Creative Quarter | Not so bored-rooms

Among the fun-filled offices is S3's Cardiff HQ, which ensures workers are entertained with an 18-hole indoor mini-golf course, adult ball pool and table football.

While visitors to call-centre Moneypenny, in Wrexham, Wales, can enjoy meetings in the company's tree house conference room.

Experts say an office that stands out from the crowd helps make an impression on both clients and potential staff.

“The building you're in can project to a client a good sense of your company. If they see happy, relaxed staff and look forward to visiting you, it can really help business. For a lot of companies if you have a building you're proud of you want to welcome people in like it is you're own home and that gives clients a warm welcoming feeling. It's a shop window for your company in a lot of respects. When people come out of university they don't want to go to a boring office, instead they can go somewhere that has a Belgian bar. These kind of things allow companies to stand out and be more attractive, it's not the same old stuffy office with wooden panels that looks like an old boy's club. It's like how people dress when they go to work, it's completely changed - a lot of offices are now more casual and it's not frowned upon. Everyone spends a long time at work, so it should be as nice as possible.'”
