Answer 1

Let me get this right - you want to find out if there are any building regulations regarding replacing timber floors with concrete?

To answer your question directly, I'd say that if you're looking to replace an existing floor with concrete, you need a structural engineer to certify the job and include that in the building warrant application that you'll need to submit. They'll be interested in the structure (ie: what's going to support the new concrete floor, is it suitable for the increased loading, what are the reinforcement details, etc.?). If the concrete floor is to be on the ground level, there are also issues with moisture/dampness control.

But the thing that's more likely going to stop you is the fact that the building is 500 years old. Chances are it's listed, and you are going to need to apply for a listed building consent to do anything to it. Call your local council to find out what category it's in.

If it is listed, then you are most likely going to need to replace like for like. That just means that you can't be replacing timber floors with concrete willy nilly.

Answer 2

Most old homes like this are not setting on the ground- the have a partial basement, or crawl space- or is this a basement floor-
Thickness of a 2x4 will do fine- when you pour concrete. except as footings.

Answer 3

then you'd better check that it isn't a listed building as if it is they won't let ya concrete it but they will allow you to replace the floorboards
