A senator has hit out at plans to provide no social housing in the State's tallest apartment block, Capital Dock.

It has emerged that Kennedy Wilson, the developer behind the 22-floor, 190-apartment Capital Dock project, are planning to provide social housing units three kilometres away in Rialto.

Dublin City Council has said these plans are not yet finalised.

Speaking on RTÉ's Drivetime, Labour Senator Kevin Humphreys said the plan is not in keeping with the spirit of legislation that requires developers to provide social housing within the community.

Under the planning laws, developers must provide 10% of any development of ten homes or more to local authorities at a discounted price for use as social housing.

Mr Humphreys said it was expected that 40 such units would be provided in the docklands due to the development of Capital Dock and another project.

He claimed that sites were available within the local area that could provide the offsite accommodation and the developer was not pressured into taking these.

He said that "in the previous boom we had an integrated community in the docklands."

The senator added that it is unacceptable that Dublin City Council has said it is unrealistic to expect affordable housing within the city centre.

"We need to make sure that families that have been living in the docklands for generations have an opportunity to get housing.

"We have to make sure people who have been living in the city for generations get the opportunity to stay living in the city," he said, and integrated planning was the way to ensure this happens.
