Rain, rain go away

This is the view that greeted Peter as he arrived at the site


The long view-often what's needed!

The timber frame of the house, which extends up to be bolted to the roof timbers



The gabions at the western end of the house, where the bank isn't quite as steep

Actually, even though it's delayed the build, we can't grumble about the rain. It'll keep the aqifers nicely topped up.
Peter went to a site meeting on 14th August and sent me a message saying that the first sight of the timber frame in place was incredibly moving. The photo shows the view he had as he entered the site. The outlines of the upstairs rooms are emerging.
The meeting covered all sorts of details, including the passive venting system, external taps and drains, the balustrade to the front terrace, whether or not we want access panels for the plumbing of sanitaryware (no, thanks), how we'd like the floor to be finished, how the woodburner flue will get safely through the roof, where the warning/alarm light for the sewage treatment plant will go (don't ask; I didn't), how we will get electricity to the garage when we build it, etc etc. I keep thinking of my father, evening after evening, poring over drawings for the house he was building. As a child, I used to wonder why he found it all so interesting. Now, I realise, it must be in the blood.
The windows and doors have arrived at the builders' yard in Barnstaple, after a confused Latvian driver tried to deliver them to the British agent's premises, somewhere in Essex.

The really exciting July/August development is that we have decided upon a worktop for the kitchen and from that, Nathan can complete the kitchen design he'd proposed. The timber he sourced is from an oak tree felled 20 years ago and planked. The wood has been stored level and dry since then. The tree was about 250 years old and was in King John's parkland to the east of Bristol (hence "Kingswood"), reputedly giving the monarchs a clear route right through to London, without leaving their own estate lands. It is a "burr" oak; a most unusual growth and this ancient tree is going to provide a unique and beautiful work surface. I have to say that I was distinctly underwhelmed at the sight of the dusty, grimy planks but Nathan, his joiner and Peter persuaded me that it'll glow and that the revealed patterns will be really interesting once it's planed and finished.

The first fix electrics have been delayed, which is just as well, as there have been several frustrating attempts to get the wiring accurately on to the master drawings. Two sets of original, marked up drawings got lost in the post between Bristol and the electrician in Barnstaple. However, we have every faith in the electrician, who reassuringly says he won't do anything until he's sure we're absolutely happpy with it. The work can't start until the roof is felted and battened.

Earth-sheltered

This waterproofed wall will be covered up so that it's insulated by the surrounding earth. The builder is standing on top of what will be the kitchen


The store- and shower-rooms are snugly underground. This will be the third bedroom above them.


The gabions forming the retaining wall at the north-eastern end of the building. The stone is from a local quarry and seems to glow a real Devon red when it's wet


This is the hole where the stairs will be. Deciding on a curved stairwell during the difficult middle phase of the design and planning application process was a real boost to our morale. It will be top-lit by a rooflight and there will be LED step lights set into the lovely curve

I knew there'd be lots going on and decided to go down to the site one afternoon in early August. It was quite astonishing what progress had been made, despite July's rain. The house is taking shape and the rooms that will be underground already feel relatively snug.

Onward and upward


The final, defiant roots of the Macrocarpa, grubbed up and shoved ignominiously out of the way



These walls will be waterproofed and then covered by soil; this part of the house is effectively underground. The builder is standing on the ground floor.



In the background, the builders are making the gabion cages


This man was determinedly brushing away the rainwater which was collecting as fast as he could work

We attended a meeting in early July and then went over to see progress on site. Now that the slab was laid and the footings (deep, concrete "slices" cut down into the hillside, to act as anchors and stop the house sliding down), were in place and back-filled, the next step was the back walls, which will be carefully waterproofed. This co-incided with some rotten weather, which delayed proceedings somewhat but as the chief builder said, better to take the time and get it right than risk allowing water in through areas that are going to be effectively underground and inaccessible from now on. We agreed, fervently.
Interestingly, at a design meeting about 2 years ago (yes, this has all been going on a very long time), the structural engineer pointed out that the wonderful ruberoid rubber membrane that is wrapped around the structure would act as a grand sheer layer and there was the possibility that without some very careful design, the whole house would sledge down the hill. Hmmm. He re-drew it so that the membrane is wrapped around the anchors to prevent this. Jolly clever stuff.
The builders improved the shining hour whilst it was raining by making the galvanised wire gabion cages, under a makeshift shelter. The gabions are to support the bank at east and west of the house and will be filled with local stone. We also talked with the foreman about the slope immediately below the house. He agreed that it'll make a good vegetable garden and we'll enlist their help to level a wide terrace and help us to build raised beds. After all the angst about the original well, we realise that we'll end up with a well upsides of the house which can gravity-feed a pond via a rill ( always wanted a rill!). That well will need to be pumped out several times in the next few months, to allow the contaminants to wash out. It will never provide an adequate domestic supply, though.

Waterproofed

This is taken from the window of the site hut, a really good vantage point.

The waterproofing layer with a steel grid, on to which the slab will be poured.


We dropped in to the site en route to collect an anniversary present for ourselves, a framed photograph taken in 1978 by James Ravilious. He spent years taking photos of a dying way of rural life in this bit of North Devon; the villages and their inhabitants: Ashreigny, Dolton, Beaford, Chittlehamholt, Eggesford. His work began in 1972 with the Beaford Archive project and his photographs were one of the reasons why we chose this particular area. If you're interested to see his work, look at www.jamesravilious.com.

Water palaver, c'est fini

Steve checking out well 2


Well 2 is along the indistinct track used for the last 10 years or so only by badgers and foxes, beyond what could be Eeyore's house, in a very damp and boggy place


As we drove into Bideford in early June, to meet the architects, a message came through on my mobile to ring the well specialists, urgently. Surprise! The samples had indeed been mixed up; the water from the second well is fine, soft and slightly acidic (almost exactly the composition of the first well before it was lined) and completely safe to use. It'll mean a longer run of armoured cable but the flow rate (ie re-fill rate) is good and this well will provide us with a plentiful supply of water. Phew. I've promised that I'll leave the rest of the water-supply management to the experts but I'm really glad the quality was re-checked. As a bonus, we can drain the swamp at the bend of the track leading down into the wood, when a trench is dug for the well pipework.
The electrician and the plumber were at the meeting that day; an exhausting but really productive and interesting meeting. So many decisions to be made; such detail to consider. And we agreed a design for the staircase with the architects, after months of discussion. It all seems much more real, now and walking around the site later, in between rain showers, we began to imagine how the rooms will feel. Very exciting.

Well, well, well (or Water, water everywhere, nor any drop...)

We've had yet another roller-coaster few weeks. The well lining has indeed stabilised the shaft but it has reduced the volume of water to 1/9th of previous. We made a site visit in early May and talked to the site foreman, Joe, who'd been monitoring the re-fill rate. Peter did some calculations and worked out that the previous, vast reservoir which would have lasted us for about 4 weeks in drought conditions, has been lost. The re-fill rate from the ground source into the new, plastic-lined shaft has also been drastically reduced, so we can't rely on its refilling fast enough to provide more than a single day's domestic usage at a time. We were very cast down. However, about 100 metres away is another well, so we asked the well specialists to check its flow rate and send a sample for analysis. We knew it was a smaller well so the reserve would be less but it wouldn't need lining... We had the water analysis back last week and it is "unusable", with a pH of 9.6 , high levels of Aluminium, Ammonium and Calcium "off the scale", making it hard enough to fur up pipes in very short order.
This result is astonishing, from a water source within 100m of another which is slightly acidic, soft and un-contaminated. We've asked whether the anaysis returned may have been for a sample from somewhere else entirely, ie a lab mix-up.
There will be an answer (one or two options present themselves) but we will have to wait and see.
We're visiting the site in the second week of June, when we should have made a decision.

Anchoring and waterproofing

This is one of the concrete slices, cut deep across the hillside, to act as anchors, with its permanent shuttering.


The jumbled layers of rock , previously only glimpsed by torhlight, whilst peering down into the cavernous well shaft



By early May, the site had turned into a huge hole in the ground and the builders had created a relatively level plateau on which to work. It was hard to imagine, before we saw the process, how the house will be anchored in place but we are confident that it will stay put, having seen these deep concrete slices. The waterproofing is reassuring; it's a Ruberoid product and needs to be "signed off" by the company as being correctly applied and installed.
