About this property

Castelnau doesn’t really do subtle. It is the kind of address that announces itself before you even arrive, grand, historic and confidently elegant. This is one of those rare Barnes homes that feels less like a house and more like a private estate: seven bedrooms, exceptional proportions and the sort of footprint that makes most London homes feel rather modest by comparison.
