Hello again all you engineers...
Cheers Ninja for meeting up with me that time in Edinburgh.
I now need a structural engineer for another job, possibly similar to what Ninja did for Pete I think.
We want to knock a cupboard out of our dining room, and move the kitchen to create a dining kitchen. Have added this drawing I did to give a rough idea of what's involved.

The cupboard is shown in the top corner, and the dotted red line is where I reckon the RSJs will need to go. We haven't actually got architects drawings yet, but we've sorted one out and hopefully will have the drawings within the month. We're looking to do the project in Jan/Feb, and want to ensure the plans/warrants are sorted in good time.
The kitchen will go along the top of the picture, and extend roughly halfway down the right hand wall.
The flat is top floor, with the cupboard walls extending below through the downstairs flats to the ground (ie original and supporting i would guess). The roof is flat rather than pitched.
Can anyone give any advice or tips on what'll need doing, either with taking walls out, or moving the kitchen?
TIA
