VERY CLEVER and looks SO inviting!! The way you've created such a usable and friendly area and atmosphere. Congrats.

Marrying old and new is hard to pull off successfully. Good for you.

Yes, the back half past the original 2 rooms where usually are lean-to structures were demolished and a new 2 storey structure added. The condition of the back part was poor, the bricks could be pulled out by bare hands as discovered during demolition!

I'm obviously weird . Three things that I find strange -- -- Wouldn't you do the tank before building the garage and Air B N B ? Makes everything easier , and if you are worried that the tank won't stand up to utes and trucks driving over it , then its probably going to give problems at some stage anyway ? -- Why do the garage door in timber ; the gate in what looks like 'plasticated timber' or maybe its painted , not stained , and then the roof thing in a different style and colour and roof pitch ? The fence down the right hand boundary looks unstained -- are they going to leave it like that , or maybe add a 4th brown , or maybe charcoal ? The roof thing looks like pavers , in another colour again ( plus personally I dont like pavers -- they move and wobble in time ) . Me , as a complete amateur , I love the concept and most of the execution , with the exception of that roof thing ( do you call it a pergoda ? ) . Floor would be in the same aggregate concrete as the drive if I was doing it . A built in BBQ and/or fire pit in a wall ( or 2 shorter walls making a corner ) , done in the limestone and render , with the grey gutters . The roof only over half the area -- the rest in a pergola ( open ) style , made of the same timber and same stain as the garage door ( and obviously the automatic gate would have been specified exactly the same ) . The smaller part of the roof in a steeper pitch , with a fake shutter to match the garage . The pergola in a flatter style . Me -- I'd add a spa or similar too . Basically -- have one person design and execute it , not a 'team' .
