Ok 11k sq ft for £2m - where on earth do you live?
I lived in a 7k sq ft home a few years back and we downsized - it was too much for where we were and what we needed. We had 6 bedrooms, all ensuite with walk in wardrobes, 5 reception rooms, staff accommodation gym, offices etc etc
What is your favourite random/interesting room? You know the one no one else has and is slightly redundant but brings you joy.
