I think i'd climb a tree and have a look at the lay of the land, see if there is a caravan park 300 yards away ? hills, mountains mean streams and water.
Finding a water supply would be my first priority.
Next shelter, somewhere nearby. No tools are required just sticks and leaves. And whatever natural resources can be put to use.
Having got a base its time for foraging. Food is top of the list followed by cordage materials. Obviously I'd keep my eyes open for any other useful resources, any flint, bowl shaped stones, clay, bones, litter (anything to hold water, or anything sharp)and started gathering tinder. I'd also look for animal tracks, especially around the water supply, see who else is living in the vicinity.
So hopefully i have located somethings i recognise to eat. :-? Beech leaves, hawthorn leaves, ramsons, blackberries, burdock, dandelions, reed mace, nuts.... I've collected some cordage material, rosebay willow herb, clematis, willow bark, pine roots, stinging nettles, wool..
Eat and make some cordage. I would be aiming at some strong cordage for a bow drill, so probably inner bark. I dunno if i could make any strong enough. Bow drill cord is a very tall order, but i have not managed a handrill fire (yet). Next more cordage, for traps and improving the shelter.
Time to go hunting. As many traps as i could set up. Fish traps and night lines for fish, snares and deadfalls for rabbit, pheasant squirrel deer or any other meat. I'd set as many as i could make hoping one would catch something.
The rest of my time is spent trying to get the fire going, pretty essential. Hunting, I'd find a throwing stick, gather some rocks (and sit in a tree above some regular tracks) make a spear and maybe a bow later on.
I'd also be fashioning things for around the camp to improve comfort. Some cooking pots to start with...
Once the traps are set and the fire is going the rest is largely keeping my moral up by keeping busy.
Thats my Bushcraft answer, in reality i would probably try and walk out.
Head in one direction, and hope to find civilisation within three days. And if this is the UK then we're never that far from civilisation. Or I'd get found by a dog walker cold hungry and naked.
Ideally ( i can dream can't I) by the time someone arrived the log cabin would be finished, I'd be dressed in buckskin and wool and there'd be larder full of smoked meats and fish and a productive garden underway :-D
