a S T A M M E R project 2008 November 8 & 9, Saturday & Sunday The abundant rainfall has stopped and the
temperature has dropped. It was about 5ºC in the early morning this
weekend. |

Work
continued on the roof structure. The roof beams will have to rest on
the ring beam, with supporting braces that give the roof an angle of
5º. This angle of 5º (=9%) is ideal for a vegetation roof offering
sufficient drainage without much risk of soil run-off.

Braces on the south facing ring beam. They
elevate the roof 38 cm to give it a slope of 5º. |
South-west corner, looking
north. Notice the 1.8 cm space on the ring beam on the left that will allow for supporting OSB board. Saturday 15:02 |

The braces are joined and covered by OSB board. This will not only offer the supporting layer for the earth plaster but also strengthens and fixes the braces. |
The roof beams sticks here 65 cm out from the wall. That should perhaps have been longer but we couldn't get beams longer than 5,7 m. Looking north-east. Sunday 14:21 |
A Blue tit on the feeder with almonds on top and
peanuts below. |
We activated the bird-feeders again, as we did last year. They are really popular with the birds, although the species interested are limited to the Blue tit (Cyanistes caeruleus) and the Great tit (Parus melanolophus ). They are especially fond of peanuts and (home-grown) almonds with a slight preference for the latter. We offer sunflower seed in another bird-feeder where they can actually take out the whole seed and carry it away (which offers of course less of a show for us). |
