Help finding British "horror" movie..

Thinking I saw this on netflix, it was british for sure, and was from about 2012-2015 or there about.
The plot was either an english man or woman, getting married, and the spouse was american, and they convinced them to live in the old family home or something similar.

The wife kept going to the garden that was overgrown, and was all into cleaning it up and found some old ancient statue of some creature.
It then was basically a psychological horror type story, about the husband and wife.

The house was quite large and expensive and old looking if that helps.
They were fairly rich.

 

Wife was a redhead, and quite cute.
