Setting a realistic budget for an architect-designed home

Start with the whole picture

Most people think of their budget as the cost of building. A complete project budget usually includes:

• Construction: the builder's price for the work itself
• Professional fees: architect, structural engineer, land surveyor, energy rating and any specialist reports
• Permits and approvals: planning and building permits, and council or authority fees
• Contingency: an allowance for things that only appear once work begins
• Fit-out and landscape: furniture, window furnishings and garden, if they're not in the builder's scope

Knowing all of this upfront avoids the most common surprise: a build price that fits, and a total project cost that doesn't.

What drives cost

The size of the home matters, but it isn't the only factor. Cost is shaped just as much by:

• Complexity: structural changes, steel, excavation and second storeys
• The existing house: older homes often need underpinning, rewiring or replumbing
• The site: access, slope, soil and neighbouring buildings
• Finishes: joinery, stone, glazing and fixtures can vary widely

A well-planned smaller home often feels larger and costs less than a bigger one that isn't working as hard.

Where to spend

We'd rather put the budget into the things you use and feel every day: good light, a plan that flows, joinery that does real work, and materials that age well. Those are hard to change later. Some finishes can be upgraded down the track.

How we keep design and budget aligned

We ask for a realistic budget at our first conversation, and treat it as part of the brief. From there:

1. Feasibility and concept: we test the scope against your budget before the design goes too far.
2. Design development: cost is checked as the design develops, so decisions are made with the numbers in view.
3. Documentation: detailed drawings and specifications mean builders price the same project, with fewer surprises once building begins.

Questions we're often asked

Should I tell my architect my real budget?

Yes. A clear figure helps us design the right home, not a version that has to be cut back later.

How much contingency should I allow?

It depends on the project. Renovations of older homes usually need more than new builds, because more is hidden until work starts. We'll suggest an allowance once we understand the house.

Can you tell me what my project will cost before we start designing?

We can give a realistic view of scope and likely cost early, through a feasibility study. Firm pricing comes from builders once the design is documented.
