
- Serving: dishes, cutlery and access to dining.
Avoid duplicate congestion
Two sinks or two ovens do not improve workflow when their doors and users occupy the same narrow aisle. Place secondary zones only where the room can support them.
Plan for the people who use it
A one-cook apartment and a multigenerational household need different storage heights, clearances and circulation. Use generic planning rules as a starting point, then test real routines.
