Multiple Nuclei Model
• Distinctive land-use zones develop because some activities repel each other
• high-quality housing does not generally arise next to industrial areas
• other activities cannot afford the high costs of the most desirable locations.

• New industrial areas develop in suburban locations since they require easy access
• outlying business districts may develop for the same reason.
• Transportation improvements allowed for deconcentration

• Some cities or conurbations have engulfed surrounding settlements or have evolved strong suburban areas around the periphery of the city.
• Both of these situations cause the 'suburbs' to function as small independent business districts with their own shops and businesses away from the main urban center.

Key factors leading to a multi nuclei model:
• need for increased accessibility to a center (not necessarily the CBD)
• to keep conflicting or competing land uses apart (eg. high cost housing and smoky factories)
• decentralization
• differences in land values

Examples of nodes (nuclei)
• An airport will attract hotels and warehouses to store items to be shipped by plane.
• A big mall will attract apartments and smaller strip malls.
• A college will attract bookstores and pizza restaurants.
• A middle class residential area will attract supermarkets.
