In Chapter 2 of The World Without Us, Weisman explains what would happen if we were to leave our homes and never return. This video shows exactly that.

Within 10 years: Moss begins growing over the roof.
15 years: Ants, cockroaches, and other bugs take over the house. Termites chew at the foundation.
20 years: Roof starts to come apart- shingles fall off.
25 years: Nails can no longer hold together the floorboards.
30 years: Paint deteriorates and bare walls are exposed.
35 years: Grass, mushrooms, fungi, and other plants begin to take over lawn and crack the concrete.
100 years: Animals invade the house and surrounding area.
125 years: Plant growth causes the house to collapse.
175 years: Debris from the collapse is broken down by weather and plants. All that remains is the chimney and metal parts.
240 years: Rain wears down the metal, causing it to rust and crumble. Chimney still remains.
250 years: Chimney begins to crumble.
300 years: Plants break down the crumbled metal remains and roof shingles.
340 years: Trees and larger flora surrounding the house continue to grow, and chimney continues to crumble.
390 years: Metal fence is broken down by weather.
500 years: No part of the house is left standing. Some parts float down a nearby river.
