Answer the following question: Read the following paragraph and extract the answer for the question: What is the name of the neighborhood that is now upscale and a shopping district?  Efforts began shortly after the explosion to clear debris, repair buildings, and establish temporary housing for survivors left homeless by the explosion. By late January 1918, around 5,000 were still without shelter. A reconstruction committee under Colonel Robert Low constructed 832 new housing units, which were furnished by the Massachusetts-Halifax Relief Fund.Partial train service resumed from a temporary rail terminal in the city's South End on 7 December. Full service resumed on 9 December when tracks were cleared and the North Street Station reopened. The Canadian Government Railways created a special unit to clear and repair railway yards as well as rebuild railway piers and the Naval Dockyard. Most piers returned to operation by late December and were repaired by January. The North End Halifax neighbourhood of Richmond bore the brunt of the explosion. In 1917, Richmond was considered a working-class neighbourhood and had few paved roads. After the explosion, the Halifax Relief Commission approached the reconstruction of Richmond as an opportunity to improve and modernize the city's North End. English town planner Thomas Adams and Montreal architectural firm Ross and Macdonald were recruited to design a new housing plan for Richmond. Adams, inspired by the Victorian garden city movement, aimed to provide public access to green spaces and to create a low-rise, low-density and multifunctional urban neighbourhood. The planners designed 326 large homes that each faced a tree-lined, paved boulevard. They specified that the homes be built with a new and innovative fireproof material, blocks of compressed cement called Hydrostone. The first of these homes was occupied by March 1919. Once finished, the Hydrostone neighbourhood consisted of homes, businesses and parks, which helped create a new sense of community in the North End of Halifax. It has now become an upscale neighbourhood and shopping district. In contrast, the equally poor and underdeveloped area of Africville was not included in reconstruction...

Hydrostone
