"We will now be claiming 20% in lieu of 25% at stage 3. Where we will have completed all wall framing. At Stage 4 we will now claim 25% in lieu of 20% where brickwork and 1st floor roof trusses will be complete."
Yes same for me. I believe they are just doing the roof after the bricks. I've seen a few double story homes both from Wisdom and Masterton that start the bricks before the frames of the roof have been put up.
