I believe the answer is:

igloo

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

'little house' is the definition.
'igloo' can be an answer for 'house' (I've seen this before). I am not sure about the 'little' bit.

I cannot understand how the rest of the clue works.

Can you help me to learn more?

(Other definitions for igloo that I've seen before include "Ice house for Eskimo" , "White House" , "Inuit abode" , "native dwelling" , "Inuit shelter" .)

I've seen this clue in the Evening Standard.
