Consultant fees

What are some of the planning costs and fees to expect for a typical project


Along with architectural drawings, numerous other third-party consultants are required to support your application for approval to build. Below are some of the listed fees and consultant reports usually required that go into your Preliminaries


You will need a survey of your block of land. Currently, if you are applying for DA (Development Approval) or CDC (Complying Development Certificate).

(Approximate Cost $1000-$2500)


Section 149 certificate

A Section 149 certificate is a zoning certificate that is generated by the local council, which is specific to the property in question.

(Approx. cost $53)



A Geotechnical report is effectively a report on the soil make up of your block of land and is usually required for 2 reasons. 1. For structural engineering.
2. For effluent management (if the land is not serviced by council sewer)

(Approximate Cost $700-$2000)


Flood study/Hydraulics Engineer

A flood study may be required by council if your block of land lies in a low-lying area.

(Approximate Cost -This can be quite expensive)


Bushfire Protection Assessment

Most councils have facilities on their websites to check if your block of land falls into a fire-affected zone. If it does, then you will need a “Bushfire Protection Assessment”. This report will be submitted with your D.A. and will recommend a ‘Fire Rating’, the higher the rating the more special requirements that will be placed on your building project, these will increase the cost of building your house.

(Approximate Cost $500)


BASIX report

A BASIX report assesses both the energy and water consumption of your proposed building project. A minimum requirement must be achieved in both areas. Even though this may appear to introduce some restrictions on design and materials, it is a direct reflection of your ongoing “running costs”. This report will be submitted with your D.A.

(Approximate Cost $500-$700)


Landscape plan

Some councils will require a landscape plan to be lodged with development application drawings. Check the subdivision requirements in your land sale contract or you may wish to have a landscape plan drawn for your planning purposes.

(Approximate Cost $300+)


Council D.A. fees

In N.S.W. there are two processes through which a project passes before it is approved for building work to commence. The first of these is called a Development Application (D.A.) and is an approval process carried out by your local council. Fees vary from council to council and are related to project cost. Sometimes if the project is a ‘Complying Development’, the CDC. process may be carried out by a private certifier.

(Approximate Cost $1000-$6500). Note: D.A. fees run on a sliding scale that relates to the estimated project construction cost.


C.C fees/Private Certifier

The second approval process is a Construction Certificate (C.C.) and may be carried out by council or an approved certifier.

(Approximate Cost $500-$3500)


Long Service levy

The long service levy is a fee payable to the Building Services Corporation and is

0.35% of project value and must be paid before the C.C can be released.


Drawing & professional fees

Depending on what you are building, The Perfect Space will organise necessary consultants such as: Architectural drawings

(Approximate Cost $5000+)


Structural Engineer

A structural engineer is a professional civil engineer that has a specialised understanding of the forces and loads in structures that include bridges, buildings and tunnels. Residential structural engineers specialise in the design of residential buildings including houses and units.

(Appoximate Cost is $1500+)



An arborist, tree surgeon, or (less commonly) arboriculturist, is a professional in the practice of arboriculture, which is the cultivation, management, and study of individual trees, shrubs, vines, and other perennial woody plants in dendrology and horticulture.
