We're currently in the throws of designing a single story house with an architect and I'm having some trouble getting a feel for what an average and large house is and how house sizes (area) are calculated. Are house sizes, when advertised via real estate agents etc., stated as the total living space under roof, not including the garage, pool, outdoor entertainment areas etc.?
A bit of background: We moved from Sydney to the Sunshine Coast last year and we've bought a large, beautiful block of land in the rural part of the Sunshine Coast. We previously owned and lived in a large 3 bedroom apartment in Manly which was around 240sqm with a 54sqm balcony.
We're in early concept stages and the total size of the main house is 275sqm. The total build area including living space, guest house (90sqm), pool, outdoor entertainment, garage, master bedroom balcony etc. is 575sqm. I'm mostly concerned about the size of the main house living area and my concern is that this feels like it's going to be too small/pokey especially coming from a large apartment.
Am I being unrealistic? I'm hoping there's some builders or others who've recently built on here who might be able to help provide some guidance of the area of an average sized home (just living space) and a large home and are modern homes in Australia advertised per their actual living area?
