Scrubbie, I love it jolly well done I say as I am well known for crap spelling, on the house thing well my old pit has 10 ft ceilings in the rooms with massive windows, without being a total nerd there is housing with a similar style look to them in my local town I cannot see any non U.K. thing about them, the first house I ever bought was also very similar in style, it had stable style doors and sash windows that were as above in size and form, so I am going to say the house is a U.K. type home with the slide up or slide down section windows.
On to the engine thing that is powering the scraper, well in the Seatwarmer thing there is another very similar power unit stuck on the back of some other contraption with a very apt starting handle dangling from a rad cowl that looks all to like the thing on the scraper,I sort of thought I could see those little screw on plates saying Gardner near the top of each cylinder, but I also know that Dorman made a power pack looking like this and it was hand start or air start, I used to see a welding plant started by hand with rope pulled by 2 men hooked onto the start handle that looked crack on like the pack on the scraper etc, Gardner engines were not common to find fitted to mobile plant that I recall, I cannot realy think of ever spotting a Gardner engine getting a life of Hell on any construction equipment other than elec/generators but I am known for my lack of brains, the Dorman was an engine with an S.A.E. rate for running non stop with a load, even the fuel filters could be changed without stopping the engine, so this engine builder was targeting a use in construction type equipment with their Heavy Oil motors. tctractors
p.s. try A.C. on the tractors
