Browse Forums Building A New House 1 May 04, 2016 7:30 pm Hi all, Im new here and have quite a bit of reading to do through the topics here. It looks like I'm going to get a tonne of info from all of you and your experiences I just wanted to ask some questions about knock-down-rebuild as we are looking at this as an Option right now after finding it extremely difficult to find a decent house in within our budget. Firstly, how much does demolition in Sydney generally cost? We are in north shore. Second, do you get the demolition done as part of a KDR package with a company like masterton, Metricon, rawson etc, or do most people organise the demolition themselves? Lastly, from the time of purchasing the land, and then finding a builder, what is the standard time to construct a house, doing KDR? How long do you usually have to wait between signing a contract and having the demolition done? Thanks in advance! I'll be posting lots more questions in the near future, and looking forward to sharing my experience with you all Re: Question about KDR 2May 11, 2016 12:32 pm Bump. no one has any advice? or is there another thread you can direct me to that answers these questions? Re: Question about KDR 3May 11, 2016 1:56 pm Hey Witherwings, Generally you would organise your own demo and abolishment of services outside of the construction package from a project / volume builder. The same applies for smaller builders / custom builders. We are doing KDR at the moment; although in very early stages. Currently living in the house we'll knock down, and I'm not going to look for a rental / book in demo until we've gone through tender and signed the contract. The paperwork that I have states that we have at least 10 weeks until we have a contract ready for signing. In Melbourne, the average price for a demo (including asbestos) is between 15 - 20k. If you wish to salvage from the house, the price for demo may go up as demolishers make money from recycling bits of old houses and fittings. In terms of cost, completely understand about selling vs KDR as we've been considering these options for about 3 years now. You have to go in with eyes wide open and understand that site costs will most likely be higher for KDR, as the foundations always need extra support. However, stamp duty and tax normally outweigh site costs if you were to sell, anyway. Good luck. Re: Question about KDR 4May 11, 2016 3:25 pm We are in Brisbane, so costs are probably different, but we went to tender in Feb 2015, contract signed early May 2015, demo late May/early June 2015, construction started early September and handover is due tomorrow. I think knockdown rebuilds tend to take a little longer than new estate builds from what I've seen on this forum.

It does mean a bit of organisation though. Doing it yourself involves putting an application for demolition into council, but this shouldn't be very hard. You need to abolish the services: gas and electricity - these can be one of the biggest holdups, as they may want a month or more to do it. Demolition companies aren't always the most reliable, but will typically get the demolition done within a few weeks of demolition approval from council. So it would be reasonable to expect about an extra 2 months in the building cycle compared to vacant land. In Adelaide, the demolition cost is around $10k including asbestos, but I'd expect the Sydney price to be more in line with Melbourne as the cost of materials disposal would be higher. The soil classification will likely be worse than a new development site due to being disturbed with the old footings, so expect another $10k or so extra in more footings for the new house. Re: Question about KDR 6May 11, 2016 4:46 pm We are currently going through the KDR process and, as others have advised, you will need to organise the demolition contractor, abolishment of gas & electricity and cap your water & sewerage. We signed a building contract in December 2015, demolished in January 2016 and had a site start in March 2016. The logistics of booking a demolition date, organising abolishment of gas & electricity, finding a suitable rental property, organising removalists etc. in the right order and in a very short time frame, can be very time consuming.

Don't the foundations get removed and the land flattened? Re: Question about KDR 8May 15, 2016 8:00 am Yep - because you've removed the old foundations from the land, it means it's now disturbed. So then you have to build your new place with extra support in the disturbed land so they can't move as much. That's my understanding.

Re: Question about KDR 10May 22, 2016 1:42 pm When they dig up your old foundations the soil is disturbed and not "compacted" in the way the origional soil is. We had 59 concrete piers and some of our piers went down 2800 so that they were founded well in to the original undisturbed soil/clay. Our build thread viewtopic.php?f=31&t=82369&p=1525857&hilit=fairhaven#p1525857 We were lucky in that our old house was so small (86 square metres) compared to the new house, they were able to take enough readings around the old backyard house before… 8 37146 The biggest challenge will be if you take out a loan and then run out of money - you'll have an incomplete security and lenders do not like this so you can get stuck.… 2 19108 Hi, I am looking into doing a KDR in Melbourne and am contemplating using Kialla Homes. I am looking for feedback on them from others who have built with them. 0 13447 |
