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.

ensimpson, Please do not render that brick. It is quite a nice brick and render can look very cheap and often done poorly cracks and looks even worse. If you don't like the dutch cables, you can go about removing them. These are not primary roof structure typically, but there will be a little work in making good the roof where they were. Alternatively, give these gables a function, place a fixed louvre, like you have shown in the attached image and allow the roof to vent through them. This will also impact the comfort of the home as there will be less heat buildup in the roof cavity. I agree with the comment above, the driveway is very prominent. This is partly the perspective of this image, but you could consider options for the driveway paving. I do not think painting grey is a good one. Repaving with a natural grey material could be as there would be more life and texture to it, but it is an expensive one.

Please post photos, and dimensions.

This is a great article.... thank you for sharing :). Be nice to see this in the 'stories' section where everyone will see it.
