Ok - here are some ideas - Move the shed up against the house wall and pizza oven - make it so that it is an odd shape and follows the house roof. Put the HWS in the shed in the traingle corner.
Add a lean too cover behind the pizza oven connected to the shed for storage of bikes.
This gives a bigger/better shed.
Now you have a min 1.8m square to play in to set up...a bbq, sink and external bar with font etc.
This is also a step closer to the proposed outdoor living area.
I would make this at least level with pizza oven if not come forward more towards the Ent Area.
You will need three walls back clothesline side and pizza oven side.and a gabled roof like a gazeebo.
get some cool room panels and try for 1.2m wide by 1.2m cnr cool room.
I have had ago with Paint - hope you get the idea....and this helps
Cheers GMK they are some great ideas.
I wrote this (below) before I read your post, but now you have me thinking again.
--------------------------
I am no longer going with a "beer wall" but all this has got me thinking about how I can organise the space in my back yard to serve beer and to manage storage.
With a block the size of mine (215m2) storage space is a premium and this is a key driver in what I finally implement. Key to storage space is a place to store my Ag gear, fermenting fridge, garden tools and bikes. As I am currently doing some renovations which will be finished well with the rear of the house predominately glass, how it all comes together and looks is also very important and finally but not least important is how the beer serves. No point building something that looks great, maximises space but pours a hot beer.
Sorry I should add one more consideration and a very important one - Cost. Compared to the cost of the reno's it is not big numbers, but I am not into throwing money away.
Anyway my thoughts so far is to maintain the design of the back yard similar to how the current design is in the OP. From this design I would remove the BBQ and replace it with a keg setup (converted freezer or pre-built kegerator). I would look at pushing the sink and the keg further back towards the fence (however maintaining the shape). Behind the sink/keg system would be a planter box and fence height wall and behind that I would like to use the space used for storage and for my hot water system. I should have enough room to access it behind the pizza oven. In this storage space I could possible store my bikes/ag gear/fermenting fridge/ gardening tools (but obviously not all), I would need to make it partially covered. I would really like to significantly reduce the size of the shed to give the back yard more space (the house reno's are consuming some back yard). Preferably I would like a low shed at a similar height to the pizza oven.
So in terms of how I manage my brewing and serving I have been thinking about the following questions.
Can you fit a Coopers fermenter in a bar fridge (if not what type of fermenter - I have read Bunnings 23L, but is that all?). The bar fridge could easily fit in the storage area or possibly next to the sink and keg setup (i think there will be roughly 1.6m of bench space at the front).
I think I could carry a full fermenter behind the pizza oven, if not I could use a trolley.
If the fridge goes in the storage area it leaves me with space under the bench top at the front. In fact there is space under the planter box that I could utilise.
I have looked at the pre-built kegerator systems eg
ebay
And that would quite comfortably fit in replace of the BBQ. The price for $500 also looks very good (included 2 tap tower font, and reg). What I don't know about these is how they compare to a custom built kegerator from a chest freezer. Particularly in terms of dimensions, efficiency, cost and features. What is the quality of these systems? I had a look at the freezer conversion that CM2 did and it cost a bit more, but obviously has more features (better quality parts???). Over all though if I scaled back CM2's to the size of the Kegerator I think it still comes up more expensive (CM2 that looks great by the way).
If I have a tower font I think I would go with a fan and tube or water pump to cool it. If I go with taps through a collar cooling is obviously is not required.
I noticed in CM2's conversion see
here
he has non-return valves, excuse my ignorance but why are they required and can you fit them to an off the shelf kegerator?
Anyway they are my thoughts for now. I need to mark out the backyard to see if things will actually fit in a practical sense, but the weather is filthy in Perth at the minute so maybe on the weekend.
Thanks everyone on their thoughts so far, it has given me a lot to think about.
Oh and yes I want to stick to utilising just this corner of the yard.
