having been researching 2nd storey additions and everywhere i look i see the 2nd storey added as a popup, for want of a better explanation, where it is a timber frame inside the existing roofline. Just wondering what the reason is behind this approach? Is it cheaper and easier? if so why? or it it aesthetics? I could understand if you were going to class in a different material it might look odd, but if going to render the whole house it should be ok to extend up over the existing outer wall footprint?

It depends on a few things , mostly money. A 50 sqm 2nd storey extension is obviously going to be a lot cheaper than one covering the entire ground floor - 120 sq m ( as a rough guide ). Secondly some councils are pretty strict with their side boundary setbacks for upper floors so they have to be set back from the ground floor considerably.
Sometimes people only want a big master bedroom, parents retreat and big ensuite and WIR up there. No kids rooms!
In my opinion a lot of pop tops look like crap. We have two opposite us and a few locally and they all look pretty ordinary.

They are also called SIPs, eskyaddons, Light frame modular, etc and they aren't new, but they are proving popular,they are also quicker to install, lightweight and don't require expensive external scaffold, in some cases a few sheets of ply over the floor/ceiling joists are used as platforms compared to $20K external steel scaffolding rental & plant hire. Things also to consider, environmental factors,durability, resale value,etc

I think he is talking about the ones we have over here on the east coast - timber framing clad with weatherboards or sheet cladding then acrylic render.

I have no doubts you will see this system popping up over East

Maybe but a couple I've seen looked every bit as cheap and nasty as some of the others. I still think if you keep any addition or extension with the same materials as the rest of the house on the outside will look better than going for something just because it is cheaper. Keep the same roof pitch, the same roof cladding, the same cladding on the outside of the walls, the same type of windows etc. If it is brick and the cost to make upstairs brick as well is too much then render the rest of the house and paint it all the same colour.
I'm sure there would be a big cost benefit when you eventually sell to this argument as well.

thanks guys very useful feedback. have added Sydney into my profile location. interesting to note the potential saving in scaffolding costs.
aside from the costing on the floor area and therefore materials, would realigning the pitches if yge different rooflines to match be expensive, or would they generally only have to match the pitch on the new roof to the old roof which has now been cut out. Aesthetically i am not sold on these popups but i guess it is a cheaper way to add floor space especially if all the trusses and framing is prefabricated offsite.

I'd have to see a floorplan, some elevations and/or some photos before commenting.
I don't understand what you are trying to do but aligning a new roof to an old is not that hard to do.
Most guys doing second storey additions use pre-cut frames and trusses anyway .

no, just general questions to improve my knowledge. At some point i will be looking to buy, so just trying to understand some of the options and costs ahead of time. it then allows me to make a better informed decision on what type of property to look for.

Good for you..knowledge is very powerful

Understanding Risk is also important.
it then allows me to make a better informed decision on what type of property to look for.
The old rule of thumb was to look for a property 40% below replacement cost
The problem is the average punter decides on emotion and then asks questions.
These days with software/apps you can factor and analyse any variable combination with precision beforehand
Google will tell you algorithms run the world..these-days..

If you are looking in a particular area then knowing what some of the council rules regarding floor/space ratios, total building height, setbacks etc will aid you. These are easy to obtain by going onto the Councils website and downloading their LEP's and DCP's.
