Why you need a second storey extension floor plan

If you’ve fallen in love with your home, you know how difficult it is to leave. For some families, growing out of a single storey home is inevitable. There’s just not enough space to prosper.

Fortunately, by creating a new second storey addition, you can remain in the home you love. By working with a design consultant from Supa Group, you can take your existing home and develop a floor plan that speaks to your lifestyle.

Benefits of a second storey floor plan

Adding a second storey presents an untold opportunity to future-proof your family home. With the right floor plan, you can create more space, improve on style, and add exponential value to your home.

By effectively doubling the square meterage of your home, you increase its living space and by extension, its liveability.

Floor plan inclusions

By adding another layer to your home, you can create more areas for communal living by adding a new kitchen and open plan living area. If you need a separate sanctuary, then a second floor plan can create a retreat for a master suite and children’s bedrooms.

There’s really no limit to what you can achieve within building permit regulations. If you have a dream floor plan for your second storey, contact Supa Group to bring it to life.

Are second storey extension permits difficult to obtain?

Not at all. During the contract phase of the build, we will seek all necessary local council building permits. Everything we build will be to spec and up to code. It’s our guarantee as a second storey extension builder.

Do I need to undergo a ground floor extension at the same time?

Not necessarily. We can create an entirely independent floor plan on the second floor of your home. In some cases, it will make sense to make some changes to your existing ground floor floor plan. It all depends on your current home and your vision for a redesign.

Will I get design input into my new floor plan?

Of course! We take pride in working with clients to develop their perfect floor plan, whether its for a two storey extension or a simple ground floor renovation. You’ll work through our design consults from the first consultation throughout the entire process.
