Just love that rabbit perhaps his hutch would be good to the left on the top terrace The sandstone rock and stairs to the left of your house could be worked on to look really special again, a Zen like The fern that was moved off the rocks is likened to a weed and best removed, I quite like the rock as a feature. As for any pavers any of the square or rectangle concrete ones would look great and are cheaper than most, please don't paint them you can get them from Bunnings. We also play Bocci on our grass that over looks water. great fun.

Who ever is quoting on your windows, get them to run quotes on glass of various thicknesses. We ended up with 11mm glass in our stackers because the price difference between the thinner glass was negligible....we were really surprised.

Hi Dr Retro, Thank you. I really appreciate the input and the time you've taken to explanation your point of view. I really do want to get an understanding of where the issues lie in this design. So I hope you'll forgive me digging a little deeper. I don't quite follow why you think the design would require a 6m lintel. Yes, it does require a 6m track, but the track can simply be attached to the wall. The weight of the door need not be supported by the top track. It could be supported from below. The whole point of putting the configuration on the outside of the wall is to minimize the need to make structural changes to the building. There currently is no capacity to install a 6m wide external sliding door/window unit. Likewise I don't follow why the door should be any draftier than any other external sliding doors. The cavity is on the outside of the wall, so draft is not going to get in via the cavity. Other sliding doors of the unit type have the same draft problems this configuration would and solve it by using an overlapping flange at the front end of the fixed door and the back end of the slider. The same could be applied here, where we treat the wall as the fixed door.The point at which the doors engage each other has also be solved for other door configurations. It is just a matter of having a loose tongue and groove configuration. Again this is exactly the same as a unit providing center opening sliding doors. Finally the same sliding mechanisms are used in other sliding door configurations, so I don't see why that should be any draftier here either.

If it is bare particleboard then my short answer is probably no, it is not worth paying double for better quality doors. Like I said, I haven't seen unfinished particle board inside cupboards in a long time. If it is laminated particleboard then it might be worth it. Like The Joinery Store said, laminated interiors are typical. Plywood is not unheard of (and I think it is more common in some other countries) but it would be unusual if you did not specifically request it. Just to be clear, the cupboard has been built and has laminate doors, and you are getting quotes to change the doors? For what reason are you thinking of changing them? What do you want the doors to look like from the outside? Do you want them to match any other doors or features in the room which are timber or poly?
