Described as a "Playground for Experimentation, Invention and Curiosity", Gin Palace and distillery has been expanded to meet the growing global demand for Hendrick's gin.
The new site will now be home to the distillery's stills and master distiller, Lesley Gracie, who will have the creative freedom to "experiment and conceive new Hendrick's variants".
The Hendrick's Gin Palace doubles the brand's capacity to meet demand and features a "mysterious and enchanting" walled garden which leads to a Victorian inspired palm house.
This is flanked by two botanical hot houses used to cultivate a "plethora of unusual botanicals and flora from around the world".
Inside, Lesley's laboratory features a flavour library, a lecture theatre and a stylish bar.
Two new still houses have been created as part of the extension, with The Hendrick's set of stills now standing at six, with four Bennett stills - including the original antique copper pot still hailing from 1860 and three precise replicas - and two Carter Heads - including one original constructed in 1948 and one exact reproduction.
The team say the new stills have been active for almost a year, and the fact that William Grant & Sons, the family owned spirits company, have invested £13m in the expansion, is "a reflection of the confidence and excitement it has in the future of Hendrick's".
Lesley Gracie, master distiller for Hendrick's said: "I've been distilling Hendrick's for almost twenty years and during that time, my team and I have had the opportunity to explore and experiment on a small scale.
"However, I'm thrilled and excited to take full advantage of our wonderful new distillery and begin working on a line of experimental liquids, some of which will hopefully blossom into future releases and potential new expressions of Hendrick's."
Pamela Selby, the global brand director for Hendrick's added: "The Hendrick's Gin Palace in its design and experience, is intended to inspire curiosity, open minds and serve as a platform for invention.
"It pulls back the curtain on the wondrous production method and showcases the many layers of Hendrick's that it has become celebrated for, some humorous, others curiously intellectual, detailed and deeply meaningful. It represents the confidence we have in the brand that helped to kick-start the ginaissance and leading role it has played ever since."
