Hello Cecil, NO !! monies should change hands till the extension is built up to floor height and then the payment will be based on the work carried out. I would then suggest a payment when the roof is on and the finale on completion. I strongly suggest your quote includes materials how els will you know the full cost. I would also keep 5% back from the last payment for 3/6 months. Make sure all this goes in your contract. Regards Michael
