hi roger we would be able to all depending where you are based. let me no,,,,,,

Like Jonathan already stated, this isn't going to be the spacious luxurious master suite you have in mind. If the majority of the stairs is on the floor below, you could have this layout, for example. The pale grey is the area where you can't stand up straight. Again, really really make sure the joistst can handle all this weight! Otherwise just turn this into a kid's loft and make a nice spacious family bath on the bedroom floor. With a separate toilet of course. ;)

Ellie, the structural engineer does not appear to have given design heights to the underside of the new beams. This may well be intentional as he may not be sure what is above your existing ceiling unless he cut out a small test hole to carry out an inspection. He should however be able to give you an approximate height to the underside of the beams which would include the plasterboard cladding, which as Verity * Beverley rightly pointed out will almost certainly be required. It will then be up to you to ensure that the builder does not go below this height as it may affect the heights of your kitchen wall units. Not a big problem for standard wall units but a nightmare for a floor to ceiling unit. Make sure that your builder is aware that this is a "critical" dimension. In conclusion speak to your structural engineer and he will give you an approximate floor height dimension that you can work to allowing you to design your kitchen. Best of luck with you project!

As for me, the most important thing is the civil engineer. He needs to make all calculations for technical changes, taking into account the likely load and the use of specific materials. He may also suggest making changes that can make the project cheaper or more expensive. Honestly, I always thought that it would be easier to look for such a specialist through the architect's office, even if you already have a finished design project. I know that these companies only hire employees with a good resume like this example - https://resumewritinglab.com/construction-resume-writing-service.html There are no random people without experience. And it also gives you additional guarantees on the quality of the work performed.
