[Closed] Garden shelter - building your own, ideas please

I am looking to build a garden structure in my garden - somewhere to sit under during our fab weather ( to get us out of the house even more). Somewhere to give us shelter and cook/ eat alfresco.

Budget is a huge issue and to be honest I don't always think spending more gets you something special - its the sourcing of materials and the actual building of it thats more important to me.

So budget is £300 for a 10ft by 10ft structure. I can get 4 large oak 6x6 posts from a sawmill mate for £40 (to get things started) so just need ideas for structure itself, and roofing alternatives/ ideas really. Cheers
