The business world is going through a stage of evolution. In the last few years it has become less about suits, offices and water coolers, and more about hot desking, coding and caffe latte mochaccinos. More and more people are breaking the mould and creating companies and organisations that we thought we never even needed. To do that they need to exchange ideas, and some of the best places to do this are communal areas filled with like-minded individuals. There\u2019s nothing like discussing the realisation of your big idea over a craft beer. Check out below our list of free and cheap spaces for you, our hard-up innovators of tomorrow. London Campus Google has a network of spaces around the globe (including Sao Paulo and Tel Aviv) that offer free deskspace, internet and events to help provide budding entrepreneurs with the building blocks for their venture. The London Campus is located on Bonhill Street (in between Liverpool Street and Old Street stations), fresh coffee and healthy food is sold on site, and there are plenty of like-minded sounding boards to bounce ideas off. This is a great location, especially for those who like to network and slip their fingers into various pies. But, some have concerns that it is not in fact an ideal place to get your head down and work, for fear of being interrupted by the self-styled \u2018next big thing\u2019 every ten minutes. Worry not though, for there are other options. Ace Hotel lobby - Shoreditch Yes, a hotel lobby seems like an unlikely suggestion. And probably it\u2019s not ideal if you are looking for a quiet space. But, in all my working visits to Ace Hotel\u2019s subtly trendy lobby, I have not been interrupted once. You don\u2019t even have to buy a drink (although common courtesy would suggest you at least buy one coffee\u2014and it\u2019s good coffee too). Aaaaand you get free wifi. So I would say the name of this hotel is very apt indeed. The only danger is whiling away your working hours watching all the weird and wonderful Shoreditch characters swanning by, and taking note of any fashion advice\/disasters. Oh, and I should probably say, other hotels are available, apparently. Next! Tate Modern\/Barbican\/Southbank Centre and Festival Hall\/British Library For inspiration, where better to work than within the buildings that specialise in art itself. Galleries, museums and exhibitions all tend to have common areas where visitors can eat, drink and partake in high brow conversations about the spectacular piece of art they\u2019ve just happened upon. On the whole, these conversations do not stray above a few decibels, making these areas a very peaceful and rewarding place to work or meet with friends\/siblings\/parents\/business colleagues\/lovers\/study groups\/improv partners\/art aficionados\/magic circle members\/stonemason chums, etc. And when you need a break, rejuvenate your mind by wondering around the art installations that are conveniently all around you. Coffices Update: Coffices is no more. Another popular trend in London is the use of coffee shops by freelancers and other nomadic business people as temporary offices. As long as the place has wifi, a table and an electrical socket, workers will happily buy and attempt to slowly sip on just one coffee all day in exchange for a workspace. The trick is trying to keep that one coffee warm all day. Some extra fantastic news if you\u2019re aged 16-25 There exists an awesome organisation called somewhereto.com, which\u00a0negotiates free spaces for any 16-25 year old with a big idea, and then supports them in the pursuit of that idea. They have access to all sorts of areas, from studios, to galleries, to offices, to football pitches and to libraries. Simply sign up, find your desired space and contact them. They\u2019ll take care of the rest. And best of all? It\u2019s all completely free. So get out there and get innovating, you young people of today! Shared office space Unfortunately, and realistically, finding great free communal spaces is quite rare in London. But some are more affordable than others. If you are hankering for a hot desk, super keen for co-working or wishing for wicked wifi then this could be your only option. Some come for a price as low as \u00a320 for the day, for example the Oval Office, not in Obama\u2019s White House, but opposite the famous gas holders of Bethnal Green. Ok, that's it from me. All I can do now is wish you a happy and productive future of communal working (writes the 28-year-old sitting in his parents' kitchen...).
