The company wants to add single storey extensions to shops in Milford, Ballybofey and Bundoran – all three will be 133 square metres in size and include parking extensions.
It’s thought there will be objections to the extensions from existing businesses in all three towns.
Anyone wishing to object needs to do so within five weeks.
The company has successfully developed across Ireland with 109 stores now – and has managed to grab a large share of the Donegal retail market through aggressive low prices and quirky offers.
Ballybofey, Milford and Bundoran have been successful and Lidl wants to expand to cope with demand.
