The RAP has asked their readers to write about their homes.Well,i live in a detached house in Bristol.
In our house there are three rooms downstairs and three rooms upstairs.The three rooms upstairs are all bedroom.Out living room is downstairs.There is a sofa and an armchair in the living room.There is also a table with three chairs,a TV set,a DVD player and a video recorder there.
Most houses have a bathroom upstairs,but ours is downstairs.In the bathroom there is a toilet and a shower.Some houses have a bathtub,not a shower.
If you come into my house through the back door,you will find yourself in the kitchen.In out kitchen there is a fridge.There is a freezer under the fridge.We have cupboards for food and for plates.There is an electric cooker.We don't have a microwave and we cannot cook our food quickly.There is a washing machine which Mum uses for doing laundry.We don't have a dishwasher and i help my mum with washing up in the sink.
To the rear of the house there is a back yard where our playground is.I can ride my bicycle there, too.In front of the house thereis a lawn with beds of roses.It's very pretty.There are two benches to sit on.I love the place and enjoy reading a book there!
