Don't trust any answer you get on here, speak to a quantity surveyor. The answer lies in mathematical formulae which they will work out for you.

If any rsj work is to be carried out you must really get a structual engineer to perform the calculations, guessing or being advised could get you in trouble. If building regulations are required for the building work you are carrying out the local council will need these calculations before work can commence, remember they may even require in-situ cast padstones etc. Get the number of good structual engineer they will steer you in the right direction, hope that helps

Depends what load it is carrying above.If it in a 1930's or Victorian two story house domestic house and it is only carrying the floor joists and a partition wall above, it probably is about right.
If its carrying a load bearing wall and roof structure it would be worth asking a structural engineer or architect and possibly save yourself thousands for the cost of a few pounds

the council building inspector will TELL you what he wants if you are doing it without notification to the council they can make you put it back in the condition before you started the job
as the previous answer if it is one up one down then an 8x4 would be ok

what load is it bearing, and are their any support joists, or is it a straight 12 foot span?
a 8x4 wil do if its a house, single floor... but a 12 feet unsupported span... 8x10 or even 8x12, ask your building inspector.. dont guess..the inspector has the authority to MAKE you take it al down and do it properly... lives depend on it...mainly yours

There were so many woodworking plans with this collection and you will not believe this but there are over thousands plans in the one package deal. Go here https://tr.im/QzmLp
This is really something to find that many all together. For someone like me who is just really starting to get involved with woodworking this was like letting me loose in a candy store and telling me I could have anything I wanted. That was my dream when I was a kid.
