As the 19th century gave way to the 20th, Woodside's plentiful advantages convinced real estate developers to invest substantially in high-occupancy housing and duplex homes to complement the single-family units which had dominated the area. Three representative examples are Woodside Apartments built in 1913, the Metropolitan Life Insurance Company's project of 1922, and the projects of the Woodside Development Corporation in 1923. Located near the rail and rapid transit stations, the Woodside Apartments was a row of four-story, semi-detached buildings. There were four apartments on a floor, most of them having four rooms. Rents initially ranged from $18 to $20 a month. Located just as close to the trains, but on the other side of the village, the Metropolitan Life apartment project was more ambitious. Consisting of ten five-story buildings, the project had space for four hundred families. The Woodside Development Corporation built four-story apartments with stores on the ground floor and both two- and one-family houses on two large plots of land near the center of the village. When a citywide aerial survey was taken in 1924, Woodside was shown to have quite a few other multifamily apartment buildings and duplexes along with its many small single-family homes.
