The trade-offs between having a prestigious building that makes a mark on the skyline but which is also a good place to work in are notorious. A spectacular landmark, such as London's 30 St Mary Axe, the Lord Foster-designed building known as the “Gherkin”, can literally put a business on the map and broadcast its owner's ambitions to the world. But monuments to corporate pride also create a host of challenges for their occupants.

“Curved funky structures use space inefficiently and can be expensive to fit out,” says Hugh Mulcahey, a director at Cyril Sweett, the property consultants. Tall, thin towers often wreak havoc with team working by splitting departments across several floors. And, while a soaring column may look good from the outside, hermetically sealed interiors can leave occupants feeling jaded.

Linda Felmingham, director of administration at Hunton & Williams, a US law firm that rents space in the “Gherkin”, says working in “a lovely building that everyone knows about” definitely has the wow factor. “If I get in a cab I don't give the address, I just say ‘The Gherkin',” she says.
