3 feet or $300 is the rule of thumb for needing a building permit. Not sure where you are, but it is a consideraton ;)

Assuming you have a concrete floor, there are expanding bolt anchors that will serve your needs well.

Get a masonry bit of the right size (probably 3/8 - 1/2 inch) and drill holes to the correct depth. Drop those little bugars in the holes. Thay have a pin that you smack a couple of times with a hammer, which causes them to expand within the hole and become firmly anchored.

Use treated wood for your sill plate. Drill holes to match the anchors you just put in.

When your wall is framed in, tilt it up into place. The floor sill plate will settle over the anchors. Drop on nuts aned tighten it down. Nail off the sides to the existing wall.

Next, if you need to put on outer sheathing, do that, or else put on your siding. Insulate. Sheetrock. Splatter some texture on it and paint.

You can get all this done in a weekend, but you may need help at a couple of points.
