Being as a CEO doesn't mean much. If you have a bossy share holder, it will ruin your operation. I am currently in such a situation. I own 40% share, and the other company owns 60%, but I am the CEO. However, it doesn't mean much. It just meeans that you have the power to do the routine day to day stuff. Important decision still has to go through board meeting. Unless you can convince your share holders, you are out of luck. You can't do things that you like if the 60% doesn't agree with you.

Building a house take about 1 year. The most time consuming part is getting approval from the gov. It can take upto 2 years. Building the structure is cheap, the expensive part is the interior and the type of things you wanna use for your building.

Just my 2cents.
