The cost of building a house in Sydney ranges from $2500 to $7000 per square metre. Many factors influence the price, including location, block type, and design choices.
Firmus Building specialises in residential and small commercial projects around Sydney, including new homes, duplexes, alterations, additions and renovations. We can build from your approved plans and specifications or guide you along the process from conception.
As a family-run business, we take great pride in offering transparent quotes to give you the best idea of the costs involved. When we present a quote, we itemise every known element, and where we can’t put a cost, we’ll bring it to your attention.
Our process includes a thorough consultation, detailed planning, regular progress updates, and final inspections to ensure that the project meets your expectations. Our clients tell us communication is one of our greatest strengths, and we agree.
Project timelines vary depending on scope and complexity.
We’ll provide you with a timeline estimate based on your specific project during our initial consultation stage. While we make every effort to keep on track, project timelines can change thanks to external factors and scope change. If anything unexpected happens, we’ll inform you at the earliest possibility to manage expectations.
Yes, changes can be made, but they may affect the project timeline and budget. We work closely with you to accommodate changes and ensure that all adjustments are documented.
