A new doorway
Here is an example of a doorway built for convenience.
We built it by knocking down a section of the concrete block wall and fitting two lintels on each wall.
We fitted timber in the insulation gap, and dry-lined and plastered the block edges showing.
Then we fitted the door frame on the timber in the insulation gap and fixed the door on the frame, and did more plastering and finally painting.
