The development has been led by The Newt’s creative director Karen Roos, who is also the owner of Babylonstoren hotel and winery in South Africa.
The 23-room hotel is spread across the Grade II-listed Hadspen House and its neighbouring Stable Yard, and also features acres of formal gardens.
The hotel’s facilities include a spa, indoor and outdoor pools, plus gym and restaurant offering a “garden-led” menu.
Hadspen House is home to 13 of The Newt’s rooms, while the other 10 are in the Stable Yard including four with kitchen facilities.
