Congratulations Mark! I really like the drawings that you did up with the new door and deck at the front. It makes a huge difference to the house. I think the all grass look at the front is a bit much. It would benefit from some sort of pathway to the deck, but I don't have the imagination of the other Houzzers, but I love what you have done so far.

what a great house!! make sure all the paint and trim is in excellent condition, what about Colorbond Cove and/or Evening Haze for over the windows and roller door with bright white trim and a startling front door (turquoise?) is the flue being used? remove or clean and paint, move the tv aerial out of sight, remove or replace the awnings with better fitting blinds that fit inside the window frames (Sarlon roller blinds will be more discreet and reasonably priced) remove the old planting near the house and add a mowing strip along the walls, clean the concrete driveway and create a gravelled parking area instead of parking on the grass with just a triangle of generous plants between the drive and parking area, level the lawn closer to the house with a low curved retaining wall made of of railway sleepers and prune back the big shrubs to see the edges of the house, improve the lawn and add planting along the retaining wall or right down to the front fence...Dietes, Grasses, and other architectural plants will look good

As others have said, it's all about balance. Firstly, replace the seemingly pointless area of paving to the left of the door with turf while keeping the sandstone garden edging. If you need the parking bay in front of the house reduce it down to in line with the corner of the house and make the garden in front of the house deeper by removing more pavers. If you don't need the parking bay get rid of it all together and turf that area. To make the front door easier to find remove everything in that garden to the right of the Frangipani (which needs some selective pruning) and then run a path from the footpath (or steppers) to the porch. I would also place a feature plant in a pot to the left of the front door to draw the eye and paint the door a lighter colour so it stands out. Lastly, a feature tree in the garden to the left near the Wooly Bush to add some height to that side of the garden.

Absolutely agree about hedge... Leave it but have it trimmed and add trees to courtyard. I would decide on colour scheme first by painting large pieces of cardboard in a colour suite to complement the brick. Draw out lighter colours in brick & tone down with white to match look.... I would not personally use white paint as your brick is so dark.... Think cohesion not contrast... Ideas above re gate, letterbox, etc are excellent and another way to add interest... Also think about changing driveway colour to match house/garden as it is a big slab of grey... Your roof is dominant too...... Maybe get that done rather than rendering house walls.... I would look on houzz for ideas.... Look up Prairie style or Frank Lloyd Wright or Fallingwater his most famous house for colour/style ideas.... Or Taliesin West for anchoring house into land innovatively. Paint that chimney flue to hide it!!!!!!
