Alsop Architects has unveiled its masterplan for Bradford, which includes the creation of a city-centre urban park surrounding a new lake in front of City Hall.
The scheme - commissioned by Bradford Centre Regeneration - aims to differentiate the city from other towns in the north of England and provide a trigger for inward investment.
The creation of the urban park will 'expose many of the gems of Bradford's Victorian architectural heritage', including its Wool Exchange, St George's Hall, the Alhambra, St Peter's House and the cathedral.
Based on Bradford's distinctive topography, the plan also envisages the development of four new neighbourhoods, focusing on exhibition centres and retail activities, as well as areas of new wetland.
The practice believes demolition of the low-value buildings and housing in the city centre - essential for the new lake and parkland - will also encourage regeneration by reducing oversupply and forcing up prices.
Bradford Centre Regeneration chief executive Maud Marshall said Alsop's plans gave the town a real opportunity.
'This is a fantastic, once-in-alifetime opportunity to put an end to decades of decline and to significantly improve the built environment, ' she said.
