You've asked in the right place - existing owners will always have a better grasp of the issues than legal advisors.
You have to ask what you are hoping to achieve - or more importantly, avoid, then decide the way forward. As a shareholder you do not necesarily have rights you think you have in relation to the assets of the company. You will all need to be directors, and one of you a company secretary, then you can decide who can do what. A limited company, apart from being expensive and fiddly to run, is a great way for one group of shareholders to muscle another one out.
The Articles would need some serious expert legal input to ensure everyone's wishes were satisfied. Looking at what other's have done won't answer your specific and unique problems.
A company limited by guarantee may be a better bet - that way you have members rather than shareholders.
But it's awfully convoluted. Why not become joint owners, or a partnership ? Then you all have full and equal rights. If you don't trust each other enough, then a limited company is just a vehicle for making things messy. I own one, not a messy one I might add, but that's becasue I'm the only shareholder!
If you think there are pitfalls serious enough to warrant using a company, then you should ask whether any form of joint ownership is a good idea?
