As far as we know, Nicholas Hawksmoor never designed a bouncy castle. If the Christchurch Spitalfields architect had turned his hand to inflatables, he might have come up with something like this riot of arches, columns and upturned pediments.
The playful installation is the work of Camille Walala. Like the building she painted on nearby Old Street and her maze in Greenwich the inflatable structure and its surroundings are a medley of bold colours and stripes.
The sculpture can be found in Exchange Square, just behind Liverpool Street Station. It was commissioned by British Land, part-owners of Broadgate, as part of the 2017 London Design Festival.
Visitors can walk around or through the sculpture, and even sit and eat their lunch on the periphery. Sadly, you cannot bounce on it.
The work is so eye-catching that even the heads-down phone zombies of the Square Mile are unlikely to pass by without giving it a glance. Our toddler will love it.
Villa Walala, as it's called, will remain in Exchange Square until Sunday 24 September.
