Describe your house:

My house which my dearly beloved family is living in has been changed during recent years.
In the past, when it wasn’t rebuilt, it was rather simple and small. It had been roofed with palm leaves which had been planted a lot in my homeland. Besides, it was covered with the brick walls. There were only a main- doors, 2 side-doors and 2 rooms. Due to the narrow space, my family often went to bed on floor with the leaf bed. Although it was small, it was covered by the fresh, large and beautiful garden. There were many fruit trees. And there is a well in the middle of garden. My parents usually put some kumquat pots and peach pots when Tet festival came up.
At present, my house is quite modern and comfortable. It was rebuilt 4 years ago. A new house was totally established. It was covered with water paint and green slates. Its inside space is quite large. A bottom floor includes a living room and a kitchen full of electrical appliances. Meanwhile, the second floor and third floor include 4 rooms, each of member family possesses the local authority decided to open a new highway cross my garden makes our garden smaller and more narrow. Therefore, there are some trees and some decorative plants in my garden. And the well disappeared .
In the future, my family will build the wall surrounding the house. Many appliances will appear and be applied in my house. Sometimes, my family will additionally build some essential rooms such as: a gym room, a book room or a roof-garden.
