yes...but windows need to suit the room inside, orientation and outlook and looking at your photo you may find that it's more cost effective to remove three small windows and replace with one big window that may be all sliding or have sections of fixed glass and sections of awnings or double hung windows either horizontally or vertically...but do you need every window in the original size and location? ..take photos from every side of your house and make a numbered list of the sizes of all the existing windows and you can discuss with a window supplier to get an idea of costs BUT windows are such a vital feature of passive solar design that you should take this opportunity to rethink every window....does every window suit the purpose, are some windows too big, too hot inside, in the wrong location, not private, missing a good view or cooling breeze...check yourhome.gov.au for advice to get the best results for such a major investment and you will need skilled help to remove and install so also time to consult a builder

Wow there are so many angles on the rooves (roofs?)... I don't know the right or best option but I imagine the deck being curved, to create some interest. I want bug chunky timbers in dark stain like recycled wharf beams or railway sleepers. I think start by removing the little roof over the porch and opening it up flush with the brick wall of the front door. Then install chunky beams (wood or steel) that fly quite high and straight over the void between the 2 sides of the house. I would use a polycarbonate roof in that area to let extra light through and not make the house entrance too dark. The area behind the carport where the deck is level with the rear of house, I would have a solid roof that matching the pitch of the back of the house, or even not have a roof at all. I would leave the entry deck area and the curve unprotected. My only question is this... is this an area you would hang out seeing its quite disconnected from the living areas? perhaps having a more ramp like entrance with interesting trees in the void area and making a matching deck on the other side might work. I just feel if its only going to be an entrance its a big capital investment and an expensive exercise with all the roofing.

i believe that awnings are usually more expensive and then you will have to choose a colour for handles that can add to the cost but you don't have to have the same style for every window ... it's such an important feature that you need to consider each window separately to make sure that the open awning doesn't encroach on outside paths etc or the sliding window won't be accidentally left open when it rains and some windows can be too narrow for sliding windows and awnings look better.. we have a combination of awning, sliding and stacking windows and doors and our awning highlight windows have electric openers to save having to climb on a ladder to reach the handle

I guess the first question is what do you want to achieve ?Do you want a more modern look , or a more useful space ? In other words , looks or practicality ? Looks wise , I thgink you need a plan for the whole house . I'm not a fan of brown , but the darker brown around the window looks good -- the gutters , the dirty white of that canopy , the wrought iron less so . Just me , I'd waterblast everything , I'd cut off the wrought iron ( an angle grinder should do fine ) , and paint the gutters , and the concrete canopy , in that darker khaki brown , or a metallic charcoal 9 that would need the window and surround done too ) . As far as a deck , basically I'd go a square , the size of the 'moon' one there , if that makes sense , so probably 2.5 x 2.5 or whatever the distance from the front door to the very front wall is . Stain it that khaki brown , or charcoal ( the same as gutters etc , not some brown , some charcoal ) . And the canopy I'd 'square' that too in an open beam -- leave the existing concrete canopy , just add and square it off , same size as the deck . Any bigger it will look out of proportion , I personally wouldn't have railings or built in seating ( who wants to sit out the front for longer periods IMO ) , just step down to lawn or footpath .
