We need to see a photo of the style of the back of your house. It is important that you are consistent so that everything makes sense and is pleasing.

Thank you.! I have taken an image from the living area leading out to the BBQ area then the other two are looking back in from the garden area.

ok great picks - IMO the roof line and style of the house coordinate well with the existing fences which I happen to find modern and pleasing. Do you see how your interior space is mimicked by the fencing when you look from the inside out?

I am hoping you like your existing fencing? If you do AND if it is structurally sound, I would encourage you to stain it! You could keep it the same color (light gray to coordinate with existing patio) OR stain it the same color as the roof OR stain it a brick color (which would read less modern and is my least favorite choice given your interior design style).

show me the Basalt rocks you are referencing? A water feature is always a lovely idea!

Thank you for your comments. Yes, I do now see what you mean about the fence mimicking the inside and I do like it. The fence is not structurally sound and is in need of repair so we do need to replace it. We have thought of staying with timber but maybe changing the size of the timber and close the gap a little.
If we let the hardwood timber grey off, we thought it could resemble the concrete pressed walls. (I'm not sure of the correct terminology).
I have attached pics of the rocks which are to the left of the proposed bbq area. We did think this would be where we would put a water feature. Thanks for your thoughts on that one too!
I have also shown the fireplace structure we are thinking which will go along the right hand side of the patio looking out of the lounge area. This will divide the garden area and patio but still give a view to the garden as we will not have the back wall as shown in this pic. Either side of the wood boxes we will build seating along the same lines as in the other pic.
So now you have the whole idea.
Cheers

your welcome, my pleasure :)

I think I have the whole idea and I agree with your design - your ideas are great!

When you replace your fence it is desirable to let the timber/wood fencing gray naturally as it will coordinate well with your patio color. My only thought is that the chimney you show is rather tall to not have a wall on either side of it for visual balance - meaning make sure you don't build it too high so that it looks like it is sticking up in the middle of nowhere. It has to have landscaping or something around it to anchor it visually.

If you stay with a light gray palate and then accent with either black or charcoal grays plus one or two punch colors for interest; everything will pull together.

Thank you. I appreciate what you are saying and agree with the grey toning. The wall on the back of the bbq will block any view to the garden and I did intend planting around the back of the seats similar to that in the previous image. We could then frame the chimney as well with planting maybe? Something a bit taller. ?
If we stay with the light grey tonings will this clash with the other chimney which is to the left of the proposed fireplace looking at the patio area from the garden. (As shown). The joinery is also this steel grey/blue. ?
Cheers

That steel grey/blue joinery is totally cool! Glad I'm seeing it now - definitely incorporate that color and mimic the lines of it in your fireplace design! You will then connect house to the landscape in a cohesive and pleasing way that makes sense.You may even consider staining your new fence this color also - if you love it. If you are not in love with the color, then just have hints of it in your FP area.

I think I would wait to install my chimney/FP and then decide if plantings around it or anything else would enhance it -

hope these suggestions are helpful to you! :)

Thank you ! !! Cool. Will go with this and probably leave the timber to grey. Will see how chimney looks re planting.
I will post a before and after. It's been great talking to you and your comments appreciated. Cheers.

I'm really happy I could be of assistance - great project - you know what you are doing! Looking forward to seeing your after photos! Enjoy the ride.....;)

If your current grill is still in good shape, perhaps you could built to it rather than replace it.

You also need not bust the budget to have a built backyard BBQ grill.

You have a terrace (one step); perhaps you could consider building your BBQ at a right angle to the fence in the middle of your space so you could walk all the way around it,

perhaps creating a granite countertop around three sides of the actual grill -- built as a cooking island with bar.

If you don't build your grill/chimney against the fence, not only could it be less of a fire hazard to have a wood fence that close to your grill but you would then be able to update your fence, with or without planters or other accessories, as well as your landscaping, at your leisure in any style that pleases and as desired and/or needed in the future and without your grill being in the way -- you could also then use your fence as a back to seating.

Alternately, you could level more of your yard and have a taller retaining wall

and put a green space in the center of it.

By leveling more of your yard and creating a higher retaining wall farther from your home, the wall could also be utilized as seating.

From my experience on my project I suggest... make any bench seating also be storage for cushions in the off season. If you'll use umbrellas in the area just put holes in the patio where they will stand so you can skip the weighted bottom piece. I can post pics of how I did that.

Also, add an in-ground port or two for natural gas for standing patio heaters to be placed around on chilly nights. No propane runs! ALSO... these little tiny projectors that are not much bigger than an iPhone are great to stream and project Netflix HD movies outdoors... bluetooth the sound to some speakers and you have movie or TV night outdoors! Obviously you need a flat, light color wall to project on so take that into account in designing this area. My patio movies are 100" diagonal and super bright. Good luck!
