Cool - so Livingston Deans would have been the 'holding' congregation that lead the project, which explains the 2014 income from the suggested per-publisher donations, though it is interesting that the income in 2012 and 2013 was also substantial.
Presumably the 2016 accounts, when submitted, will show the expenses for actually building the complex.
Dedridge and Whitburn's income and expenses can probably be explained by local fund-raising for new KH, with monies sent over to central fund held by the Deans Congregation.
It makes sense for Scotland to have a relatively centrally located multi-auditorium kingdom hall that can hold small assemblies - the documentation mentions a maximum expected attendance for assemblies here being 800 people - and as they're all one-day assemblies now they can be held on a Saturday and not interfere with the local congregation meetings on a Sunday.
