Local authorities, the MOD, government departments have been selling off oodles of property in recent years in a bid to balance our collective books.

Wrecks was produced at the Geffen Playhouse, Audrey Skirball Kenis Theater in Westwood, California in February and March 2010, with Ed Harris again playing the role of 'Edward Carr'. The plot centers around a man, Edward Carr, coming to terms with the death of his wife, and the dark secret that brought them together. The agent or developer is no longer a member of rightmove.co.uk. The link you have used is incorrect (this is most likely if you have copied the link into your browser.

Good news for anyone wanting to pick up cheap property for redevelopment, albeit it most of the sell-off is likely to be to the benefit of remote developers rather than local communities.
Here is the (updated 2019) links list:
1. Firstly (and many thanks to Wreck reader Tina for this tip-off) the government has launched a government property search tool. Currently in beta and mostly seems to be bringing up local authority sell-offs at present, but a brilliant tool for anyone looking to see what might be available in a particular location. Try it here.
There's a similar tool for government properties available to let here.
And a nice-looking tool (maps ad everything...) specifically for selling off all those 'surplus' courts and tribunal buildings in the UK - here.
2. MOD properties. Basically, property sales used to be handled by Defence Estates, who produced a basic list. Reorganisation put Defence Estates into the pan-departmental Defence Infrastructure Organisation (DIO) and it's got much, much harder to find out what is, or is about to be, on the market. Information should be listed here - in the Disposals database - but it hasn't been updated.
3. UK-wide auctions/repossession

4. Local authority property for sale. This varies from local authority. Some, like Cornwall Council, publish lists of property for sale online. However, mostly you have to contact a particular council's Estates Management team which is responsible for the disposal of land of property, including farms in rural areas. But my suggestion would be that you first try the beta search tool, mentioned at 1, to see if anything comes up in your area.
5. Similarly, property for sale by utility companies may be listed on the company's own website, but most are put up for sale or auction through preferred estate agents (eg South West Water). You basically need to find the right links and keep checking. This link (also sent by Tina) goes to a helpful list of which water company covers which areas.
The National Grid's property for sale list still exists, but the Coal Board (as it was) has been swallowed up by a new government department and no longer holds a list.
The Canal & River Trust (used to be British Waterways, relaunched 2012). The charity has its own property team who can give information and advice about empty waterside properties that may be available. The Trust's public notices page mostly lists boring legal notices but land and sale notices are sometimes included.
7. If woodland rather than waterside is more your thing, here's the information page on Forestry Commission property for sale in Scotland. In England and Wales things have been rearranged and it's now pretty impossible to find out what land may be for sale - presumably sales are no longer being handled by the forestry guardians.
8. Guidance on buying empty homes - The Empty Homes charity and in Scotland, Rural Housing Scotland is similarly campaigning for and helping people to live in depopluated rural areas.
SPAB - the Society for the Protection of Ancient Buildings has lots of information on renovating older properties.
9. And, not exactly public property, but the Church of England publishes an online list of closed churches available for disposal - Closed churches and the Church of Scotland lists churches and other church property for sale on this website.

Inciting Event: Ralph crashes the party in the Niceland apartments feeling left out of the festivities. He argues with Gene about their life in the apartment vs. living in the dump. Gene says he could live in the apartment if he won a medal, so Ralph vows to win a medal.

First Plot Point: Ralph fails to show up in the game when the arcade opens. The arcade owner puts an out-of-order sign on the game, so Fix-It Felix must return Ralph to the game before it’s unplugged and hauled away.

First Pinch Point: Vanellope uses Ralph’s medal as the entry fee to get a position in King Candy’s race.

Midpoint: Ralph teams with Vanellope to build a cart and help her learn to drive well enough to win the race so he can get the medal back.

Second Pinch Point: King Candy convinces Ralph that Vanellope is a danger to everyone. Ralph destroys Vanellope’s cart and tells her she’s wrong for wanting to race in the game.

Third Plot Point: Ralph sees Vanellope’s image on the side of the Sugar Rush game and realizes she’s not the villain but the hero of the game and heads back to undo the damage he’s done.

Plots And Wrecks France

Climax: Ralph battles King Candy/Turbo (who has become a Cy-Bug) on Diet Soda Mountain. Ralph causes the Mentos mountain top to collapse, and as he falls among the Mentos to certain death he clutches the one medal that holds meaning for him: the one made by Vanellope.

Climactic Moment: When the Mentos hit the soda inside the mountain a huge beacon is sent skyward. King Candy/Turbo can’t refuse the Cy-Bug nature to rush toward the beacon. He’s vaporized by the rushing hot soda.

Resolution: Vanellope is revealed to be the main character (a princess) in her game. She takes her place in Sugar Rush, and Ralph returns to his game, satisfied with his place as the bad guy.
