Extensive historic details about the building can be seen at:
CROSS HOUSE, Tewkesbury - 1201228 | Historic England
Historic England also state: “Thomas Collins, the one-time owner and working stone-mason, has been referred to as "... the first important conservator..." in Tewkesbury (VCH), and was engaged in many important works in the town from 1860 onwards - before the major turmoil raised by the 1870's proposals to restore the Abbey. There is no doubt that he saved many important structures from loss through decay or demolition. His work at Cross House was substantial, and it is difficult to see what the original layout may have been; as much as possible of the early work was clearly retained, but it is not clear whether, for instance, the detail of the main lobby is as originally located or not. Collins is commemorated in a prominent memorial in the south transept of the Abbey”.
I think it is safe to say that the current project has a lot to live up to!
