Get a Scot to build homes (8)
I believe the answer is:
cottages
'homes' is the definition.
(I know this)
'get a scot to build' is the wordplay.
'to build' indicates an anagram.
'get'+'a'+'scot'='getascot'
'getascot' is an anagram of 'COTTAGES'.
(Other definitions for cottages that I've seen before include "Small house in village or countryside" , "Small single-storeyed dwellings" , "Get a cost, oddly, for the small houses" , "Small one-storied houses" , "Small single-storeyed houses" .)
