A two storey home gives you more living space for the same size block of land, since you can effectively double your living area. However, does it cost you much more to build a two storey home compared with a single storey house? In this quick guide to building your own two storey property, we look at what’s involved in building a two storey house and some of the stunning designs available.

Building a double storey house

Building a new double storey home gives you the opportunity to choose a floor option that suits your household, lifestyle, preferences, and needs, whether your land size is large or small. The optimal two storey design for you will also depend on factors like your block size and budget. If you have a smaller lot of land, you might need to consider which option you’ll prioritise; an extra room or more garden space.

A double storey home means you can make the most of your living space on a smaller block, because you can build vertically to fit more space onto a smaller block of land. If you have a large lot of land, a double storey house design also maximises your living space.

When it comes to budgeting, don’t underestimate your expenses, especially the finishing costs. Similarly, avoid unnecessary spending on luxuries that don’t raise the value of your home. Costs to factor in include:

  • Land – Your block of land could take up as much as 50% of the total budget, and that reflects how land values tend to increase consistently over time while the value of the actual structure declines.
  • Preparation costs – Site preparation can include demolishing old property, clearing away trees and other structures, and establishing retaining walls and levelling blocks. You might also need to lay water, power, sewer, and gas connections.
  • Construction costs – Your build contract will list inclusions, including design features and build specifications.
  • Finishing expenses – Internal and external finishes might not be included in your standard build contract and they can account for as much as 15% to 25% of your total budget. Examples of internal finishes include window treatments, wall painting, air conditioning, lighting, tap upgrades, and floor coverings. External finishes include landscaping, pools, and water gardens. Fences, gates, decks, paved lanes, and sheds are other examples of external finishes.

Single storey versus double storey

Building a two storey house might be cheaper than you expect, and if you’re just budgeting for the basics, it could even be cheaper (in per square metre terms) than a one storey home when basic costs – foundation, slab, frame, and roof – are accounted for. Factor in the cost of land, and a two storey home could be far more cost effective as it allows you to scale up and create more living space for the same spend on a land parcel.
