Idd, and www.slackiller.com , all of which are very easy to follow if you go step by step.
And this sounds like it'd be hard to make it look good unless you are quite a good mapper, as creating a road in a forest isn't gonna be easy, think about the trees, the ambience, I say have the road sunken down into a small "ditch", and have trees hanging over teh road, so you can let some sunlight through. Get de_predator.wad (csbanana - google it) to get a great couple of textures for a forest canopy.
The houses should be at right angles to each other, and have them on opposite sides of the road, and allow the CT's to approach the house from.. say.. a "sewer" or a river; you could even have one of the houses have a big spinning water wheel type thing, not 100% original, but would look nice.
Yeah, I have no more ideas. Bye!.
