Variable offset of a curve

Sorry if this is already been discussed before but i cant seem to find a definite answer so would like for some help.

I have 2 curves which signify the top and bottom of a wall. i have set up a curve in the centre of these 2 curves to find the midpoint. I need to offset the centre curve in order to create arcs. I need to offset the curve by 1/3 the length of the line between the top and bottom (effectively the height). I just cant seem to figure out how to offset each point individually so that at the start they are only offset a little and in the middle they are offset a lot. Once i can figure this out i can interpolate the points into a curve and go from there. Any help would be appreciated

For one thing, you need to connect the 'IntCrv C' output to the curve input of 'Offset'.

But multiple values for the 'Distance (D)' input of 'Offset' results in multiple offset curves, not one curve that is offset different distances along the length.

I have only a vague idea what you're trying to do... Looks like fun but I'm short on time at the moment.
