What do they want to achieve , and what is their budget ?

just to get ideas rolling , if it was my place , I would offer the following --

-- the garage looks a a different style and different shade of grey . I'd repaint in the same grey .

-- I'd paint the front door in a brilliant red , and the narrow garage door surrounds in the same colour -- tie it in a bit better .

-- 'Hide' the four flaxes the same shape and colour ? I'd add 3 or 4 tall or bright easycare plants -- a cactus , a yukka , a native , get some variety , maybe even remove a flax or two .

-- I'd add a couple of big 'egyptian' pots , at least 800mm wide and at least a metre tall , one each side of the driveway ( on the grass ) , placed so they look random . Fill with a mix of plants of your choice -- at least some in red shades to tie in with the front door .

-- I'd price a light covering of tar / asphalt over the driveway , to tidy it more .

A good start on a budget , hopefully under $10K ?
