The Hartley Botanics 31-metre glasshouse in the newly developed kitchen garden at the luxury hotel and spa will be open for the first time since the 1940s, when the original 1840s glasshouse fell into disrepair.
The glasshouse forms part of the new Walled Garden at Wynyard Hall which opened in 2015, realising Sir John Hall’s long-term personal ambition to create "one of the UK's most exquisite rose gardens".
Metnor Construction are responsible for the build with 20 men on site each day, drawing on the expertise of locally sourced subcontractors and suppliers.
This year, Sir John’s daughter, Allison Antonopoulos, is embarking on her own vision to extend the Wynyard estate even further through the creation of a Victorian-inspired Glasshouse, Potting Shed and Edible Garden.
Antonopoulos, who is hotel managing director, said: "The Glasshouse and Edible Garden will be a place to inspire people who share my passion for horticulture, cookery and floristry. We have created a whole host of events that will be held in the Glass House, which is a fabulous, vast space – perfect for group activities."
Paul Mackings, chief executive of Wynyard Hall, said: "We have gone back to our Victorian roots here at the Wynyard Estate. All of the food that we grow in the Edible Garden will be at the heart of our menus in the Wellington Restaurant and Café. Visitors will be able to purchase the fresh produce at the Farm Shop and Potting Shed. It really is as fresh as you can get."
This third phase of the garden’s project is part of a bigger, £6m investment: "The legacy of the Wynyard Estate is really important to us as a family. Some time ago I recognised the need to create a sustainable development that will ensure Wynyard Hall is maintained for future generations.
"It’s an ongoing restoration project. At present we are restoring the beautiful follies, pathways and monuments that have never been seen by the general public. There is so much history dotted around the estate and it’s a shame for it to be hidden away.
"Next year we plan to open more of the historic parkland up to the general public, with picnic areas and lots to see and do for families."
The Glass House, Potting Shed and Edible Garden open to the public on 11 September. CBeebies favourite, Mr Bloom, will make a guest appearance along with themed entertainers, face painting, arts and crafts and more.
