It looks like it falls about 3.5 overall, from SW corner to NE. DOes anyone have any suggestions on how we could retain it, and possible costs? Any help would be much appreciated. It is lot number 535 Like ⋅ Add a comment ⋅ Pin to Ideaboard ⋅ Re: Buying a Sloping Block 2May 05, 2020 12:50 pm juicy675 Hi everyone, I'm hoping someone can give me some advice about retaining a block I'm looking to purchase.

No footings required, Base width H/3 It's cheaper than cavity fill In that case this will be much cheaper. But he mentioned 2.5 m fall, so walls could be potentially higher?

No footings required, Base width H/3 It's cheaper than cavity fill thanks for the info, I'm a sparky so a little over my head. Do you think levelling of this block is achievable with a 1m wall? I've just had a mate of a mate take a look at the contours and he estimated about $40,000, 30,000 for retaining and 10k for earth works. Thats manageable, just trying to work out whether a level block is achievable or would look strange, or if there is a better option ie split level home Re: Buying a Sloping Block 14May 05, 2020 5:33 pm Split level is certainly an option in your case but that means you would still need to have a retaining wall passing through your split levels. But, in my humble opinion, nothing beats the views/grotesqueness of having house on top of 2.5m elevation. But to drive expectations right, it will be costing times more than $10K on earthworks as you would need controlled fill and therefore good compaction in layers, compaction testing, etc. Also, house like that will probably require underground garage, etc.

THe main reason we are looking in this estate though is no where else in the area has block as big as this, as we'd like a little bit larger than the usual modern backyard. If we can;t achieve that there probably isn't any point, as the views aren't anything spectacular. Would a possible option to be to retain the house area and have a lower backyard? My concern with that is if the neghbour behind builds a retaining wall to level their block we end up with a retaining wall either way. Re: Buying a Sloping Block 17May 05, 2020 5:57 pm Depends, you would need to talk to the neighbour. Retaining wall of 2m+ height won't be cheap for sure as it would have to be properly engineered, made from the concrete, waterproofed, etc.. I wouldn't be recommending building on a block with such slope unless you have a good view over there. Depending on which option you chose, you are likely to end up with $100K+ on the site costs easily here. What is the soil like? If it is a reactive clay, run from it.

Depending on which option you chose, you are likely to end up with $100K+ on the site costs easily here. What is the soil like? If it is a reactive clay, run from it. The soil is class A, all pretty much sand over here. 100k is a pretty scary figure, if it could run to that it wouldnt make it worth it, if that's the case we may have to wait for an established one to come up. As a backup option do you think any of the other lots may be worth taking a look at? Lots 540, 544, 545, 547, 551 are still available Re: Buying a Sloping Block 20May 05, 2020 6:43 pm alexp79 By the way, with this angle of slope, even with the split level you would need tons of earthworks. Personally, I would rather go with the smaller flatter block. Which smaller flatter block, Lot 528? or just in general I mean Give Jonathan a call. Tell him you know me. He is in my opinion the best surveyor I have ever worked with. His number is 0425 285 622 All the best Simeon 3 12406 i did click it, still couldnt make it out rofl. in any case, doesnt look like too extreme a slope, you may be in luck.
