The kitchen. The Crest branded copper-plated stove is a brand of miniatures, rather than an actual stove brand. The copper is for show. Early stoves were made of cast iron. The stove in this kitchen is much later than 1810. In 1810, the kitchen would have had a cast iron stove such as a Rumford stove set into a brick hearth.
The copper pans are appropriate to the era. I found this website that displays an extensive collection of copper from the 18th and early 19th centuries in the kitchen of a French chateau:
