Windows
wooden windows
In the course of the renovation, new wooden windwows as well as metal windows were integrated.
On the ground floor of the former living and stable area: The windows were rebuild on the basis of the specifications of the heritage department. Furthermore the windows in the former living area were downsized to it's original size (in the course of previous renovations the window sizes were modified) . The reduced size of the window opening only had minor effects on the light conditions and is sufficient for the natural lighting of the building section used as a holiday apartment. On the upper floor of the former barn and stable area: New windows were installed in the new wooden wallboard.

ROOF
GROUND FLOOR
MEASURES TO INCREASE AIRTIGHTNESS
In the course of the renovation, the roofing was renewed (insulation in between the rafters and on-roof insulation).
The existing roof structure is preserved. The new and sinter fired roof covering is due to its red colourfulness closest to the original roof tiles. The existing tiles made of concrete were strongly weathered and derived from former renovation works.
