Construction Cost Estimation Services
Our estimates are built on real-world experience, not guesswork - so Northern Beaches and North Shore homeowners enjoy fewer budget surprises, smarter early decisions, and smoother projects when you’re ready to build.
Confidence starts with a realistic budget
Clear, Reliable Estimates You Can Build On
he purpose of our cost service is to help align the design with the budget as construction documentation progresses. This way decisions that have cost implications can be assessed and decided on at an early stage rather than realising costs at a later date after time and money has been invested into a full set of design documentation.
Where limited documentation is available, we prefer to start the process by providing an independent and standalone planning and budgeting service to uncover the full scope of the project with the client and architect if necessary to determine as accurately as possible project costs. This enables the client, architect and builder to make key decisions regarding scope and budget early rather than later throughout the project.
What’s included
Construction estimating services for every stage
Review of initial project documentation and provide a high initial cost estimate. This estimate is achieved by way of comparison of actual costs on past similar projects having a similar scope of works and similar finishes.
Site and office meetings as required.
Any high level adjustments to the initial cost estimate as plans and documentation progress if required.
Discussions regarding building methodology, selection of materials and aligning correct sub-contractors with the works.
A detailed trade specific quote once documentation reaches CC stage and all project documentation is available. Includes preparation of trade specific scope of works, site visits by relevant trades and review of sub-contractor quotes as required.
Any other reasonable assistance throughout the development of final CC documentation.
Local knowledge. Smarter budgeting.
Designed for Northern Beaches & North Shore Projects
We’ve built across the Northern Beaches and North Shore for over 20 years, so we know how costs vary between sites, suburbs and specs. Our estimates are tailored to the realities of building in places like Freshwater, Mona Vale, Balgowlah, Pymble and Wahroonga.
We also understand what adds to the cost - from bushfire zoning and stormwater systems to DA requirements, site access, engineering specs and material delays. We plan around these factors so you’re not hit with surprises down the track.
It’s local knowledge, backed by real numbers and builder insight.
