The diagram records the changes that occurred in Tumbledown over a twenty year period.
In 1995 there was a school and a park north of the main road. There was farmland in the south-west and a farmhouse was attached to this land. Tumbledown had a hospital located near its center and a large woodland area near the hospital.
Tumbledown has a new look in 2010. The school and park have been replaced by a series of buildings, namely shops, a hotel and spa and a large science park and museum. The woods have been reduced to accommodate a hi-tech center. Tumbledown has grown in size and the hospital no longer exists. Finally the area used for farming now accommodates a science academy and laboratories.
Tumbledown and the surrounding areas have changed completely from 1995 to 2010. It has expanded and the green areas have been replaced by science and technology buildings, museums, a hotel and shops.
