Lewis (pictured), Conservative MP for Great Yarmouth, will become housing and planning minister at the Department for Communities and Local Government.
He had previously been a parliamentary under-secretary at the same department since September 2012.
Previous housing minister Kris Hopkins remains in the department but his future role is unknown. He had been housing minister since October 2013.
Lewis will become the fourth person to occupy the position of housing minister since the current government came to power. He follows Grant Shapps, Mark Prisk and Hopkins in taking on the role.
Lewis also takes over the planning brief from Nick Boles who has been promoted to the role of Minister of State, splitting his time between Department for Business, Innovation and Skills and the Department for Education.
