The figure is up from the 92,500 which Bristol, North Somerset, South Gloucestershire and Bath & North East Somerset councils agreed two years ago.
The Government has today released details of a report by an independent panel which recommends the area should take far more new houses than previously suggested.
Bristol itself needs 30,000 new homes, an increase of 2,000 properties. These will be built mainly by infilling between existing homes or redeveloping brown field sites and derelict inner city land
But the biggest increase comes for South Gloucestershire, up to 30,800 from 21,500.
