Work should start on the £50m Rushden Lakes plans early next year after avoiding any further legal challenges since getting the go-ahead.
There had been a six-week window for parties to appeal Eric Pickles’ decision, but this has now passed.
A statement released by LXB this week said: “LXB Retail Properties Plc is pleased to announce that its planning permission for a 494,329 sq ft retail and leisure investment at Rushden Lakes is now beyond challenge.
“In June, the Secretary of State announced his decision to support the Planning Inspector’s recommendation to uphold the planning permission and the six-week period for further challenges under judicial review procedures has now expired with no such challenges being made.”
It added: “Pre-lets are already in place with M&S and Costa and further significant retail and restaurant interest has been received since the Secretary of State’s decision was announced.
“The group hopes to have secured all the pre-lets necessary in the coming months so that a start can be made on site early in 2015.
“It is anticipated that the first phase of Rushden Lakes will be open by May 2016.”
