I would plant along the fence line trees like Magnolia (Little Gem) or Hibiscus, and there where the wider part - low shrubs under the trees or stripy Dianella. All these plants and trees are hardy and easy to take care of. Trees don't drop the leaves and slow growing. Otherwise you can place pots with bright plants (Frangipani grows well in the pots). You can mulch the soil under the trees or put some pebbles or gravel like I did (see the photos).

Great job, looks so much better. :)

You can install real timber either direct stick to concrete or 'planks on ply'. Perhaps get a reputable timber flooring company to come out and advise. You don't necessarily have to get engineered or laminate

Great house design! I️ like the arches in the drawing rather than the 3D render however I️ don’t think that’s the only thing going on. The staircase leading up to it looks really heavy and narrow. I️ feel like the house is getting squeezed and it’s holding its breath! The rest of the design is clearly anchored into the site but the combo of tight rigid staircase, high arches and the vertical exposed bricks mean the front is out of proportion. Maybe make sure the arches are “wider” as per the drawing and perhaps the staircase walls are timber like the rest and I️ think the squeeze effect I️ see will be relaxed. I️ really hope this makes sense because when I️ read it back it sounds mad!
