The first concrete floors are down.
The biggest visual change on site so far. Damp-proof membrane has been laid over the compacted fill, and the ground-floor slabs are being cast section by section - the mixer ran all week, with granite, sand, and cement moving from the staging area straight into the floors. Two of the three homes now have most of their slab down; the third follows next.
The pipe sleeves you can see standing up out of the slabs are the plumbing and services routes, set in place before the concrete goes down rather than chased in afterwards. Slower to prepare, cleaner for the life of the house.
