Given the Earth's gravity you cannot build one, only simulate it.
For example in Vomit Comet airplane rides. These planes fly high up in the atmosphere and then they free fall in parabolic trajectories and people inside experience zero gravity for few seconds per fall. Such techniques are commonly used to train astronauts.
Have a look at the photo provided in the link and judge for yourself. You may want to buy yourself a ticket for a ride like this ;-)

No we do not have the technology to artificially manipulate gravity. That would require a quantum mechanical understanding of gravity, which we do not have. So even theoretically we don't understand it yet. On Earth astronauts train for missions underwater, the neutral buoyancy is a close analogue for zero gravity. You wouldn't need to do it though for long missions. You can simulate gravity simply by spinning the spacecraft at a few rpm. From a physics point of view being in a gravity well and simply accelerating in one direction are completely equivalent situations. Now obviously you are going in a circle but provided you were spinning the craft on a tether (perhaps using the spent upper stage as a counterweight) then the axis could be several hundred metres long, which is large enough that you wouldn't notice the difference in gravity between your feet and your head.

Not zero gravity, but micro-gravity....
First, build an air-tight room.
Second, launch it into orbit.
Third - habitate.

You build it inside the vomit comet... A NASA 7?7 which simulates 0-G by flying parabolic (freefall) trajectories. The can provide something like 0G for 30 seconds, but then must follow it up with like 3G for many minutes in order to regain the speed and altitude to repeat.

you cant earth has gravity.. so your room will also have it..
if someone could build it.. dont you think nasa would have one?

When you get it built, let me know!
