An English country house is a big fancy house that is usually located in the countryside instead of the city. It's where rich people used to go on holiday or sometimes live in permanently. These houses had lots of rooms with big windows that let in lots of light and some of them even had secret passageways! They were usually owned by lords or wealthy families who lived there with their servants.
There were lots of fun activities to do around these houses like going for walks in the pretty gardens, playing games like croquet, and even going on horse rides. Sometimes the owners of these houses would even have big parties with lots of fancy dresses and delicious food.
Overall, an English country house was a grand and fancy place for wealthy families to live in the countryside and have fun!
