The evidence for this building in the original consists of a chalk floor with a hearth but no stake holes for the walls. This means that any structure that we build has to leave no trace.
The different thatching styles used.
The main structure consists of larch rafters with woven hazel ringbeams. One section of the building is completely woven hazel, this provides a base for the grass thatch to fix to.On the other sections we have experimented with different thatching materials and methods, with most of the thatch on the roof tied on with willow.

A floor has also been laid in the building made from crushed chalk.

With the end of this phase of the project in sight, and the buildings almost finished, we thought it would be a good idea to dedicate the next few days blogs to each building.

This building has been used to test a lot of our construction theories. A different method was employed in each quarter of the building. Two sections of wall were woven with a diagonal weave and two were woven horizontally.
The doorway in the south wall. Two different weaving styles can be seen.
The roof was also divided into sections which allowed us to experiment with rafter placement, ways of attaching the ringbeams and different thatching materials.
the different thatching methods that we tried.
We also used this building to test our daub material before we used it on building 851.

We have been working on all three buildings today.
On building 848 we have been learning to thatch in a more traditional method, by tying the thatch to the roof. This is the first time that any of our volunteers had thatched and the results were very good, and to make things more interesting, we were also tying the thatch on with willow.
Tying the thatch to building 848.
With building 851 we have been continuing with weaving the roof. We have also re-tied the ridge pole and adjusted the rafters, creating a more symmetrical roof.

We took the birch rafters off of building 547 as they weren’t quite long enough to give the roof pitch that we need. We have replaced them with longer larch poles and are now going to test different construction methods on the quarters that we have created.
