Finance Minister Peter Robinson is set to announce the executive's final budget to the assembly.
It is understood more than Â£200m will be allocated to build more than 5,000 affordable homes.
The executive parties clashed over the draft budget published last year, but the final document was agreed by all ministers on Monday.
The Ulster Unionists also say they are happy with their settlement on health, which includes Â£30m in extra revenue.
An extra Â£40m in capital is due to be spent on the roads and Â£14m on the fire service.
Last year, Mr Robinson clashed with Housing Minister Margaret Ritchie over a variety of issues, whilst Health Minister Michael McGimpsey led the charge against October's draft budget claiming it was selling the health service short.
