I haven't heard about this.. only max H of such a thing no more than 4m in wales. Sounds like the groundscrew is the right thing for the job to me, & hopefully that £900 can be totally slashed! Im all www'ing tmrw on where/ cost etc. Excellent help- so grateful chaps. Btw- is this a decent place to ask about a neighbour dispute re. a flippin great big tree? asked on a gardening forum (& this base Q.. all snooty tooty noses in the air dericate frowers those lot! urgh).

Hi PeterW.. please explain a Rebar? hole borer > concrete fill.. along with groundscrew ideas: make SO much more sense to me. But who am I, a total novice, though to question my builders' innitial ideas1&2? I need help on how to put any new ideas to him w'out seeming like I'm a sniffy royal pita.

I'll look into the ground screws idea.. have a feeling these are bang-up-to-date solution jobbies.. may just be the ticket, and, may not be in my 64yr old builders' knowledge if so recent a design. But how, should either still shift even a wee bit over time, could I 'jack up' these do-da's?

What I'd have thought best.. in theory.. is surely if these 2 supports could be A) as thin as possible to minimise any hole collapse & rule out as much excavation as possible, & B) deep enough to mitigate against instability. I'm thinking.. again in theory.. of the steel twisty post things/ but bigger/4x as high/ pro done, & somehow tethered to the bank side. Does this idea4 have legs?

Its soft ground.. but if you look at my 2nd pic, the hole would need to be twds very edge of the 'step'/ where the wonky post is on edge of. How coukld a hole be dug here without the side collapsing? I thought of those mini digger probs too.

what is a cantilevered shed?

Ok so in order to dig a hole for a shutter, in my eg/ 4 support points for a 500kg max log cabin/ fancyshed.. does it A) have to be done with a mini digger, B) have to go down to hit 'solid' ground, & C) would a mini digger of 1 ton bugger up going across my new lawn?

Hi Dave- are the 'piles' (I only know the other type..) you refer to, effectively what my builder refers to in idea1? When you say don'y build too close.. you mean to stream, not house I guess? can someone explain what 'shutter' means? Does this idea3 have legs: re-use an old telegragh pole, do the concrete block idea with a 2m section of pole set in the middle. Top of it cut off at precise H > big notch for a solid timber beam to slot into. Any thoughts on this? Ideally this tricky side Id want something I could adjust for height, should there be any 'creep' over time wouldn't I? Appreciated, zoot

Hi chaps- terrific helps thanks (just seen I got these replies!). 'Shed on slope'.. some things are so obvious eh? I'll look into that. Interesting ^.. certainly feasable as 2 for the easy side.. but I'm talking maybe a 3/4m height gap on the RHS: Id need something similar, but 3x as heavy duty/ tall to go deep, as ground here isn't so solid. The stream nearby compromising the ground in the adjacent area. Do you think my quote of £900 (that's not even including anything above the 4 concrete blocks, not even pillar things prior to a base).. is OTT? Appreciated, zootH

Hi all- my 1st thread. My lower garden is narrow 15m with a tricky ~45* slope, down to a stream: a near unuseable area due to profile. My plan to best use it, is to put a 3.5x3.5m log cabin 'across' it, making best use of area & 'covering over' the slope visually. The left side/ easy surely.. but the right side's slope away is the issue, to create support for a base ontop up from here. My builder had 2 ideas (& a hefty quote not inc a base optop- £900). Idea1: exacvate & "shutter 4 300x300mm concrete columns, 2 shallow, 2 deep stream side". Idea2: excavate, nip/ pull one side across, to a barrier (posts/ stacked gravel boards?)/ filling up this side.. to create a level patch. So 4 coners 'pillars' idea? My concern is as ground is not the most stable on slope side, wouldn't a block maybe 'shift' over time pulling the base down & sideways? My concern with Idea2 is the pressure/ weight against the boards, & the new levelled ground 'settling/ sinking a bit over time, with concrete base on > cabin ontop of. Any other ideas? a pic of the lower end, looking to where the front of cabin would be (2nd pic reverse view). Thanks zH

Hi- I'm english Im afraid. Bought my 1st house after 20 yrs of not being able to in england, finally in wales. Quite run down, done a fair bit without prior experience- but stuff to do now trickier so your opinions, & advice if you would gents! thanks zH
