The Boolarra Steel Frame House is an alternate method of framing a new house or build. It relies on the old post and beam construction principle. This very inexpensive completed steel frame and roof is the low foot-print structural backbone of the build. In this case the walls will be an infill of timber, cladded externally with fire proof compressed fibro-cement sheeting. The internal walls will be lined with some ply and some plaster.

The build is currently up to frame inspection stage. It is very interesting to view the ease of construction and enquire about the choice of building materials and fixings.

The house is designed to benefit from solar gain and the pleasant views. It was an early choice to remain off grid for all services although the grid power passes over the property. The area is prone to blackouts off grid is the short term electricity reliability & resilience insurance.

Experience has shown the heating and cooling advantage of living areas up stairs. This easterly oriented build benefits from 180 degree views of the Morwell River Valley, from Lou Yang to the hills of Mirboo North. The 4acre block is densely vegetated with native plants and trees, ( especially numerous large Spotted Gums ); this in itself is a beautiful feature to be enjoyed rather than destroyed.

Be advised that this house is still under construction. Please take care on site as there will be construction materials and tools around, we will make the site as safe as possible, be vigilant.

Sustainable materials
The nature of the strong steel post and beam building style makes for a very easy fix for the non load bearing wall framing. The sheer strength of the build will be lost to the eyes once the cladding is fixed. Ideally all of the wall framing could be pre cut and assembled off site, then carted to site for installation, making the overall build not only very quick but also very cost effective. Sustainability is a whole of build concept here not just sustainable products. Whilst the 2 shipping containers on site are quite butt ugly they do enjoy a very practical role on this site. Not only obvious storage but when separated then with a strong roof added these two beasts provide site water, shade, and a great spot for a fire pit in winter. Sadly the containers will be recycled back onto the market once emptied into the new build. The container's roofing , ie timbers and roofing are in fact to be re-utilised in the construction of sizeable shed on site.
