A 190 joist is not going to span that kitchen and dinner without a mid span support.
i need to tell building control?
so where the kitchen wall is supporting, the dining room has french doors so this isnt supporting or it it also
All external walls are structural/supporting walls.
Going by that plan, the ground floor internal walls going vertically are load bearing, and those going horizontally are not. But as always things need to be checked first.
£650 is a lot for an engineer and a simple beam such as would be required here. Check if your council actually need calculations to be provided, as many now will accept beams of certain size, up to certain spans.
The tricky thing here is getting the beam in the floor void, so you need an experienced builder.
I calculated my own online and have since been told by building control and the plan drawer that I need calcs from an SE. A thread in this section said my cat could do the calcs and it would be upto the councils own engineer to check them if they wanted them checking.
