Browse Forums Owner Builder Forum 1 Oct 05, 2010 9:59 am Hi Everyone We have just purchased a large block of land which we have proposed to subdivide with a builder. Our portion of the land is 1300sqm at the lower end of the block and we intend to do owner / builder with guidance from our builder friend. Does anyone have any advice on retaining walls, cladding, and planns for a very steep incline? We are at the planning stage and would love to hear from anyone who could offer us advice when it comes to steep slope builds. We will have sweeping north facing views over the Barwon River which is the reason we have taken up the challenge of this very steep block. We look forward to hearing from you.

I have a very gentle slope house size of 441sqm on steel piers slope is 400mm one end and other end is 2.5 metres cost of steel flooring system including engineering 49K hope this helps.

Not too difficult as long as you do not fight the slope too much. I did 3 cuts with 45 degree batters and built a series of platforms using steel columns, mounted on concrete piles 500 mm out of the ground. Hardi plank sheeting with a zinc skillion roof. If you have space and reasonable soil, batter the banks under the house to 45 degrees and you do not require retaining walls. If you still require retaining walls and have space, then tier them no higher than 1 metre some 1500 apart and you do not require engineering approval. The Light Steel Beam company have steel bearers that span much longer distance than timber on steep land and reduces the amount of footings you need if you are looking for a 'wow' factor. The steel is more expensive than timber, (though for big spans, same or better cost) but when you work out the cost savings in less piers, in often difficult terrain, the cost is soon re-covered.. see ...http://www.litesteelbeam.com.au/liteste ... _view.html Good luck and enjoy the ride.

Regards Heath I think that was very great project, building on a very steep slope. Well, for me it is better the filled is a concrete. Yeah, it is more cost for that project but I think result was very great.

My advice would be design the house to follow the fall of the land to reduce exavation cost we have used a combination of slab & stumps, use light wieght material like colourbond & hardies cladding products which will reduce the wieght of your build, and remember to think outside the square.

We are cutting into the site to build in a basement/garage which will result in high concrete filled retaining walls, but we feel it will be very useful space and worth the cost. Luckily our soil is stable but we did need to get a geotechnical engineering report to OK it for council and building. I'll let you know when we get a quote for the cost of the walls :p Hi All It has been a few weeks since my last update. The build has been progressing well. No major issues to report.
