Outbuildings: 2026-01-22

While almost all of the building work was completed before the end of 2025, there were a few items outstanding which have been attended to over the past couple of days:

  • The rainwater drainage inspection chamber in the North-East corner of the Courtyard (top-left of the overview photo) has always been holding 30-40mm of water – implying an inadequate ‘fall’ on the outlet pipework.
    • The fall was checked with a laser level on Tuesday, which confirmed the chamber was set at the right level and pointed to some sort of issue on the downstream pipe run.
    • Excavation of that pipe run showed there was a ‘hump’ in the pipe which was causing the issue – partially due to it passing over a separate underground pipe connected to an Aco doorway drain.
    • With the pipe run re-routed away from the other pipe and re-levelled at the correct fall, the rain is now draining out of the inspection chamber.
  • The ground in the Courtyard has always been prone to holding pools of standing water – which was evident before construction started. As a consequence, a network of ‘land drain’ pipework was installed, formed from four ‘legs’ running east-West (which will end up in the middle of future planting beds).
    • The expectation was that there would at least be no standing water in the immediate vicinity of those land drains – but that wasn’t the case, and in fact there were some pools of water directly above the drains.
    • The issue turned out to be the use of solid clay as the back-fill material over the land drain pipes – and in some cases inadequate pea gravel over those pipes.
    • The agreement with the build team was that they would remove the layer of clay overlaying the land drains and top-up the pea gravel cover over the pipes to the specified 100mm depth – and then I will fill the trenches with some more free-draining soil from elsewhere on the site, as part of the work required to prepare the soil between the drains for planting.
  • Some other finishing touches that happened to be scheduled for today were for the windows and doors.
    • One of the window handles was from a faulty batch, and the lock cylinder kept falling out – so that handle was replaced (from a new, good batch).
    • There was some install-time damage to one of the door handles, which was also replaced.
    • The original window sills turned out to be too ‘deep’ to fit properly so those were re-made and fitted today.
    • A minor manufacturing defect on the bi-fold door meant the bottom seal had been torn – and would be torn again if one of the hinge fixings wasn’t adjusted, so that hinge was re-fitted and the seal replaced.

Car Care Facilities

A day of dry and not-too-cold weather provided a long-overdue opportunity to wash the worst of the building site mud off the BMW i3 and to give it a coat of Autoglym Extra Gloss Protection to try to stop it getting too dirty too quickly again over the Winter.

The outside space works very well for washing the car, with two outside taps (fed from the rainwater harvesting tank) and the permeable block paving draining the water away.

Even with the boot and bonnet open the car still looks small inside the garage, with plenty of room all around for access – and scope to accommodate much larger vehicles. (The i3 is exactly 4m long whereas larger estate cars can easily be 5m – but the garage is more than 6m, at the insistence of the original Architect.) The lighting works well, with four pairs of outdoor-grade Philips LED fittings – each pair being switchable independently. Each light fitting draws 42.9W so that’s 343W if they’re all on – which seems like a huge wattage for LED lights but the illumination level seems about right (and will improve once the walls get painted white).
