It looks like the one Charlie Albone did was a plastic screen (Bunnings) adhered to a mirror. Im not certain what type of mirror he used. You might be able to find large acrylic mirrors through plastic suppliers. These would be suitable outdoors.

Hi fb57, Great charming federation house, retain the front and fix the back, then maybe later you can put in a granny flat - depending on cost and local council bylaws. I would not put in an attic - stairs are a good place for mishaps and as we age it might have limited functionality - but if its something you have your heart set on it might prove worth while. It appears that you are competent enough to do a decent measure up plan, going from what you have posted - you might need to take a few photo and a few other dimension to get a good design from someone working online. The idea is to get a design that you are happy with and then get a local competent Drafts-person to do your working drawings for a Building Permit and then get it built with a Builder of your choice. This would result in my opinion in a significant saving and a design of your choice, especially if you are willing to do some of the legwork with council and other authorities. To get a good design that you feel is a solution to your requirements, you need to produce a variety of design schemes (plans elevations perspectives etc.) and this can be done online with any competent Building Designer that you can get along with. It will not take one go at it - and it will not be quick, as you need time to digest every scheme but generally it works out in the long run. These are some of the things I would look at: 1. The possibility of breaking up the build into stages - maybe stage one do the renovations at the back and the stage 2 place in a granny flat. 2. As you have good access on both sides of the property I would place a new garage on the largest width and possible gate and walkway on the other side to give individual access to the granny flat. The new garage would be as closely to the front as possible, with the new fence an gate on the other side it would greatly improve security. 3. Depending on budget I would provide a bathroom shower and toilet with a walk in robe to the main bedroom and redo the kitchen and laundry if required. 4.The area next to the lounge area I would develop into an external entertainment area. 5 Since you mentioned that you have a "Fibro Extension" it implies to me that you may have asbestos on the property - get an expert in and determine if you need to remove asbestos when you renovate - this is a dangerous material and you should take all precautions possible to avoid long term damage. 6. An indication of the position of your neighbors windows and setback might also help in providing a design that complies with your planning laws and respects your adjoining neighbors. Like all things it will take a few revisions to get it right , but if you are willing to work at it, it will payoff in the end. The first thing is to draw up the existing conditions to scale so that an initial proposal showing possibilities can be worked on. I would be willing to work on this project with you online, I hope this is of some help. Regards Michael Manias mm407p@gmail.com

Awesome. Thanks guys. Yep - in QLD and is a very breezy home so I’m not too worried about air flow. If I get smaller furniture it would be so I could easily clean underneath and retrieve lost LEGO;) I fear that I’ve already got TV too high but if I move it I will definitely go lower - have a sore neck. And although is living room it is mostly used for TV. Kids have toy room for playing and many of our conversations happen on our dining table or outside areas. So comfort is a large consideration. Thanks everyone for your suggestions so far!

always good to please your husband and you'll have a better chance of achieving a good result together....cost will depend too much on the reality of the site to guestimate...we always begin by consulting a builder to check the existing building to see what's possible structurally, check with Council to see what's legal and then you'll need formal plans drawn up so you can collect quotes but i'd be inclined to ask about the whole project as you may have a better chance of attracting an experienced custom builder for a bigger job than just the small extension (even if you negotiate to have the work done in stages ...best of luck
