We are going to straighten out our living room, the extension will be about 4x1.5 m and the house will thus have a straight facade. Since the ground slopes, the extension will be about 1.5 meters up. The base is rock. We are torn about which construction we should have. Either cast high pillars or set post shoes and pressure-treated posts. Pros and cons?
A deck will be built in front with slats underneath so the foundation will not be visible.
