Band 9: The two maps below show a housing estate now, and how it will look after redevelopment. Provide an overview of the information by identifying and describing the key details, and include comparisons where appropriate.

The maps show the current layout of a housing estate and its proposed redevelopment.

Overall, the area is expected to undergo a significant reorganization, with much of the greenery removed to make way for recreational facilities. Notably, all four-bedroom houses will be replaced by smaller ones, along with improved road access.

At present, the estate mainly consists of scattered four-bedroom houses surrounded by large areas of greenery. A main road lies to the north of the estate, from which a private road runs into the center before looping back and reconnecting, forming a U-shape.

Following the redevelopment, one-, two- and three-bedroom houses will replace the existing four-bedroom ones, all of which will be arranged more densely in the center of the area around a new flower garden. This new organization, however, will come at the expense of much of the greenery.

Of the new facilities, a car park is expected to be built in the southernmost part of the estate, whereas a man-made lake and a tennis court are to be constructed in the northwestern and northeastern areas respectively. Road access, meanwhile, will be improved significantly, extending into the center while retaining its original U-shaped layout.
