New shed of complicated structure

[old_picker]

Mate, my old tin shed was sitting on the ground, and I tell ya it wasn't pretty - rot, mud, moisture on the floor at all times. That's why i wanna lift it up a bit. I thought concrete slab is the only way. But I hear ya - you are saying to build it on stumps?
1. If it is a 2.5x2.5 meters - one at each corner - would that be enough? 2. If I use my house's wall as one of the sheds walls - should I use stumps on that side too or do I nail the floor to the brickwork?
3. When I move my HWS - at the back of it there is just a cement sheet, ie no bricks. Do I leave it like that since it'll be inside the shed or do I need to properly cover the hole?

4. And the last but not the least important question - how hard/expensive would it be to move the HWS???



I am half a meter below my neghbour's block (that's what the new retaining wall was for), so, really all his water will flow to and under my shed. BUt I am going to install gatas and direct the water somewhere.

1.Stumps are 600 apart with joist on top then bearers on top of that running in the oposit direction - the flooring goes on top of that

Seems like overkill to me for such a small shed. I have done it with the floor made of palletts to get off the gound.

If the retaining wall is built properly you shouldnt get runnoff from your neighbors place. It should have a slotted drain at the base on the high side set in 3-400mm of coarse screeings. This slotted drain should be connected to the nearest stormie. All you should have to consider is water from the shed roof. Have the fall towards the front with spouting running to the garden or stormie if close.

You can use black plastic sheet under the palletts as a moisture barrier. Put sand down first. The floor is not a part of the structure at all.

The main structure is simple post and rail with infill of whatever. I would use 4x4 posts i each corner and one between.

3&4 These issues will be taken care of by the plumber you hire to shift the HWS.

Hard? No the plumber does it all to the very strict regulations in force with gas and hot water.
Expensive? It will cost a lot of money as the house hot water plumbing is designed to run from that point. Your kitchen/bathroom is probably close to that corner. The expense will be rerouting the main hotwater feed to the new location of the hws. Also if it is much further away yiou will notice that you have to run taps longer before you get hot water thereby using more water.

The HWS is the big issue with this project as you are not able to have it inside the shed. It may be cheaper to replace it with an instant return system which can be inside the shed and will mount directly to the wall. You will need to flue to the outside.

Thanks for all the info. Looks like it is not a weekend project after all.
With the HWS - I was thinking of moving it a meter (around that) towards the window. So it'll right in front of the new shed and access to it won't be a prob.
Another option is to move it to the left corner (house wall and fence) and build a gate from the front yard in the new fence. The shed in this instance will be of an L shape. More complicated option.

So, moving it a meter or so - it won't have great effect on the water supply, will it? From my understanding plumbing shouldn't cost too much, should it?

try going to a 'real' shed company. None of this Aarons "cubbyhouse" type stuff. Try FairDinkim sheds or Safety Steel or any of the others listed in either the trading post or the weekly times. They will all custom build to your requirements.

Fair Dinkim, Safety Steel do not make small sheds - just called all of them and the answer was - go to bunnings...
