Bewley's café on Dublin's Grafton Street shut its doors last week, after making losses of €1.2m a year - which the company said were unsustainable.
The café said the changes are "to secure its long term future on Grafton Street, where the café has a massive rent burden and is currently significantly loss making".
This will include a refurbishment and restoration costing more than €1m.
The premises has not been renovated since 2005 and Bewley's said is in need of work now to ensure its conservation and a suitable environment for customers.
It is planned to re-open the café with a simplified focus on the ground floor and basement. It is thought this reduction in scale will help reduce costs.
