The maps compare a town called Langley in 1910 and changes it went through until 1950. Overall, the town used to be more of an industrial site in 1910 with a substantial wasteland, but within 40 years it had become a developed city with more residential, recreational facilities.
In 1910, the town had two streets that were not connected: Jordan Street that crosses the city vertically, and Sherman street in the horizontal direction. Both streets had a row of houses with parallel bushes at both sides. In addition, there used to be a railway line alongside the southern edge, with a row of cottages allocated for railway employees.
Another major feature in 1910 was the factory located to the north with two wastelands in the north-east corner and to the left of the cottages. The only facilities available for the residents were a store, a laundry, and a cafe, all concentrated to the east of Langley.
The years until 1950 had experienced major changes in terms of infrastructure. For instance, the two streets were connected, which was made possible by the demolition of the houses on Sherman Street and the ones to the right-hand side of Jordan Street. While the railway line and the cottages also disappeared, a new side street called New Lane that branches off from Sherman Street toward south had been constructed.
The town experienced major changes in terms of facilities, too. The most significant change was in residential blocks. Across the left of Jordan Street a line of high-rise flats appeared, as well as three mansions to the north of Sherman Street.
The southern wasteland had been removed to make way for Sherman park that houses trees, a pond and a playground for children. The laundry and the store had been moved to the site that was previously the wasteland to the north-east. Finally, instead of the store next to the laundry in 1910, there was a row of three stores to the right of New Lane in 1950.
