Client guide 01 · Budget, site and design

Before you price.

The earlier construction costs are considered, the more opportunity there is to keep the brief and budget aligned.

Waiting until detailed architectural and engineering drawings are complete can mean significant fees have already been spent before discovering the home is over budget.

01

Check the budget early

Before detailed drawings
Establish your total project budget, not just the build budget
Cost-check the initial concept
Consider an elemental estimate from an independent quantity surveyor
Involve an experienced builder early
Agree when pricing will be reviewed as the plans develop
Leave enough flexibility to make changes if the estimate is too high
The aim
Understand whether the home you want and the budget you have are reasonably aligned before the design becomes expensive to change.
02

Understand your site

Two similar homes can have very different costs because of the site.

Some of the biggest project costs may never be visible once the home is finished.

Review
Ground conditions and foundations
Existing services or upgrades
Excavation and earthworks
Demolition
Retaining
Coastal exposure
Site access
Flood or natural hazard requirements
Drainage and stormwater
Crane, scaffolding and delivery access
03

Be careful with square metre rates

“What is your square metre rate?” is a common question, but it can be a poor way to estimate an individual architectural home.

Registered quantity surveyor Nick Clements of YourQS analysed 468 residential projects and found considerable variation in square metre rates, including between similarly sized homes.

He also notes that changing the shape and configuration of a home can create a 20 to 30% difference in the square metre rate, even when similar materials are used.

Before comparing $/m², ask
Is the site comparable?
Is the architectural complexity similar?
Are the foundations similar?
Is the specification comparable?
Are garages and covered outdoor areas included?
Are site works included?
Does the figure include GST?
Is the level of cabinetry, glazing and finishes similar?
A better question
Can the home I want, on this site, at the level of finish I want, realistically be built within my budget?

Allow for the full project cost

The builder’s proposal may not cover your entire project.

Professional costs
Architect
Structural engineer
Geotechnical engineer
Surveyor
Planner
Interior designer
Landscape designer
Quantity surveyor
Council and consenting fees
Check your architect’s agreement includes
Council Requests for Information
Amendments after consent
Construction queries
Site observations
Additional detailing during construction
Other costs
Landscaping
Driveways
Fencing and gates
Pools
Service connections
Window furnishings
Direct-purchased fittings or appliances

If it sits outside the builder’s proposal, it still needs to sit somewhere in your budget.

05

Bring construction knowledge in earlier

An alternative to waiting for completed plans is to involve your preferred builder during design. This allows the architect, engineer and builder to consider design, buildability and cost together.

A small change to a detail can sometimes reduce structure, materials or labour considerably.

How we approach it

Design, buildability and cost, considered together.

Our involvement can begin before you have an architect or once early concepts are underway. Pricing is reviewed as the plans develop so you can make informed decisions before reaching the point of no return.
