Cavan firm, Woodford Timber Products Ltd has applied for planning permission in recent days.
The well-known local business is looking to extend its operations with the construction of an oil-based timber preservative treatment plant building.
Their application also includes plans to add an adjoining lean-to structure containing a biomass boiler.
The new development at their premises at Kiltynaskellan, Doogarry, Cavan will be used for the treatment of timber products to be used in conjunction with the existing onsite timber products business.
Cavan County Council are expected to make a decision on the application in the new year.
