Former chief executive Nicholas Marshall moved the 148-garden centre group from Slough to the Duke of Northumberland's estate in west London soon after taking over in 2009.
Head office staff moved into stable house where the Duke helped fund a refurbishment, which saw the staff move onto the garden centre site at Syon, opened in 1968.
A Wyevale representative said: "We’re a growing business and our team has expanded in recent years. It’s important therefore that we have an office space that’s fit for purpose, accessible for our people and appropriately supports our future growth. We are reviewing our options at present and will continue to keep colleagues updated on progress."
Meanwhile, former Wyevale regional operations director Melanie Evans has become Shoppers Anonymous regional director South Wales.
Former Wyevale retail trading director Dan Zinner is now transformation director (interim) at the Restaurant Group.
A new operations director is starting at Wyevale to replace Colin Hughes.
