Greenfield sites:Areas on the edge of
the city which have never been developed in any way. These provide cheap,
unpolluted land, with room for expansion.
Greenbelt: The green belt project in
Barcelona aims at creating a continuous network of agricultural land and
woodland around the city where development is controlled. The main aim is to
prevent urban sprawl.
Change at the city edge
Car scrap-yards, fields of caravans, car-racing circuits, petrol stations,
amusement parks, prisons, teleports, campsites, hotel complexes, golf courses,
integrated goods-transport depots, water treatment plants, dumps, all go to make
up today's chaotic metropolitan landscape. It is virtually impossible to
distinguish between the urban and the rural (or non-urbanisable) land (both
visually and legally).
Growth of suburbs, e.g. Sant Just Desvern.
Mature families move for improved housing and a higher quality of life
New shopping malls: e.g. Gran Via 2, taking advantage of an increasing
Airport expansion: to cater for increase in flights, particularly for
High-speed rail link to improve infrastructure

New university and business park (Viladecans
New industrial estates e.g. Sant Boi, Castelldefels
