There are differences throughout the world. In Poland, typical foundation looks different - often there are horizontal "foundation walls" , and not only foundation support under the columns (or alternatively - only a 15-30cm thick concrete slab). Also, there's thermal insulation everywhere - all over the foundation, under the floor, on the walls, under the roof, around windows and door, etc.
at 7:29 you made a mistake columns should never be layed after brick work, in case if column is casted after brick work than the brick work becomes the part of column and starts to bear load and withtime develops cracks, so always column should be casted first and after removing shuttering the brick work should be completed, if you have some columns yet to be casted and the brick work has already begun than avoid brick work adjacent to column to avoid any load bearing connection b/w wall and column, until you believe your walls are load bearing walls and can bear load quite easily. Anyways really a informative and detailed video, good to created curiosity in new aspirants .. looking to make carrier in construction.
Where is the sill beam Lintel beam You should concrete columns first then you should do brickwork You should do plumbing pipes fitting before plinth beam... But you did it later
There are still constructive errors in this but gotta say it goes hard for a video that shows the basics of construction work, won't blame the creators for not doing the last part of additional secondary stat bodies and the wood work as well since this concerns only the concrete placement in the project
