, Internal Structure & patterns Urban Settlements
● Land use zone = area within urban settlement where one specific function / activity dominates
● Different land use zones form structure of urban settlement
Land use Zones & Urban Profile
● Urban profile = vertical form of urban settlement (Cross-section)
● Most urban profiles have concentration higher-rise building surrounded by lower-rise
buildings that gradually transition into less built-up areas & eventually rural areas
Urban Profile Land Use Zones
Rural-urban fringe
● Business centres with gardens &
parking
● Located in residential areas/ on outskirts
of urban areas
● Can be office complexes / mixed business
venture
● Built around garden & attractive, become
popular
● Business moving away CBD & offers
opportunity former city office block
converted into residential units
