Hi Marc, have a look at this new story from architect Dom Bagnato for inspiration: https://www.houzz.com.au/magazine/how-to-build-recycled-and-discarded-material-into-your-home-stsetivw-vs~31393879

John you are fortunate to have such a yard, although the tennis court does aspect as a divider breaking up the space, I think this creates an opportunity to create garden zones or rooms. Intimate garden spaces can be individual enough and still be integrated into a larger footprint. Your garden perhaps may be viewed from different windows, and have different aspects, therefore will have different requiremnts of sun, shelter etc. As the second picture appears to have a shed or structure, and looks more of a utility space, I would obstruct the view from the court, by planting a Boston ivy to cover the fencing, providing a delicate hanging foliage wi ever changing colours of reds and greens. I would do the same on the opposite fencing that overlooks the main lawn area, although I would create a large window effect by clipping or restraining the creeper from a large square in the centre fencing section. Tis will create a room with a view in the foreground, and with effective and clever planting, lighting and design elements, you will create an interesting viewpoint that will direct interest into the yard beyond the court. In the background, the timber fence I would plant your murray a hedge, so the small blooms will soften the look of the fence, paint it a dark colour, like domino by dulux so the foliage stands out against it, and gives an illusion of a deeper boundary. In front of that, centre to your created window in your fencing, place either a sculptural element, in the form of an urn, a formal topiary or statue, perhaps a small water feature with lighting, so it extends the perspective yet again. With the green hedges now creating the walls of your garden room, plant your chosen iceberg roses in front of that, and some informal plantings below. I suggest a bench to watch a match or two, and utilize the other garden Rea to house things such as your patio furniture. Garden rooms don't necessarily make a space smaller, rather they may invite you to meander through garden rooms with beautiful elements and relaxing places to sit. I would also like the look of manchurian pear trees along the fencing if you don't like the idea of a creeper.

Katherine, I am just curious about the look of the rest of your house? For example, what look is the kitchen and external look of house. I love your bathroom, but not sure if it would match the era of my house. I am beginning to think that in bathrooms, they really only look unique and have an extra "something" when the floors aren't the typical grey, charcoal, beige........not sure what to do yet with mine...

I love Siruskeys idea ! I must admit , if it was me , I would have been more inclined to get some post extensions ( wood the same 100 x 100 or whatever it is ) , unbolt the top , get some galv brackets made with a 'hook' on half of them , bolt the old and new together using the brackets , then do everything in charcoal . Of course , these new brackets ( flat steel say 30-40mm wide and 6-8mm thick ) will look a bit funny , and the charcoal stain won't take the same , so they'll always look a bit out of place . But thats why you get the engineers to put a 'hook' on them before you send to the galvanisers -- a bit of 8mm solid rod coming 120mm or so out , with a couple of small bends , one down , one up . Yes , hang hanging plants on them -- takes the focus away from the poles , the extensions , adds some colour and 'life' . But I'm a lot more rip than sirus haha ! Oh , and I'd paint or tile the deck , probably charcoal to match the windows , or terracota to suit the style , but even off-white or grey ( if tiling ) would work . The brown less so .
