| The original semi-detached house had already been
extended right up to the woodland border and had used up all its
'planning envelope' so the only further extension was to go upward.
The roof pantiles seemed in good condition, and
it was hoped that they would not need replacing. However, once the
scaffolding was erected the need to re-roof with breathable under-felt
became apparent. Most of the tiles were reused. The roof also had to be
cross-ventilated above the insulation to meet Building Regulations. |
