Try not to use this method for your renovation or custom home. There really is a mountain of things that will affect your square meter cost. You will likely be disappointed if you attempt to estimate your costs based on some online tradies forum stating the average square meter rate. We recommend finding out what your budget is, so first on your list should be to visit the bank and see what you financially do, then get a reputable builder and/or architect to walk through your ideas and provide an initial rough estimate based on feasible solutions.
Time is money in any business, so expect to pay for someone’s time to complete a quote for you as well as any variations along the way. A reputable builder will request a fee to cover these expenses as it genuinely takes hours and hours to complete a detailed quote, just right for you.
Be sure to talk to your builder through the design process and be honest about your budget. It is the only way to accurately ensure you avoid disappointment after weeks of planning and designing, only to find out that you have over-run your budget and need to cut back on your dream design. Which anyone whom has renovated or built new will tell you it is sooo hard to compromise on your dream.
