The problem with the house was that the kitchen was too small. The owners enjoy to cook but were limited by the space. The solution was to knock out the external walls by 2 metres and extend the roof to make it look original. We installed bi-fold windows and a bench for an outdoor servery.
The clients wanted to reuse as much of the old deck as possible so we used the existing joists and decking. Bearers, pole plate and posts were replaced to specs. It was tricky work threading nine metre long steel posts through the deck. The only way this could be done was through mechanical means. The council was also involved with sewer modifications and inspections to approve the renovations of the pre existing deck.
The one thing with building is that your day finishes when the task is completed. Sometimes it is not worth while doing a few hours the following day. You always need to ensure that there is integrity in the structure and you need to ensure that the site is safe before you go home. This is just common sense but it is also legislative now. So here we are a twelve hour day.
