[01] IN SITU
The stumps used were concrete, however, they had a steel rod running up through the structural element in order to fix it to the bearers above.
[5 Gardner St, Box Hill]: There is a clear distinction between the existing structure and the extention at this stage of the build, however, these structures will “marry together” through the same detailing and the same materials. The existing house had two timber skirtings which meant it was flush up against the earth. This posed problems in terms of the lack of sub-floor clearance that is crucial for cross ventelation
The excavated land spoken about before is visible here, so too are the multiple stumps which support the structure.
Insulation is seen to be installed within the timber floor frame. Breather sarking paper is visible here too, a material that is used to wrap the wall framing in order to stop condensation and moisture from entering the building.
The stumps were capped in order to prevent termites or ants from penetrating and infesting the timber framework. Metal Rod (used to fix stump to bearers)

To connect each truss component, purlins are used.

[5 Gardner St, Box Hill]: There is a clear distinction between the old and new roofing tiles. The old tiles are much more brittle as they do not contain any plasticisers like the new cement tiles do. Hips

NOTE: Roof was pitched at 25 degrees

Internally, the ceiling trusses were exposed, showing the joinery of the timber. Truss plates have been used in order to reinforce the connections between the beams and rafters.
Top plates are a timber beam that distributes the load from the roofing system into the timber wall framework and then to the ground. The timber trusses were assembled in sections onsite before being fitted to form one structural element.
Top plate
Wall studs
Bottom plate
[01] IN SITU [5 Gardner St, Box Hill]: In terms of wall systems, a traditional timber stud frame wall used. This consisted of the top and bottom plates along with the studs, as mentioned before, but also with noggings that are fixed horizontally between each stud.
Top plate(s)
Noggings
NOTE: 1 x top plate = non-load bearing 2 x top plate = load bearing
Wall studs
Bottom plate
Refer to the wall system diagram: The noggings are staggered as it makes it easier to use the nail gun to fix it to the structure, that is, there is nothing obstructing the use of tools. Secondly, they are staggered based on the size of the plaster sheets that are used to brace the wall frame.
Plaster sheets are able to be fixed to a nogging and a main plate (top or bottom)
Up-close view of the noggings and the staggered levels they are fixed at.
In terms of interior flooring, tongue and grooves have been used to create a perfectly joined surface. The tongues slot into the grooves in order to create a surface that is flush and smooth.
The details both inside and out are going to continue in accordance with the existing structure. The builders want to “marry� the existing building with the new extension and make it look as though they are, and always have ben, one structure.
[01] IN SITU [5 Gardner St, Box Hill]:
[Site Progress Summary] The required framework for the structure has been established, however, it is still exposed. In the next week the stumps for the decking will be put in place, along with the waterproofing in the wet area.
