This week we visited the site of a renovation and extension project on a post and beam house in Frankston. The house is double storey, with the main entrance on the second storey as it is built into the side of a hill. The lower storey is where the extension is occurring while internal components of the upper storey are being redone. Features of the renovation - Renovated upstairs kitchen/living area with bathroom and study - U-shaped kitchen - Use of existing roof and floor

- Timber spiral staircase Existing studs positioned around 1200 centres apart
- New downstairs extension Construction systems Timber stud wall frame
New steel battens installed
- Existing timber studs installed when house
Existing pole foundations
was built in 1978 spaced at around 1200mm
- Pole foundations are used as the house is
apart. However, distances between individual
located on a steep slope.
studs are not uniform.
- They are beneficial as they are less disruptive
- New steel battens spaced at normal distance
to natural features and existing drainage
of around 450 – 600mm apart attached to
patterns on the site (Ching, 2008).
existing horizontal studs enable simpler installation of insulation and plasterboards. See Figure 1.
Existing exposed timber joist roof - Sloping double timber beam spanning entire ceiling supports joists which cross the beam at angles. - Joists are connected to beam using notches combined with through-bolts. The thick members require four bolts for adequate strength (Ching, 2008). See Figure 2.

Structural and aesthetic materials Timber - Oregon used as double roof beam and joists: high strength to weight ratio (Just Wood Australia, 2013), non-waterproof - Silvertop ash as ceiling linings downstairs: moderately durable, good fire resistance (WoodSolutions, 2013). See Figure 4. - Timber finishes on joinery Red PVC piping around electrical cables for aesthetic purposes
Figure 2 Notch connection ensures rigidity (Harris, 2000).
Cantilevering I-section steel beams - Supporting upstairs balcony - Wooden poles originally supporting balcony sawn off as they are unnecessary due to load of balcony being entirely supported by steel beams. See Figure 3.

- Timber finishes will enhance the “Bush Regionalism� style of architecture by reflecting the materiality of core components. - Exposed timber combined with views of and exposure to natural surrounds via large windows and balconies utilises the comfort brought by the natural landscape. See balcony in Figure 5.
