Sounds like you have a good plan, call an experienced, recommended, reliable contractor. Maybe he/she can help you with an interior room divider, for the front door direct to lounge problem too. Here are some ideas https://www.houzz.com/products/room-divider-prbr0lbl-pl~l_38829

Hi definitely remove the x bars on the deck balustrade. Landscape close to the house so it grounds the house. Trees will make it look less bare. Chose some that work for your area, that are evergreen, and are not going to grow really big. With a really plain house - dark colors will make it look better. Dark Grey, or black with a warm tone so it doesn't have a blue undertone in it. Make sure it is a warm grey or black. Use green foliage around it. Paint out the pergola in the dark grey too or white if you want a different look. Fill in the balustrade where the x is removed with plants in front of those areas. Grow a vine up the pergola that is nice.

There is no common link, no continuity that each dwelling share. i would introduce an element to both structures, borrowed fm the other, so for example the red brick and windows are the most striking design elements in the house, however the rendered garage with a parapet and no visible roof may as well be from another planet, I would brick up the front piers aside the door, with matching red brick, and then I'd install some post and beam rafters that could extend over beyond the garage door, almost like a flat eave, however just beams, no roof, and paint it chacoal, I'd then link a path from th garage to the house, and create the same detail at the porch entry of the home, same beams, colour and materials, so it looks like they belong on the same property. also, perhaps a little scary to consider, i would render the wall in between the door and the first window only, and paint the front door in the matching blue. Windows I'd go charcoal as per th beam structure, and apply a stained timber batten to the flat parapet above the garage, so paint that black, then fix timber battens vertically wh enough spacing to see that black shadowline, it will modernise it, emphasising the elongated design, which is both contemporary and popular, and tie this timber detail into the house with a generous deck. Both timbers will link, over scale th deck, perhaps stagger a step or two, as the garage is over scaled also. remove the fence, and landscape the corner with over scaled shrubbery, a meandering path to help invite ppl between the two structures., the visual disconnection is the fence, but it translates into everything else. if a fence must be, then consider a half height one, or an informal row of sleepers as uprights, to softly define the yard.

I haqve just seen this , and it is well over a year old , so presumably you are well into renovations , or maybe finished . Here's my take though -- probably too late though ! Your picture looks like those 70's photo's that faded and yellowed ( sorry to be rude ) . So freshen and modernise . Paint the walls white -- not beige or yellow . It will look so much 'cleaner' . redo the dark uprights and base boards -- I can't tell if they are dark green , or black , but I'd do black stain over it . The fence I would also do in black . The yard , step one , would be hide and soften it . The Cape Cod chair paint in white , with the pailings in bright primary colours -- each one different . Add 2 or 3 planters -- different shapes and sizes and heights , but all stained a nice Kwila brown or charcoal or similar . Big leafy plants , cactuses , yukkas , maybe white and light brown pebbles , marigolds , colour , texture , different height plants . Personally , I would go further -- paint the roof , rip up most of the pavers , possibly even change the windows to bronze or charcoal frames . Just some quick ideas from an experienced amateur haha .
