What it costs to build a custom home in Sydney's eastern suburbs

It is almost always the first question, and it deserves an honest answer. The honest answer is that there is no single number, because no two builds are the same. What there is, is a clear set of things that decide where your cost lands. Understand those, and the question stops being a mystery.

Here is what actually drives the cost of a custom residence in the eastern suburbs.

The site comes first

In the east, the land does more to your budget than almost anything else. A flat, accessible block is one thing. A narrow site on a steep street, with rock to excavate, retaining walls to build and barely room for a truck, is another entirely.

Access alone can move a budget. Many eastern suburbs streets are tight, and getting machinery, materials and trades onto a constrained site safely takes planning and time, both of which carry cost. Add a sloping block, rock, a basement or a pool cut into the hill, and the figure rises before a single wall goes up.

This is why two homes of the same size, one in a flat suburb and one on an eastern suburbs clifftop, can cost very differently. The design is only part of the story. The site writes the first chapter.

Size and scale

The simplest lever is floor area. More space costs more to build, and a larger residence carries more structure, more services and more finish across every room. Scale also compounds. A second or third level, a basement, or a large span that needs serious engineering all add more than their floor area suggests.

The level of finish

This is where a custom residence separates from a standard build, and where budgets stretch the most. Natural stone, bespoke joinery, large-format glazing, fine metalwork and considered detailing throughout cost more than off-the-shelf equivalents, by a wide margin.

The finish is also where your money is most visible. It is the difference you live with every day, so it is worth deciding early what matters most to you, and shaping the budget around it rather than discovering it halfway through.

Structural and design complexity

A simple form is cheaper to build than a complex one. Cantilevers, curved walls, double-height voids, large openings and pools all ask more of the structure and the trades. None of this is a reason to avoid ambition. It is a reason to know, at design stage, what each move costs, so you choose the ones worth it.

The line items people forget

Beyond the build itself sit costs that catch owners out. Demolition on a knockdown rebuild. Consultants and reports for the approval. Landscaping, pools and driveways. Service connections. In the east, the heritage and approval path can add design and documentation time, which is real cost even before construction starts.

Why a single quote so early can mislead

A number given before the design is grounded in the site is a guess. Custom builds blow their budgets for almost the same reason every time. The design and the construction were never reconciled early, so by the time the gaps surfaced, every fix had become an expensive one.

This is the quiet advantage of a design and build firm. Because our construction team informs the design from the first sketch, the budget is built on what your site and your design actually require, not on an optimistic estimate that unravels later. You get cost certainty earlier, and far fewer surprises once you are committed.

How SHORE approaches cost

We start with your site and your brief, not a template. We design knowing what each decision costs to build, so you can spend where it matters to you and save where it does not. One firm, one budget, one team accountable for holding it from concept to handover.

The clearest next step is a conversation about your site and what you want to build. From there, a real figure replaces a guess.
