Next, the film moves on to explain the borough's housing problem; back-to-back tenements are shown with children playing outside. This is illustrated by a panning shot over some of the decrepit and crumbling housing stock. Builders are seen demolishing walls (they are lightly attired with no protective clothing, using their brute strength to push the walls over and large clouds of dust result). The solution to this housing crisis is to build workers' cottages: there is a sweeping pan of houses under construction. The final result is very pleasing; low-rise, airy housing with large windows. There are point-of-view shots along a typical street with young trees planted along the road. The council achieves its work by having a Works Dept and employing men directly; men are seen in a workshop, two are maintaining a car, others are digging in the road. This department was also responsible for refuse collection (a significant problem only tackled unilaterally in London by the formation of the Greater London Authority in 1963). Over half way into the film, the responsibilities of the Public Health Department are outlined; apparently the death rate had been reduced from 21 people per 1000 to 13 in the 30 years prior to the film being made (a 38% drop). This had been achieved by tackling infectious diseases; a bacteriological laboratory is seen with the technician peering down a microscope. The disinfection station is seen where bedding and other bolts of bedding and fabric are steam cleaned for 30 minutes (to kill parasites).
