Nearing the end……

We’re past 90% now and the next few days will see the worst of the back breaking work completed.

The three pics above are a close up panorama of the house from the top of the drive. The tallest of these is at the finished height of 9 blocks.

Pic 4 above is from the front gate. Pic 5 shows the crane with the boom balance point now moved to extend its’ reach. A simple crate with rock acts as ballast, if we need to lift anything over about 60kg then we add more ballast to balance the crane. Pic 6 is the method of forming the lintel voids in the wall I devised. This shot shows the machined wood internals and the simple MDF sheeting externals.

Pic 7 is the insert ready to go into the mix. I fix them together with common sticky tape which holds together nicely and allows for simply cutting the tape as in Pic 8 to allow the internal wood to be removed. The MDF is then simply pulled inwards of the remaining void and we’re left with a nice clean resting point for the lintel as in Pic 9

Pic 10 shows the reach the crane now has to be able to lift molds into place to complete the ninth layer. In the foreground there are walls at level 7 on the left and finished height on the right. I’ve been trying to maximise the components I have to be able to set and pour maximum blocks for a days’ work which means not everything is done sequentially.

Pic 11 shows the foreground “skinny walls” at level 8 with 2 of the columns in the back ground at level 9. Pic 12 is looking down the back wall and shows the slightest of deviations from a perfectly straight wall. That deviation is over 30 metres and I’m quite happy we got it as straight as it is. Pic 13 is the front columns of the house and again, almost perfectly straight over the 30 metres. You can also see in that shot where we’ve used the imbeded threaded rods to fix “X” supports to to brace the walls. There have been several storm events where neighbours have recorded 90kph+ winds and the braces have held the walls very well under those stresses.

Pics 13, 14 and 15 are again comparisons over time of the same corner as the building develops.
