STANHOPE boss Sir Stuart Lipton has attacked the house building industry for 'not changing much since Roman times'.
The developer believes costs can be cut by a quarter on house building jobs by changing the role of traditional builders.
Stanhope has a joint venture with Chelsfield to build 4,500 homes at Stratford City in east London.
Sir Stuart said: 'Imagine you are a Roman, you lived in a house made of brick and stone, it had a tiled roof and underground heating.
'Now scroll forward to the 21st century where you live in a house made of brick or stone with a tiled roof and underground heating.'
He said that house builders had been slow to adopt modern methods such as bulk purchasing of materials, threedimensional modelling and streamlined logistics handling.
