Outbuildings: Week 31, Day 1

Installation of the Aco threshold drain channels at the four Garage Door openings, connecting to the underground pipework installed previously – together with some more preparation of the foundation for the block paving (including the delivery of a further lorry-load of stone).

Note there’s a gap between the Aco channels and the concrete floor slab, where there was previously a row of blue engineering bricks – with large vertical holes – which acted as the ‘shuttering’ for the concrete floor slab. The roller shutter Garage Doors will sit behind the brickwork openings and it seems better to have more concrete in that gap, rather than some of the block paving.

There was also further work in the Courtyard, back-filling around the rainwater harvesting tank enabling the adjacent drains to be connected up and taken further to the West.

Rainwater harvesting tank now back-filled with pea shingle and connected to the incoming rainwater pipe (running diagonally) – with the pipe from the Courtyard’s doorway threshold drains visible on the right.

The first eight of the reconstituted stone steps for the external staircase were also delivered, ready for those to start being installed.

Following the delivery of a further 50m of 75mm-diameter ventilation ducting on Friday, the three ‘Extract’ vents were connected up to their above-ceiling plenum chamber, enabling the installation of the remainder of the loft insulation to proceed (once some further insulation is delivered).

Outbuildings: Week 30, Day 4

Installation of the shower drain which will be integrated into the wet-room floor covering.

Also good progress with the airtight tape around the perimeter of the plasterboard ceiling in the Workshop, helping to provide a long-lasting airtight seal preventing air leakage into the roof space. (The idea is to restrict the air movement to happen via the MVHR unit’s heat exchanger, avoiding uncontrolled leakage elsewhere within the building fabric.)

The rainwater harvesting tank was delivered mid-morning, enabling its dimensions to be checked and the hole for it (that had been started yesterday) to be completed. The hole is roughly 2.5m wide, 3m long and 1.75m deep.

The threshold drain channels for the Garage doors were also delivered, and some more of the spoil from the landscaping in the Courtyard was removed off-site.

The electrical team were also back on site for the first time in about 10 days, continuing their first-fix in the two-storey section at the West of the building.
