In the case of a housing project consisting of a group of two or more buildings to be constructed on a plot of ground of at least three acres not subdivided into the customary streets and lots which will not be so subdivided or where the existing or contemplated street and lot layout make it impracticable to apply the requirements of this chapter to the individual buildings in such housing projects, the application of such requirements to such housing project shall be made by the city council in a manner that will be in harmony with the character of the neighborhood and will ensure a density of land use no higher than a standard of open space at least as high as required by this chapter in the district in which the proposed project is to be located.
