This weekend we focused on laying the plywood flooring upstairs and putting in the floor noggins (we did not complete these all - there were a lot to do!). The 'smart ply' will form the base of our first floor build up.

Ductwork for the MVHR
The ventilation system is required to provide the background ventilation because we are hoping to make the building very airtight and therefore would not get enough from drafts etc. We also do not have any heating upstairs and are using the MVHR system to redistribute the heat around the house.
The MVHR system will supply air to the 'dry' rooms (bedrooms, sitting room, lobby etc) and extract air from the 'wet' rooms (bathrooms, utility room etc). By undercutting the internal doors air will move from the dry rooms (where it is being supplied) to the wet rooms (where it is extracted).
