The closure, originally reported by Eater London, comes just over a year after Stem opened in Mayfair.
It comes after head chef Sam Ashton-Booth left the kitchen in April, while restaurant manager Emma Underwood departed earlier this year to join Robin Gill's Darby's at Embassy Gardens, Nine Elms.
Jarvis says in a statement: “I have closed Stem restaurant for the time being, while we re-evaluate our plans for the site. It has been increasingly difficult over the last few months trying to trade successfully with intrusive ongoing building and street works right in front of the restaurant. No decisions on the future of Stem have been made as yet.”
Jarvis previously ran Neo Bistro in Mayfair, which closed this year after he stepped away from the project.
The chef remains focused on his inaugural restaurant Anglo in Farringdon, which was named Best Newcomer 2016 in the Observer Food Monthly Awards.
Jarvis started his career at Raymond Blanc’s Le Manoir aux Quat’Saisons and has also cooked at Texture in London and The Bingham Hotel in Surrey.
