So my questions a

1) Bearing in mind this is a small house which best suits a professional
couple or, at a push, a young family, will adding a third bedroom increase
the value of the house?


Probably not

2) Will people be put off by having to go through one bedroom to get to
another?


Yes - in a big way

3) Will I have to seek planning permission to do all this?


Dont know, call the planners and ask.

With the limited info provided - you would be better advised to get the
ensuite working with the money you are planning o spend on the
conversion.
