Central Business District, Amritsar. •Built to open space ratio in the City Centre is 1:5 . •Narrow spaces open into the grand spaces providing hierarchy of spaces and a visual link between two parallel blocks. •The excessive open spaces can be judged by the fact that for 58’ high building nearly 150’-200’ wide streets are provided which open up into piazza of dimension 440’ x 560’. •Open spaces in front of each block links the semi-covered corridors with the outer plaza .

The city centre which once alleged to be the concrete jungle has now boomed with number of shady trees arranged in group or aligned in rows.

Central Business District, Amritsar. • The City Centre which was once alleged to be the concrete jungle has now bloomed with a number of shady trees arranged in groups or aligned in rows. •Interest has been created by creating level differences and by providing small landscaped pockets and water bodies . •There are 3 sculptured fountains in centre ,out of one in front of Neelam Cinema is very popular with the visitor . •This pedestrians paradise scattered with fountain ,sculptures and groves of trees , is blend of cuboids and open spaces . •It is felt that the landscaping features have greatly enhanced the beauty of the centre but the area for soft landscape (water bodies ,fountains) is very small as compared to landscape (concrete paving) these paving in summers radiate a lot of heat creating uncomfortable conditions.

A specialty in area and the centre of attraction is dove of peace sculpture where cascades down from one level to another in geometrically shaped tanks,amidst Dove of Peace delightful play of colourful lights.
