Describe the house of your dreams!
The kicthen, the bedroom, and the living room - good :)
This exercise is asking what you would like your house to be like, so you could say the following:
My dream house would be a beautiful mansion, which has a beautiful design and a great scenery.
My dream house would be a simple house, that is cosy and comfortable to live in.
My dream house would be large and spacious, with a beautiful garden.
I pray this helps ^_^
