Browse Forums Owner Builder Forum 1 Jun 26, 2011 11:46 am G'day people. I'm an experienced tradie who's owner-built before and will be building another house next year. This one will be a mass-on-the-inside / insulation-on-the-outside design for thermal stability using rammed earth or brick for mass (internall walls) and insulated steel/foam panels on external walls and roof. About 130 m² as there's just me to inhabit it. I know roughly what it should look like, but to save the work of the design and approval process I'm interested in buying someone else's design and plans, so if you can help out I'd be pleased to hear from you. Also, I want to find a steel section that can be laid flat on joists or bearers and then covered with concrete as a suspended floor in case I don't use a slab, so if anyone knows of one ...... (I know about Hebel stuff already). It wouldn't necessarily have to be supplied insulated as foam panels can be attached easily enough - I'm thinking of something like a heavy-duty trimdek-type section. It exists for commercial buildings but I don't know what it is called. Any info on steel/foam/steel panels available ex-Perth would be appreciated too. Thank you.

(Youll need them structurally engineered though, to suit your spans and loadings) Pat. Re: design for 33° south latitude WA 5Jul 08, 2011 6:30 pm Thanks Pat. I'm now thinking that a slab is going to be cheaper because rammed earth walls would need to be over 3m high (and therefore more expensive per m²) to allow for both a 2.7m ceiling height and a suspended floor. But now I know what "Bondek' is called.

SunM, in 99% of cases you will find the only person that can sell you the plan is the author of the plan. that being the designer or architect. be careful, dont want some homeowner flogging you a plan only to have the author of the plan hit you with a copyright infringement down the track. Re: design for 33° south latitude WA 7Jul 10, 2011 10:47 am Thanks architect - wise words. I usually have fairly different ideas to most people and this design will be another example of this, so I'll go through the usual process of giving my drawings to a drafty and structural engineer to turn into real drawings. I re-read my first post and realised that I didn't make it clear that my intention was not to save money by ripping off someone's intellectual property, but to be ethical and correctly pay the intellectual property-owner for a design that I liked. I just wanted to find a good plan and that's been going on for thousands of years I imagine. Well these guys are not looking good... I sent them a written enquiry last week and they have not yet replied.
