Plans for IKEA to move a massive distribution centre into Stanton are so delayed, planning permission could run out.
As the furniture giant and Suffolk County Council work out a deal on road improvements, time has dragged on.
Now the owner of the site, Rossfleet Ltd, is applying for planning permission for the site to be extended beyond May next year so a deal can be struck, or in case IKEA pulls out.
In a letter supporting the application to extend planning permission, Rossfleet Ltd's architects said: "IKEA has had a planning application approved by the committee for a warehouse distribution complex, but there is a Section 106 involved as yet to be completed.
"Our clients are anxious to renew their existing consent in case it should lapse before the formalities are concluded."
Section 106 agreements are extra conditions added to planning permission which IKEA will have to meet before it can build on the site, next to Bury Road and Sumner Road.
Rossfleet said it would not comment on the matter.
A spokesman for IKEA said: "IKEA is still in discussion with the local authorities on the application for a distribution centre in Stanton.
"The two parties are in the process of negotiating the terms and conditions and IKEA cannot make any further comment until this phase will be finalised."
