FAQ’s
These are the two easiest ways you can contact us to obtain a quote.
- You can download our first floor addition packages. The packages will provide you with an initial indication on build costs for our standard packages.
- Already have plans? Simply complete this form and provide us with key details about your project, including the number and type of rooms, your preferred materials, budget and timeframe. You can also include supporting documents, such as existing plans or approvals (DA/CC/CDC).
We’ll contact you to arrange for our building consultant to come out to meet with you at your home and to prepare a detailed quotation on your proposed build.
It varies based on your project’s specific requirements. We typically consider factors such as room type and size, chosen materials (brick, cladding, tiles) and allowances for finishes like internal fixtures. Discuss your requirements with our building consultant, and we’ll provide you with a detailed estimate.
The typical build time is around 14 to 16 weeks for a standard 70m² first floor addition. Larger projects or those with more complex inclusions may take longer, and external factors such as weather conditions or supplier delays can also impact the timeline.
For safety reasons, you’ll need to vacate your home during the demolition and floor frame installation stages of the first floor addition, as power will be disconnected for approximately two weeks. Once this critical phase is complete, you may choose to return while the remaining work is carried out. Safety is our top priority, and any potential risks will be clearly communicated throughout the process.
Absolutely. During the planning process, a structural engineer will assess your home to confirm it can support the addition. If necessary, they may recommend additional steel to reinforce the new upper level.
Unfortunately, no. Steel-framed homes must be designed for two storeys from the start, as they cannot support added loads after construction.
