Building a home is exciting. It starts with a vision, a Pinterest board, and a rough budget that feels very sensible at the time. Then reality steps in wearing steel-capped boots. Understanding what actually affects residential build costs can save stress, surprises, and those “how did we get here?” moments. At Prescom, we believe informed clients make confident decisions, and confident decisions lead to better builds and happier homes.
A brief look back shows us how much homes have evolved. Early Australian homes were simple, practical, and built with what was nearby. Over time, homes became larger, smarter, and far more detailed. Today’s residential builds include energy efficiency rules, complex approvals, specialised trades, and higher expectations for comfort and design. While this evolution has given us better homes, it has also added more moving parts that influence cost.
Bigger homes, higher ceilings, and custom layouts require more materials, more labour, and more time.
Sloping blocks, poor soil, tight access, or demolition works can add costs before construction even begins.
Structural materials, roofing, windows, joinery, and finishes all vary widely in price. A small upgrade repeated many times adds up quickly.
Skilled sub-trades are essential for quality work. Availability, complexity, and time on site all influence labour costs.
Council approvals, certifications, engineering, and inspections are required and must meet NSW building regulations. These steps protect homeowners but also form part of the overall budget.
Changes during construction are possible, but they often come with additional costs due to rework, delays, or reordered materials.
Here’s a fun fact many people don’t realise. Construction costs are not just about what you see. A large portion of the budget goes into what’s behind the walls, under the slab, and above the ceiling. Structural integrity, waterproofing, and compliance work are the unsung heroes of a well-built home. Another fun one is that the average home today contains more services and technology than homes built even 30 years ago, which means more planning and coordination behind the scenes.
Understanding build costs isn’t about cutting corners. It’s about making informed choices that align with your goals, lifestyle, and long-term value. At Prescom, we work closely with clients and sub-trades to plan properly, communicate clearly, and deliver homes that are built right from the ground up.
“A well-built home starts with a clear understanding, honest planning, and respect for every detail.”

Prime Costs (PC) and Provisional Sums (PS) are essential terms in construction quotes. Prime Costs cover allowances for materials like fixtures or appliances that haven't been selected yet, offering flexibility but potentially leading to additional costs if more expensive options are chosen. Provisional Sums are estimates for work not fully defined when quoting, like excavation or retaining walls, and may change due to unforeseen circumstances. Understanding the distinction helps homeowners manage budgets and avoid surprises during the building process.

A pre-handover inspection is crucial when taking possession of a new home to ensure any issues or defects are addressed before the final settlement. Key areas to check include the structural integrity (e.g., walls, floors), fittings and fixtures (e.g., taps, doors, windows), kitchen appliances, bathroom tiles and plumbing, electrical systems, and finishes like paintwork and flooring. By thoroughly inspecting these aspects, homeowners can prevent costly repairs later and ensure a smooth transition into their new home.
