Wales needs to see a big increase in the building of smaller homes, according to a cross-party group of MPs.
It follows a warning that more people here are affected by the cut in housing benefits that critics call the 'bedroom tax' than in any other part of the UK.
The Welsh Affairs committee says those affected will find it hard to downsize because of the lack of smaller properties in Wales.
Sandra Charlesworth from Rhondda Cynon Taf says she will lose a quarter of her housing benefit, after her husband died, meaning she now lives alone.
She doesn't want to move somewhere smaller though, as her home is "my life, my heart, this is where my children come to - our life together meant everything, and it all happened in our home, my home is here."
