I'm quite familiar with big houses. Growing up during my years in Hong Kong I lived in my grandparents' house which was a 7000sf villa, had 8 bedrooms. You could park 5 cars in there and had some areas. That house isn't big by UK standards but by Hong Kong standards it was huge as the average home is less than than 600sf there and vast majority of people live in council type flats. There were 3 servants who did everything from prepare food, keep the house clean and made sure me and my cousins were behaving, 1 of them was an English lady who was handpicked specifically to be a governess, while the other 2 were from Hong Kong and all 3 lived in the house. Sadly that house no longer exist as they sold it upon passing of the grandparents and after that the house was demolished to make way for a high rise building.
My parents had a penthouse that they called home when they were in Hong Kong, I went back there during the weekends only in my younger days. It was big by Hong Kong standards as it was 2500sf and had 4 bedrooms. This place had a maid from Philippines, she worked for them for 18 years. I think my parents would have given me a good thrashing if I treated her like a maid.
After I graduated, started working and lived on my own I've lived in several homes in UK, from small tiny London flats to big estates in the country. The biggest of them was this 200 acre estate which had a 9 bedroom house. I didn't like it all that much as it was a pain to get to as I worked in the City and that house was nearly 60 miles away. I found the commute to be the hardest part as after work I just want to get home and not be stuck on the M25. When I had that house, I did have a cleaner from Czech who brought with her an army of hands to keep that house clean. The gardens was maintained professionally until I decided to have most of it converted to woodlands but I then moved to a smaller semi-d closer to the City as I got tired of staying so far away, house was a fairly large 5 bedroom. The same Czech woman maintained the house and I had one OAP manage the gardens in exchange for his tab at the local pub.
Now I live in a very normal 4 bedroom townhouse that is 20 minutes drive to work, it is a very normal middle-class type neighbourhood. It is above average in size by Swiss standards but it isn't huge just around 1600sf. Not into the big house thing any longer as in Switzerland owning such homes attract higher wealth/asset taxes and they are also incredibly expensive. Staff? When I first moved here I had a cleaner from Poland who came twice a week. Then my OH moved in, she doesn't like other people in the house especially the bedroom as she considers it to be her private domain, we don't have any cleaners now but she does 98% of all household chores
I did try to help her but each time I do it she starts nagging me that it is still dirty and she had to do it again, plus she wanted everything to be spotless everytime I told her either she did it or I'm getting a maid.... she now does it. Garden, I do live in the end unit with a bigger side garden, I made a deal with one of my neighbours, an elderly couple that if they maintain my garden then I will pay for the cleaning of their solar panels, windows and their share of the maintenance charges, was a win-win situation
