Hi, thanks for your recent and ongoing mapping in the Lakes. 

Based on the name you've added, would the holiday cottage be better tagged as building=barn with building:use=residential/chalet? This would better reflect the building's original purpose and architecture, if indeed it is a converted barn and not just a building with an idyllic-sounding name for marketing purposes! This also applies to the other holiday cottage/barn you added. https://wiki.openstreetmap.org/wiki/Key:building:use :)
