This Victorian pumping house can only be described as spectacular. A temple to Victorian ornamental cast-iron frivolity. Polished brass, ornate cast iron columns, spiral staircases and endless creative detail. Situated a little way outside London but the effort to visit this building will be well rewarded, you will spend for evermore boasting to your architectural colleagues of what you have seen.
