The first job was to remove the broken tiles from the old balcony. They were of an older style and had become unsafe. Then we laid a brand new layer of timber. To this we affixed the new GRP balcony that was then sealed. For the finished surface, we sourced interlocking anti-slip rubber tiles from Germany.
The original plate glass skylights had to be fenced off. The two new (and very heavy!) skylights were well worth the effort. The heavy-duty glass in the new skylights is safe to walk on.
