Riverside Park is owned by private sector.

In 2001, Middlesbrough Council, with British Business Parks identified that the estate was ripe for renaissance.

Riverside Park had begun life as an Enterprise Zone. This meant that it attracted a wide range of different private sector owners. Not unsurprisingly, this meant there was no ‘joined up’ approach to estate management, investment and promotion. This affected the property market and at one time 40 per cent of the business units were vacant and brownfield sites undeveloped.
A survey (commissioned by Middlesbrough Council) highlighted several key areas for improvement, including: access; the physical environment; the condition of brownfield sites; security and the public’s and business community’s perceptions of the area.
