Renovate or Rebuild in The Hills?

Recently bought a 40 year old 3 bed, 2 bath 2 garage house in Baulkham Hills on a 900sqm sloping land for around $1.1 million. There is a 10x5m in-ground pebblecrete swimming pool as well. This is for my own living now with a view to selling in about 10-15 years. The house is in its original condition and requires a lot of work. Need to renovate kitchen, bathrooms, floors, replace all doors, paint, roof restoration, external wall rendering, pool resurfacing/fencing, driveway, balconies. It will be nice to add a deck and pergola in the back. Adding an additional bed and rumpus will make the house more liveable.

I am guessing the renovations alone will set me back by $100k and extension of pergola, bed and rumpus will perhaps cost another $100k-$150k. If I knockdown and rebuild, site costs/council approvals/designs alone will perhaps be $150k given that there is around 2m front-to-back slope and around 1m sideways slope. The house is now slit-level with the garages being on ground level. After these costs, building a two storey project home of 40 squares will cost around, I guess, $500K.

Should I renovate or rebuild? Or, do something else that I haven't thought of? All ideas will be graciously received.

    Should I renovate or rebuild?

    it's a bit odd to ask these questions after a big purchase and not before. one can actually purchase a nice modern four bedroom in those suburbs for ~$1.5m.

    2153 was one of >30 postcodes in sydney that nab said was at risk of mortgage default last year.

      It's an enormous suburb with people from poorer backgrounds to professionals, such as doctors/lawyers.
      It also houses some of the smartest kids and people in the country.

      To be honest, on hindsight…. I have probably made an expensive mistake.

      Sounds like OP bought a house in the right area then - congrats!.

    Going by your math, wouldn't the better question be: do you want to spend $200-250K or $650K?

    • I guess I am thinking from a long term value creation perspective. It will be a shame if I have to lose money when selling in 10-15 years.

        It's hard to know what property prices will be doing in 10-15 years time! If you look at the last 10 years, property prices in the hills have doubled. Whether it continues this trajectory is anyone's guess and there are so many variables that will impact this. Yes, you will create more value with a knock-down rebuild as in 10-15 years time you will be selling a 10-15 year old house (versus 50+ years). But all this may be counteracted, depending on the market is prepared to pay for your property.

          Will definitely rebuild if budget allows. selling 20 year old house is more appealing than 60 year old house, of course unless yours is architecturally designed whatnot.
          Old houses have unknown potential issues-white ants/asbestos. With new build you can customise your new home to your liking and maybe even build more space- more rooms, separate entry for in-laws blahblahblah the list goes on.

    When don't you get a few quotes from some builders first? The information you glean could help inform your decision.

    When you renovate there are a lot of hidden costs. You pull up the floors and bang you find some issues that push up your budget. Remove the plaster from the walls and sometimes the same thing.

    Your $150K for plans, site costs etc seems very high

    • $150k came to me as a surprise too. This was the Metricon sales guy's preliminary estimate which includes knockdown, levelling out the construction area, council approval fees, planning etc. However, this is just a desk estimate without anyone coming to the site.

        Hmm, from OP's description, I would say a lot of that $150K would be for the site cut and/or fill required to level the land to accommodate the Metricon house. A combination of 1m cut and 1m fill or a 2m cut is a lot, especially in terms of retaining walls and drainage solutions.

        • Don't forget, with older houses, there could be asbestos as well so that will blow the budget even more

    Have you thought about subdivision? Get advice from the local council.

    To answer your question, I wouldn't rely on advice from builders like Metricon. Their designs are inflexible and don't account for the topography of the land i.e. the design is reliant on the land being completely flat and the property must be a certain width.

    I think if I had to choose, I would do a reno. You should ask around any family friends, colleagues, neighbours, etc. for recommendations for local builders.

    Sell it, give all the money away and backpack around India:)

    • Why India?

      • The underperforming rupee.
