Compare my quotesBuilding a house in South Africa — common questions
How much does it cost to build a house in South Africa, per square metre?
It depends heavily on your province, finish level (standard, high-end or ultra-premium), floor area and build complexity — provincial averages can range from roughly R9,000 to R17,000 per square metre (m², also written sqm). QSBridge turns your floor area, finish level and options into a trade-by-trade estimate in minutes, so you can see roughly where the money goes.
How do I compare quotes from building contractors in South Africa?
Start with a budget breakdown so you know roughly where the money goes. Give every contractor the same plans and the same list of what to include, so the quotes can be compared fairly, then use our Quote Checker to compare what they send you.
What is a Bill of Quantities (BOQ) and do I need one?
A Bill of Quantities (BOQ) is an itemised list of the quantities and rates in a build, trade by trade. It is prepared by a quantity surveyor from the plans and is what contractors price from. QSBridge does not produce a BOQ. It gives you a budget breakdown by trade from your house size and finish level, which is a good starting point for planning, but not a substitute for a quantity surveyor's work.
Do I need a quantity surveyor before I build?
A registered quantity surveyor's work goes well beyond a quick price — it's detailed, professional work that takes time and costs accordingly. QSBridge gives you a starting, AI-priced estimate in minutes — it's for budget planning only, not a substitute for that service. We recommend comparing it against quotes from a few contractors, or a professional QS, before you commit.
