The bar chart compares the number of houses built in four categories—detached houses, semi-detached houses, terrace houses, and flats—across four years from 1999 to 2002.
It is clear that detached houses were the most commonly built type of house throughout the entire period, while flats had the lowest construction numbers in 1999 and 2002. Detached houses and terrace houses saw a general increase in the number of units built, whereas semi-detached houses and flats experienced a decline over the years.
In 1999, the construction of detached houses started at just over 1700 units, and this steadily increased each year, reaching a peak of around 2200 units by 2002. This upward trend shows a consistent demand for detached houses throughout the four years. Conversely, terrace houses, despite being the least common type of house, saw a modest rise in construction numbers, from just under 1000 units in 1999 to approximately 1300 units by 2002.
The number of semi-detached houses, on the other hand, followed a downward trend. Starting at about 1700 units in 1999, the figure dropped significantly to just above 1000 by 2002. Flats also experienced a noticeable decline, with the number of new units built falling from 1500 in 1999 to around 900 by 2002, with a slight increase in 2001.
