The ALDI store at Wandella Road, Miranda, will close temporarily from Monday, August 3, to undergo a "comprehensive upgrade".
The store will be closed for more than three weeks to allow for the upgrade, which will include redesigned shelving, expanded wooden produce bays and extended energy-efficient chillers.
New energy-efficient LED lighting and improved point-of-sale displays and store signage will also be added.
It follows a trial and roll-out of the new-look stores across South Australia and Western Australia.
"We're excited to be undertaking these upgrades and welcome the community to visit our new store from Wednesday, August 26, and share their feedback about the store experience," an ALDI spokesperson said.
"While we're delighted to be introducing these innovations, we want our customers to know they won't lead to higher prices.
"Low prices are a big deal for ALDI. In fact, we refuse to be beaten on price. This is our fundamental point of difference and one we will never give away.
"ALDI Miranda Central shoppers will have access to the same award-winning grocery products and popular special buys, together with fresh fruit, vegetables and bread delivered daily.
The ALDI store at Westfield Miranda will remain open during the upgrade of the Miranda Central store.
An Aldi spokeswoman said the Aldi store at Engadine was also closed for refurbishment and was due to reopen today, August 1.
Aldi Menai was refurbished in 2017 while the Kirrawee store opened in 2018 with the new modern design in place.
There are no plans at this time to upgrade the Westfield Miranda store.
