My wife and I are renovating an 1870's house. Under the lounge carpet is
what I presume to be the original Flagstones "great" you might think!

Problem is I was hoping for a screeded floor, as we intend on laying
parquet flooring in a double herringbone pattern and as I am sure you
are all aware, a flat surface is required. Well the flagstones by
nature are not flat!

Here are my options as I see it:

A. Cover the flagstones in a thin screed, a shame to waste them and
thin is not good, cracks etc.

B. Take out the flagstones and try to sell them on ebay, lay a new 4"
concrete floor for the parquet flooring.

C. Forget it and lay some new carpet.

What are these "flagstones" like?

Replacing the "flagstones" with concrete will be best, if you really
want a parquet floor, as thin screen is iffy, and the stones may rock
enough to be a problem anyway. Option "C" is obviously the easiest.
Making a feature of the floor, but covering most of it with a large
rug or rugs may be nicest. Up to you.
