The new house, the one my parents had built at the bottom of the garden, between the azalea bushes and the green circle in the grass we called the fairy ring, that had been sold thirty years ago. I slowed the car as I saw the new house. It would always be the new house in my head. I pulled up into the driveway, observing the way they had built out on the mid-seventies architecture. I had forgotten that the bricks of the house were chocolate brown. The new people had made my mother's tiny balcony into a two-storey sunroom. I stared at the house, remembering less than I had expected about my teenage years: no good times, no bad times. I'd lived in that place, for a while, as a teenager. It didn't seem to be any part of who I was now. I backed the car out of their driveway.
How does the writer use language here to describe the new house ?
