How about the front in grass clumps and shrubs? Then a couple of taller trees in the "back" near the windows...

Unfortunately it is also a requirement in the CCC District plan restricting ones fence height being over 1.8m. There are also stipulations about visibility of no more than 50% through the fencing so most home owners opt for the cheap solid timber fence. It is rather frustrating when we design these beautiful homes and the client has no regard for landscaping and the house is subsequently 'blocked from view.' Perhaps a little more client education would go along way for us to push some great landscaping designs and make more of a house on a section.

Wow - what a view! Yes definitely take the curtains to the ceiling it will add grandeur and frame the view even more beautifully. You can get a custom bent track made that will take the curtains around the corner so the window is not obscured when the curtain are open.

The colonial style in your bottom picture looks nice , but I don't think it would suit your house style . I gather you are older , but the existing colours are from different eras IMO . The burgundy/red colour I like , and although the downstairs windows look quite old , I would paint them the same colour , and the seat too . Upstairs I'd definitely change the window -- the louvres are so dated ! Go a bit bigger if you can , but that may get into structural problems . Have top-hinged opening windows eaither side , and a larger piece of fixed glass in the middle . Either no surround , or a surround to match the downstairs windows and door frame , painted to match . All the roof and side ribbed steel panels I would repaint in a gunmetal grey , and get away from that dark green . The roof on the room to the left I would also do , to 'tie it' in . I'd leave that small roof above the door , and add a roofed gazebbo out the front , with stained or varnished solid wood uprights , and a roof painted in that burgundy red . I would build it to fit onto the lower deck level -- way easier and cheaper to do it that way , as opposed to raising and enlarging the deck . Add a couple of natural timber planters , even a half barrel or two , a shint stainless barbeque , and some charcoal coated aluminium outdoor chairs and a matching glass top table . Personally , I can't imagine a roof / portico attached to the existing house that would suit the style and not make the downstairs ( inside ) too dark . A stand alone roofed timber gazebo would offer the best of both , at a reasonable price . One last idea -- the latticework on the 'fence' -- repaint it an English Off-White , while keeping the rails and posts that burgundy red -- it would add interest and lift it IMO . If you are younger , then go crazy -- bright orange window surrounds , blue/grey render and charcoal roof -- a big round upstairs window , and 6 outdoor chairs , each in a different bright colour !
