ive never heard such crap! What is all that bollocks about 2 up 2 downs not being big enough ?!? And no one wanting to live in them.
It's bollocks - The biggest growth sector is single households.
And I have a family in a two up two down - a small 250k terrace cottage in the south east. If it's good enough down here why would I not live in one oop North 
And those houses were nicer and bigger than mine - 14ft wide Edwardian frontage instead of my 10 foot wide house.
