can you have a sliding kitchen door?

We've worked out if we changed our kitchen door to a sliding one rather than an opening one we could change the layout of our kitchen units and gain 2 base units and at least 2 wall cupboards.

Is there any reason why we can't have a sliding kitchen door? Are there any fire regs or building control issues we would stop us?

Yes, we've got a sliding pocket door, which passed Building Control regs. It's a solid door

Be careful if you have more than two floors in your property, as you might need a fire door on your kitchen if it leads into an area where stairs are.

My house hasn't got a kitchen door and the kitchen opens straight into the hall way. I only bought it 2 years ago so I assume anything like this would have shown up on the survey.

That's unusual in a home if it has more than two floors - does it have a sprinkler system installed ? Or other fire precautions ? In general, you need to protect the stairs and exit from bedrooms to outside , incase of a fire . ( in UK ) unless there's a protected exit to outside from a higher floor maybe ?

( I missed the 'more than two floors' bit)
