I am a type of room you cannot enter or leave. Raised from the ground below, I could be poisonous or a delicious treat. What am I?

Pronounced as one letter,
And written with three,

And two only in me.
I am double, I am single,
I am black blue and grey,

And the same either way.

Remove the first and last but I am the same
Take out my middle and still, I remain.
What word am I?
