Here yo, the comrade of tabordiy also working on this project... Finally i found the way to this forum... we are still continuing the project and would like to share more pictures as finally the construction is growing...

(soon adding the pictures)
In the last month we renovated the ruin and added in some parts up to 1 meter of stones with a clay mortar.
This week we mounted the wood structure, the base square of the house on top of the ruin with help of friends. To position this square with the right angles we started putting already 1 pilar into place and we will soon add the other 3.
First we had to adjust the mortises we made in bent nr. II, as we made the calculations wrong, not realizing how to measure the knee-braces correctly at first (shoulder to shoulder).
As the ruin is about 2 meter high now and not easily accessible (having a deep ditch, former river) under it, we decided that we will not put the bents together and than mount the frame. We think to put the pilars at the 4 corners and then mount the beams on top on the spot.
To elevate the pilars we used a simple construction with a DIY hoist connected with a rope to a tree.
