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 . .

Well, for lack of a better idea, since you find it a drafty little space. I'm assuming the draft comes in on the right? Most of the necessities in the area are located of the left side; i.e. vent, thermostat, light switch etc. What I would do I think is caulk up the drafty spots, maybe even add sized poster board wrapped in batting I covered in a gorgeous fuscia with diagonal grosgrain ribbons every which way covered with a heavy velvet to be attached to the area above & below the window. (Of course remove the drapes that are hanging in there). This for the purpose of using it as a pin-it board for notes. Attach a table height board covered in felt to carry across the full width of the little room. Leaving just enough space for a comfortable little antique desk chair. Paint the back wall a bright cobalt blue, paint the ceiling a silvery pearlescent white. Find a way to attach a clip-on task lamp. And stretch a heavy duty enough wire across the top of the opening and complete it with a heavy doubled velvet drape with a drooping valance. Place a swag with fringe & jewels on it to be closed when not in use. Voila intrigue is yours!

With any post war house built in the 50's the connection from in to out is non existent. Depending on where living rooms are located i would take some of the fantastic windows out and replace them with French doors, or bi folding doors and connect the house to the site. The colour scheme from Karen is perfect to lift the kerb appeal and give it a modern twist. With land costing more than houses these days and the fact that you seem to have quite a big block, after looking at paint colours, opening up the living dining kitchen areas to the outside with a roofed area. Even combining a flat roofed carport which will widen the house to the street making it seem a bigger house, can carry the new look with say an enclosed section for garden equipment, to the opposite side to the house, and if you are lucky enough to have that near the living area it can be used as both car cover and outdoor living. I always think a good landscape architect is worth their weight in gold, to give you a landscape plan, to suit the soil type, your skills level and your preference in planting. Divide up the exterior space to provide outdoor rooms under a tree, paths that lead to some special spot for kids, maybe even a veggie patch with a chock run, and make sure that you use the entire yard, front and back by enclosing part of the front yard in fencing which suits the style of the house, while providing some planting to the street. If allowed a gate structure to blend in with the house, a dedicated pathway with planting each side to the front door, fantastic fencing and consider natural materials like a hand laid stone fence with timber or powder-coated aluminium inserts, to give this house an entry, not sure where the front door is now, so that is not a good look. Gardens always enhance a house, they are never a wasted effort, and if you are not gardeners, make sure the landscape architect knows that and he will be able to select low maintenance plants. All the paint in the world will not give the desired effort that the garden will do to that paint work.
