If you have a place for the cranes and concrete pump, then you should be good. Also, you can always go with mini-cranes too - there are number of options. Other than that if you are talking about double brick house, it is just about knocking down and removing roof and roof frame (expect a lot of waste here), installing metal beams and then either timber or pour the suspended slab (check out Speed Floor system), scaffolding and then it is not much different from the normal house building process - you pay for the walls, windows, new roof framing and roof, extend your services and complete internal finishes. In the worst case you would need to re-render your older walls to match the style. Unless some serious changes will be required on the foundation level (e.g. the house adds more weight, you would need to ensure that your footings will be able to hold that weight) - and this is where the additional big costs can come (lifting the house and re-doing footings is not an easy job). You would need to prepare all your drawings, decide on your finishes, do the structural engineering and then approach the builders for the exact quotations, not the ballpark estimates. You can also engage quantity surveyor in order to better understand the costs involved. Considering that the most time consuming and unpredictable costs are generally associated with site works and earthmoving, your quotations should be in $1.5-2.5K per sqm range depending on the level of finishes you are expecting. This side of the bridge alexp79, you'd be looking at more like 2.5 - 3K per sq metre to start with then level of finish and how much work to be done on the existing structure added to that as you mention. Stewie Re: 2nd floor additon in Sydney's lower north shore 9Jun 20, 2019 12:07 pm echelon6 HI all. Lots of conservation area houses in the lower north shore around Artarmon / Chatswood / Roseville - many of these undergo a massive 2nd storey addition and extension toward the back, as well as a rejuvenation of the front (paint, replace old timber features, maybe even cement render entire brickwork). How much would such a renovation, typically, cost? I know it's a difficult question to answer, depends on a lot of things, but really just after an empirical range answer. Alternatively I'm asking 'what do people typically spend on such a renovation?' 500k? 1.2m? I know it's probably between these two haha... E.g. to start with - 3br single storey double brick, original condition everything. To finish - extension upward (2nd storey added) and towards rear, new roof so there's no difference in tiles, cement render all bricks so can't see new/old mismatched bricks, new bath, new kitchen, new floors throughout (e.g. tile downstairs, floorboards upstairs), repaint. Exclude landscaping. Just after an estimate, or if you've done it yourself or know someone who has, actuals would be great. It would help me work out how much I'd like to pay for these types of properties. Thanks I live if the exact part of the world that you have described and I have two friends who have done what you described. One at middle cove who spend just under $1m and another at West Lindfield who spent $870k. I am also building a brand new house in the same area so I believe I have a pretty good handle on costs. Adding a second story is a very complex and slow process, you would spend the same building a 400sqm new house.
