A double storey design stacks living space over two levels, which lets you fit more floor area onto a smaller or narrower block without giving up your backyard. A single storey design puts everything on one level, no internal stairs, which generally means simpler structural engineering and easier accessibility. Which suits you better usually comes down to your block size and how your household wants to live.
Generally yes, per square metre, mainly due to the extra structural steel, staircases, and scaffolding involved. In Melbourne, a standard five-bedroom double storey home through a project builder typically starts from around $420,000–$480,000 for the build alone, with custom designs and premium finishes running higher. We provide a fixed-site-cost, transparent quote early in the process so you know exactly what’s included before committing.
Yes, narrow blocks are one of the strongest use cases for building double storey, since you get the floor area you need without sacrificing outdoor space. We assess your specific block during the initial consultation, including staircase placement and circulation, rather than forcing a fixed floorplan onto a site it wasn’t designed for.
Yes, every double storey design is planned around Victoria’s current 7-star NatHERS and Whole-of-Home requirements from the layout stage, factoring in orientation, glazing, and insulation across both levels rather than treating energy compliance as a late addition. Your specific rating outcome depends on your final block and design choices, which we work through with you during design.
Double storey builds generally take a little longer than single storey due to the additional structural work involved, so we don’t quote one guaranteed figure upfront. Aamico’s build promise is centred on transparent, realistic timeframes, we’ll confirm a schedule specific to your project once your design, approvals, and selections are locked in.
Absolutely, this is one of Aamico’s genuine specialties. We can design a double storey home with a ground-floor bedroom and bathroom, separate living zones, and privacy-conscious layouts for extended family, informed by real cultural understanding rather than a generic add-on room.
