The 3,500 sq ft space, which is now operational, features a new 25kg roaster, climate-controlled storage room, and laser analysis unit, while the brand overall has seen a complete design overhaul, with a new "W" logo to appear on all of its shops, as well as its coffee packaging.
The roastery is set to open to the public as a shop, as well as offering visitors the chance to see the roastery in action, in the New Year.
The four-shop group, which is owned by founder James Dickson, has also re-designed the height and shape of its online-order coffee bags, with each re-sealable pouch now capable of fitting through any letterbox.
Workshop Coffee's head of production, Richard Shannon, commented: "With these resources we hope to better analyse, learn and develop our understanding and control of the different elements that help create the best coffee possible. Above anything else, Workshop Roastery will allow us to continue improving quality control, whilst also allowing us to meet the incredible demand we've had."
First launched in the UK in London's Clerkenwell by Dickson in 2011, Workshop Coffee used to be known as St. Ali (after the patron saint of coffee, Ali Ibn Umar al-Shadhili). It rebranded in 2012, with its parent company name changing from Long Black to Workshop Trading.
It now has four sites across London, comprising Clerkenwell, Marylebone, Holborn and Fitzrovia, plus the roastery in the east of the city.
