Try this. Hang the television to the right of the wood stove on the wall opposite the french doors. Use the wall with the high windows for a looong sofa and add two chairs across / angled slightly - low back so you can look over one to television. use console / sofa table on entry /bed door wall just past where entry door opens so you have a lay down surface. Forget glass, it isn't for this era and won't make it feel bigger. Paint ALL french doors inside and out and small windows and entry door same color and trim same color too. Try a charcoal rather than a black - something in the blue-green-gray shades like new providence navy. do all the walls in kitchen and living in a warm white - this tone has the wood as an undertone - http://www.benjaminmoore.com/en-us/paint-color/woodash then, for the cabinets . . do a bungalow thing and go deeper on the cabinets to a classic drabware tone - with the wood walls and floors / try bm bracken biscuit http://www.benjaminmoore.com/en-us/paint-color/brackenbiscuit these will all go together like gangbusters, keep it light and bright but interesting and work with a new blue green gray back door in a tone like bm beach glass http://www.benjaminmoore.com/en-us/paint-color/beachglass templeton gray as a counterpoint on some craigslist piece of furniture . . add warm undertone tan and oatmeal nubby tweed upholstery to start . . the teal navy gray will work with the black iron stove and accents without going black. start keeping the left door to the kitchen closed and get a door stop to hold the other one open permanently . . this will work because you need a little more wall to make the tv work well - in the kitchen, pull your table away from the wall just a tad - consider a padded bench on the wall to provide a kind of sitting space in there and put the chairs across - if you shift your television to the wall (high enough the heat is not an issue , you can still have big speakers work well - and remote the media equipment - run the wire and patch the holes. Hang it mid-height - eye level when you sit plus 15 degrees . . check out the amazing sconces you can put on the entry wall - shades of light petersik pendant with home-made trim wood brace to pump it out from the wall since the power is high? over the console? round wood table in middle - even a hd butcherblock round on a painted drum base in trim tone? With those tones - teal gray, biscuit, creamy off-white, muted blue-greens - paint your white chairs and a hand me down bench wythe blue and find a graphic sunbrella print with a little blue green, chocolate and orange for cushions and pad skirts with velcro at the table . . make a galvinized pipe leg / plank 1 x 12 / clear finish console for behind the door . . now you are cooking with gas . .

There are different kinds of ivy and plant privacy screens that can be purchased which might cover your fence and gate and give you the privacy you are looking for. I have not used them before but the photos look very nice. If you picked a color to match your side or front bushes, it would look very nice and becost effective as well. You have a beautiful home. Good luck and please post photos of the final.

Thanks very much for all your feedback. Just to answer a few queries - the deck is directly outside the main room so the new doors open out onto it. The doors won't be French - they're just the only doors that the 3D planner I'm using had, they'll actually be large stacking doors. I've had another idea too which would be a lot more expensive but offers a completely different approach. This is quite rushed so doesn't show accurate layout of kitchen or anything like that, basically just provides an idea. Thoughts!?

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 !
