Cornwall Council staff will remain working in St Austell and Liskeard and will not have to commute to Bodmin, the local authority has decided.
There was concern among local government officers they would have to move to a new office complex planned for Bodmin, and could have affected 200 staff.
Costs in St Austell had been considered prohibitively high due to leased buildings, such as Sedgemoor, but it is hoped staff will now move to Penwinnick Road.
St Austell and Newquay MP Stephen Gilbert said he understood any move from the former Restomel Borough Council headquarters on Penwinnick Road would mean staff relocating elsewhere in St Austell.
Final decisions on the office strategy will be taken by the Cornwall Council’s cabinet next month, but only after the issue has been properly considered by the Finance and Resources councillors.
Mr Gilbert said: “The news that Cornwall Council will not be relocating the majority of jobs from St Austell elsewhere is simply fantastic.
“ I have been working with the council to ensure that those people employed in St Austell will not be forced to either leave their jobs or commute to Bodmin every day.
“Cornwall Council is a unitary authority but that doesn’t mean everything should be done in the same place. We need to keep our One-Stop-Shops open and make sure that county-wide services are decent for all and not just a few.’’
