Order of work

Hi all my project is a two story extention i have the shell up the roof on,and fitting of windows doors next, then rendering to the outside to match the rest of the building, what is the next thing to be on with not sure of the order of work to be done. ie floors upstairs stud work etc is there a web page or any info that will be useful to me.
Thanks Laurie.

You'll need to put the floors in so that you can walk on them!

Then any stud walls so that you can do the first fix electrics, plumbing and heating. Then door linings and any first fix carpentry.

Then plastering, then second fix carpentry, electrics, heating, plumbing. Then decorate

Hi thats how i thought it went ,its just nice to have it confirmed,two heads are always better than one.
thanks for your quick reply.
