We decided to add a ‘feature’ to the Great Room by exposing the rafters where they run in front of the Conservatory Extension Gable wall. We are going to continue the room walls up to the roof of the Conservatory extension and keep the roof exposed on the inside. This will form a ‘Dormer’ niche, this allows viewing of the rafter size and illustrates the depth of the main roof.
To this end we insulated the external wall to about 200mm depth

Then framed the extension of the wall up to the roof. We then need to extend the roof surface of the extension the inside of the main roof. We was a little tricky because there was not much depth to align thing with so we fixed a strip of Osb down the roof to get an alignment then fitted noggins between the rafters.

The noggins needed to have a complicated compound cuts to get them to align correctly which took quite a lot of ‘trial & error’! We finally got them cut and glued in place.

We initially made the 3 sections each side of the centre then looking at it decided we had to make the last sections as well.
