the first Certified Passivhaus in England, by Seymour-Smith Architectsthe AI PassivHaus

1st February 2010

The contrast between the smooth plastered walls and the texture of the Lignacite blocks and the precast ceiling panels is starting to look great.

The next process is to spray several coats of a light filler (StoLevell In C) throughout...
It’s an excellent fast system, sprayed by an airless machine, almost like painting a car. Because all these products are solvent free, there’s no smell, even in this very airtight house.

However, drying the stuff in a super airtight house is quite a conundrum!

But after lots of window opening and closing, heating and dehumidifying, the persistent team from P3 have finally got the better of it, and most of the house is looking wonderfully crisp and white.

It’s difficult to show in a photo, but we’re thrilled with the final effect of the levelling coats and paint on the Lignacite blocks in contrast to the smooth plaster on the Ashlite blocks.

And the outside is white again too – oh, joy.

Robin is back, digging the trench from the house to our borehole and lowering the driveway to its final level

although this of course creates more rocky spoil to have to spread elsewhere...

and inside, Graeme is able to crack on with the electrics, now that most of the painting is complete. It’s all entirely the wrong way around of course, but having all of the services exposed does mean we’ve had to re-write the rules somewhat.

Robin and Les gather up all the lovely Polystorm crates which have been so useful around the site, and bury them to form our stormwater soakaway.

R.I.P. Polystorm crates...  (shown here wrapped in geotextile, ready to be backfilled with clean stone)

Inside the house, the guys from P3 are finishing off – although the rest was spray applied, the top coat of paint is applied by roller, so that we can make good without the texture being different. This is no ordinary paint though – it’s StoClimasan, which, believe it or not, is odour-eating paint!

Now that the driveway surface has been brought to its final level and a trench dug from here into the building, the guys from Filterclean have come to commission our borehole.

It’s very pleasing to see a good amount of nice clean water coming out of it – although it smells quite eggy to begin with, so we are left to pump it for a few days to see if that improves.  A sample will then be sent off for full analysis.

Chris has a fun day unwrapping the ventilation ductwork, now that the decorating is finished...

and we’re pleased too with the first of our cable trays. This aesthetic may not be to most peoples’ taste, but we’re thrilled with how it’s starting to look.

Another exciting arrival is our wood stove. This has a minimal heat output to the room (1.2kW), but will give a hefty 10kW to heat out hot water in the winter. In an airtight passivhaus like this, it is important that it’s room-sealed, with a ducted combustion air supply from outside.
