Topic: Describe your detail home in a short paragraph

My paragraph:

I like my house very much because it suits my taste. It has three floors with four rooms and the third floor is used to grow vegetables. On the first floor, there are my brother's room and my mother's one. The space between two rooms is a common place that we use to our computer and organ. My room is on the third floor, and the laundry room is on the same. In front of my room, there is a small space that we use as a drying ground. But what I like most in my house is the garden on the third floor. My mother planted many kinds of vegetables, such as water morning glory, malabar spinach, loofah and bitter fruit, which are enough for the whole family's daily meals. Although my house is not big and modern, it is still very convenient for my family's life.
