Six new homes have been demolished - after builders used the wrong type of cement.
 

The new builds, which were part of a 38 house development in Hurstpierpoint, were knocked down as a “precaution” by construction firm Croudace.
 

Neighbours close to the Chalkers Lane development said diggers moved in one day and “crushed” the part-built houses to the ground.
 

Garry Rapson,  building director for the firm, said the blunder was down to “human error”.
 

He said: “Chances are the buildings would have been completed and there wouldn't have been a problem.

"However, we wanted to make absolutely sure there would be no problem and no inconvenience to whoever was to live in the properties.”
 

The homes are due to be completed in 2015.
