My dream house will be a villa. It will be by the sea. It will be big and comfortable. In front of the house will have a swimming pool and many flowers. Behind the house will have a garden. We will see blue sea. In my dream house will have some robots help me do house work, wireless TV help us watch TV programmes from space, a fridge modern help cook meals
