that's just too vague a question and no sensible member of this, or any other forum, would risk giving an answer. You'd have to establish whether or not the walls are an integral part of the structure supporting the roof and then add reinforcing, in the form of suitable lintels, into the walls before removing them. Try looking at what the neighbours have done...these ex-council houses are often mass-produced to the same plan. If in doubt, knock the wall down at your peril, but better still, ask a structural engineer....just be careful!
