What is the sign on the gate?possibly the name of the cottage.
Believe me I have tried every technique to try to read that sign - no joy.
I do not know about thatching styles but an "architecturally inclined friend" says the building construction looks odd for Wirral, and he suspects Wales. A hunch no more. That is possible because there are family links to North Wales.
On a different tack one point that intrigues me is that this photo is clearly a "family photo" and yet it is printed as a postcard. Was that a normal sort of procedure in the past?
These days with digital imaging etc it would be easy enough to do but some 80 (?) or more years ago prints of this type would be specials and cost more - and our family did not have spare cash for luxuries.
