The Countdown to 2012 campaign has even gained celebrity support. Check out the stars below who are backing the campaign for more affordable homes in Scotland.

Dennis the Menace

'My treehouse is brilliant! No, it's better than brilliant. It's fabu-tastic! It's in the big tree in my back garden and it's where me and my pals go to get away from boring adults and have some fun! It's got different levels where we can play music, come up with great fun schemes and just hang about. It's even got a moat to keep oldies away! It's the best treehouse anywhere in the world EVER! Don’t you wish you had one just like it?'

You can catch Dennis and his treehouse in the brand new Dennis and Gnasher TV series, CBBC weekdays at 3.45pm.

Kenny Logan, former Scottish international rugby player

'We need to tackle the gap between the thousands of people waiting for a house and the lack of affordable homes – which is why I am supporting Shelter Scotland's campaign. The Scottish Government's commitment to give everyone the right to a home by 2012 is something we should be proud of and strive to achieve.'

Marti Pellow, actor and singer

'Everyone deserves to have a place over their heads that they can lovingly call home.'

Greg Hemphill, comedian

'A house is where you live but a home is where you love.'

Karen Dunbar, Scottish comedienne

'I am proud to support Shelter Scotland's campaign. The more people who are aware of the need for more affordable homes and the 2012 homelessness commitment, the more power we will have as a nation to ensure this promise is met. This would dramatically improve the lives of so many Scots currently without a home to call their own.'

Rory Bremner, comedian, is also supporting the Shelter Scotland campaign.
