Anish Kapoor

Designed by Anish - built by Kirk, Matt, Andy, John and Wayne

Standing nearly twice as tall as the Olympic Stadium, the crazed and twisted steelwork of the ArcelorMittal Orbit tower is an undeniably impressive piece of engineering. Consider that it was bolted together by just three men, and its loops and spirals seem more imponderable than ever.

Paddington's Merchant Square building is a bit of a mind-bender

Britain is awash with large commercial buildings whose façades have been tarted up with supposedly creative gubbins because planners encourage the so-called Per Cent For Art approach. We're not talking Anish Kapoor. Nine times out of ten, that 1 per cent of building cost pays for witless "artistic" glass fins projecting from façades.

Anish Kapoor has fallen victim to the artistic scourge that is health and safety while working on his large-scale work for London's Olympic stadium. Nervous officials have forced the artist to add a high mesh to the pedestrian walkway which winds its way up the 120m ArcelorMittal Orbit tower, both to prevent visitors from falling off and from throwing objects at the crowd below. "It's way over the top, irritatingly over the top, but that's life," says Kapoor. "You have to, kicking and screaming, find a way to negotiate those things. They are really hard work – you either cave in or you say, 'I want to do it that way, we'll have to find a way to make it work.' I'm a horrible fighter." Further afield, the sculptor is preparing to open his first exhibitions in his native India – one at the National Museum in Delhi and another in a spectacular Bollywood film studio in Mumbai – and is working on a plan to fill Paris' Grand Palais (the French equivalent of Tate Modern's Turbine Hall commission) in 2011. Details are still top secret but the work will involve inflatables. "It's playing an architectural game, reversing what's inside and outside the building," he adds.

On the agenda: We're off to the shops at St Martins Lane Hotel, then

Just when you thought Dover Street Market, the fashion emporium created by Rei Kawakubo of Comme des Garçons, couldn't get any cooler, they go and build a pop-up store at London's St Martins Lane Hotel, home to the A-list hang-out Bungalow 8. Well, 'tis the season: there are pre-Christmas pop-ups everywhere, but not many offer such a range of fashion-forward festive treats. The six storeys of the shop have been edited into a slick capsule, including CDG diffusion lines Play and Shirt, as well as the store's own new label. Open now, until 8 January. Harriet Walker

Anish Kapoor, Royal Academy, London

The silliest work in the Anish Kapoor exhibition is a kind of shooting range. A cannon is aimed through one of the Royal Academy's ornate doorways. (The public are safely held back.) Every 20 minutes, an operator loads it with a bucketful of deep red gunk. It fires. The gunk hits the wall through the doorway, dribbles down, piling up at the bottom, with much spatter. This will accumulate over the next three months.

He is both loved by the public and respected by his peers, and soon the Royal Academy will host a huge retrospective by one of the most distinctive artists in its prestigious inner circle. Charles Darwent meets Anish Kapoor
