improvement

I have a wooden cabin / garden room which is getting fairly old and I am thinking about extending its life by rendering the outside of it, insulating it and changing the wooden doors and windows to UPVC. Has anyone done this or does anyone have any advice?

I've just moved house and my new home has an existing driveway which hasn't had some tlc for a long time. I got some quotes for redoing it but these are astronomical so I'd like to see whether I can have a go at improving it myself. With this in mind I wondered whether anyone had any ideas how...
