The joiner has started to reinstall the first floor. It is around 30mm higher than the previous first floor. This provides us with more headroom downstairs and this makes up for the fact that we will be installing underfloor heating throughout the house. Downstairs (due to the existing cellars) we had no option other than to put the underfloor heating on top of the existing floor. This raises the floor height by 120mm. Lifting the first floor by 30mm partially compensates for this, while having little impact upstairs as we are going to leave the roof beams exposed.
There are two main beams made of green oak in each of the downstairs rooms. Joists are attached to these using hangers and are then attached to a wall plate that has been glued and bolted to the inside wall. The joists are attached to the wall plate using hangers.
