Designed by Francis Thompson, it took the form of a 4 storey triangular building, with two of the floors being underground. Georgian in its design, It is one of, if not the earliest example of a purpose built commercial inn in the country.
The area was designed as a self-contained community, and the Inn traded continually as a public house, as well as offering accommodation, until April 1974. It was then shut and left to fall into disrepair, and along with the cottages was marked for demolition. Yet public outcry at the planned demolition forced the local council to reconsider and after protracted negotiations the Derby Historic Buildings Trust convinced the local council to sell the buildings to the Trust for renovation.
The shell renovations were completed in 1982, where upon the Historic Buildings Trust ran out of funding and the work on the interior could not be completed. The building again hung in the balance, until in 1987 local businessmen saw the potential for The Brunswick and purchased it from the Trust. Work on the building began straight away, and, on the 3rd October 1987, The Brunswick was reopened as a public house, and has remained so ever since.
Early in 1990 construction was started on an extension to give the Brunswick Inn back its original capacity to produce its own beer.
A traditional tower style brewery built over three levels, great care was taken to keep the brewery in keeping with the history of the Inn, with lines of windows and stonework following through into the extension.
The plant itself was installed in April 1991, and on the 11th June 1991 production of Brunswick Brewing Company beer began. The brewery has a brew length of 10 imperial barrels (16.36Hl), and a maximum production of approximately 1000 imperial barrels per year.
The brewery produces beer not only for The Brunswick Inn, but also for Everards brewery of Leicester (the owner of The Brunswick Inn), as well as the local free trade and beer festivals. Over the years the Brunswick Brewing Company has established itself up and down the country, and has collected many awards for its ale, from local festival awards to national recognition.
