HOME building in Tower Hamlets is continuing to grow – with the borough recording the second highest number of construction sites across London.

Tower Hamlets was only behind Newham in the number of new developments within its borders, the latest London Residential Crane Survey showed.

But housing experts have warned that there are not enough family sized homes in the pipeline.

Some 4,050 units of housing – most of them flats – were being built in the last six months of 2010 in the borough.

That was an increase of 16 per cent from the previous six months leading up to summer.

Big projects in the East End include apartment blocks in Lanterns Court and Baltimore Wharf in Canary Wharf and at Caspian Wharf in Bow.

Newham had 4,100 homes under construction – most in the Athletes’ Village.

Between them, Olympic boroughs Tower Hamlets, Newham and Greenwich have 40 per cent of the homes currently being built across London.

The majority are private investments rather than public housing.

Across London, 95 per cent of all units being built are flats.

Anthony Duggan, head of research at Driver Jonas Deloitte, who published the report, said: “Family housing is a real issue for London and this research shows the seriousness of the problem.”
