I always loved going to Ogmore and Southerndown. I thought the cliffs there looked like a building anyway. A building capable of withstanding the roughest weather for hundreds of years. The older they get, the better they look. I wondered if it would be possible to make a building which had the same qualities as these magnificent cliffs. To do that I needed a lot of stone. Normal stone for buildings has to be specially cut into blocks; it takes a long time to make and costs a fortune. But in north Wales the historic slate industry has left behind whole mountains of waste stone that no-one wants. This was stone cut from the mountainside for nearly two hundred years but which wasn't good enough to make roof slates. Over 90% was thrown away. But it was ideal for making walls like the one I had in mind... "—architect Jonathan Adams"
