Building an extension Part 6 – Installing joists and steels

In Part 6 of The Extension series, which follows the build of a side and rear extension, we see the joists and steels slotted into position in preparation for the removal of a load bearing wall at the back of the house.

The wall is being knocked out to extend the existing kitchen and create a kitchen/diner on the ground floor and an additional bedroom on the first floor.

This episode includes:

  • Cutting joists to fit the steel beam
  • Spacing the joists out with noggings and the challenges associated installing joists and steels.
  • Using Strongboys to support the outer and inner skin at the same time
  • Trimming the existing floor joists so they can sit in the web of the steel beam
  • Cutting out the brickwork
  • Lining up the holes of the two steel beams
  • Bolting timber on to the steel beam for the jiffy hangers
  • Expansion joints
  • Insulation
  • Using jiffy haners/joist hangers
