Claimed for building and home; it could be beside the point (7,5)

I believe the answer is:

decimal place

I'm a little stuck... Click here to teach me more about this clue!

'it could be beside the point' is the definition.
The definition suggests a singular noun which matches the answer.

'claimed for building and home' is the wordplay.
I cannot quite see how this works, but
an anagram of 'claimed' is 'decimal' which is present in the answer.
'home' could be 'place' (synonyms) and 'place' is found within the answer.
This accounts for all the letters.
This explanation may well be incorrect...

Can you help me to learn more?

(Another definition for decimal place that I've seen is " Position of a digit to the right of the point".)
