@fkamiah17 my suggestion would be a hall of residence. A bedroom/office for each member and every so often a small kitchen dining room. They have the HOC restaurant for other meals. Other than that, they have their actual home which is presumably in or close to their constituency. If they choose to live a long way from that then that's their affair and the cost is down to them. No second home allowance or flipping or tax breaks.
