When you extend your home, you have two choices — out or up. Some homeowners shy away from adding on a second storey, thinking the cost will be prohibitive compared to a ground floor home extension. Is this really the case? How much does a second storey addition cost?
Adding a second storey is not a project you should take lightly because mistakes can be costly and dangerous. Depending on how extensive the renovation is, you can finish it in as little as 12 weeks for small additions or over a year for a larger and more complex layout.
So what are the benefits and costs of a second storey addition? Read on to find out.
Gain more living space without moving out
This is perhaps the greatest advantage of building a second storey, especially if you live in a location that you really love, somewhere that truly suits your lifestyle. By adding a second storey, you can gain additional living space without having to give up the perks and convenience of living in an area that has all the amenities, services, businesses, and opportunities that you need, want and enjoy.
With greater room, you and your growing family can live more comfortably. On top of that, additional space means that you can stay in the family home for the years to come, as there is enough space available for a multi-generational household.
How Much Does a Second Storey Addition Cost?
A second storey addition may cost less than a ground floor addition, but it can still represent a significant expense. Estimates vary, but a second storey addition is typically between $1,850 and $3,300 per square metre. A number of factors influence the cost of a second storey addition. The quality and price of construction materials and inclusions will make a difference and if the ground floor needs reinforcing to carry the load of the extension, it can add a substantial amount to the cost.
Choosing a Builder
Choose a home extension builder who specialises in or has extensive experience in building second storey additions. View their projects and reviews to uncover whether they can do a good job. A great builder also knows how to avoid disrupting your daily life as much as possible so you can keep on living while the build takes place wherever possible.
You need to be absolutely sure that they will work fast and efficiently; disrupt your daily life as little as possible; and respect your privacy while they work.
