No.1 Architects plan estates that can vanquish racism

The world’s leading architects will meet in London on Tuesday to launch plans for Britain’s housing estates of the future – estates that will help to combat racism.

Following the failure of concrete urban complexes, tower blocks and far-flung suburban cul-de-sac developments, internationally acclaimed architects, including Daniel Libeskind, who will rebuild Group Zero in New York, and Britain’s Richard Rogers, Zaha Hadid and Will Alsop are to support a call for a return to old-fashioned terraces and mixed community living.

Alsop Architects is to urge town planners and housing associations to reconsider the shape of the conversional two-up, two-down terraced house. Partners believe that, far from alienating residents, such affordable living can promote a sense of belonging and prove less socially divisive.

“Mistakes were made in the past, but architects generally are a lot more savvy now about what will and will not work,” said James Hulme of Alsop Architects.

Tom Bloxham, chairman of the Urban Splash Group, is working with Alsop Architects on urban renewal work in Manchester and also on a project in Salford where unwanted two-up, two-down terraces are being restored.

“There has been a false divide between social and private housing and it has the effect of social engineering,” he said. “People given the highest number of housing points by the local authority, the people with problems, get put together. So estates become ghettos and neighboring gated ghettos for the rich also develop.”

The conference will focus on radical ways of integrating black and ethnic minority communities. The Housing Corporation which is responsible for investing more than $2 billion in social housing and housing associations, tries to ensure that people want, and can afford, to live in the homes that are available.

“Black and minority ethnic communities have in the main been dealt a poor hand when it comes to social housing,” said Baroness Brenda Dean, chairman of the corporation. “But innovative design should not be the sole domain of the private sector and we are challenging the architectural community to drive a sea change.

The summary I wrote is following:

The new housing estates of the future which will help to reduce racism will be discussed by the world’s leading architects in London who believed to rebuild the old-fashion terraces and mixed community because of the failure concrete urban complexes. The Alsop Architects prompt the modal of two up, two-down terraced house in order to correct the misunderstanding and improve the neighboring communication further more. By mainly solving the racial problems of the black and ethnic minority, much more investment will set up in this project. of course, except this proposal, others actions to remove the racism play more important role

(这一句可以改成主动式）The Alsop Architects prompt the modal of two up, two-down terraced house in order to correct the misunderstanding and improve the neighboring communication （去掉further more,因为improve的意思与这个重复）. By mainly solving the racial problems of the black and ethnic minority, much more investment （这个是主语吗？不对吧）will set up in this project. of course, except this proposal, other actions to remove the racism play more important role
