A very enjoyable 1st episode which bodes well for the following programmes.
I always found Polizzi an engaging presenter, particulary with the 'tuff luv' she exuded on previous series.
Having spent my entire working life as a construction professional, she was surprisingly either badly advised or naive (for someone normally so savvy) or most likey a bit of both. Even from the most cursory of none instrusive surveys would have picked up those windows - flat roofs built in the '60s even if its not apparent visually are known money pits - from what was shown of the programme it was clear that roof was shot.
On a typical new build project it would be 'normal' to have a 10% contingency, on a building with listed status it should have been at least 20% > 25%. Particulary if something is uncovered during the works that the planners refer to the Department of the Environment for a final decision, whith the consquent delay of months. Given the the construction industry at the best of times is not reknown for on budget programme completions and the propensity of any alteration to the installed M&E installations always costing a fortune, the original budget/programme was optimistic to say the least.
A very interesting programme and it will be fascinating to see how it plays out in later episodes.
