There are numerous theories regarding the origin of the tube house design, Mai said. For one, the architectural style could have evolved due to expensive land prices.

As the city grew denser, the government imposed tax on the frontage lining the street, leading people to try to reduce the size of the front. But as their families grew, they still needed space — which led them to build inwards and upwards instead, Mai said.

“In the inner city, land is actually gold,” Mai said. “As an indicator of price, the street front is considered as important as land size,” he added.
