Choose a service that matches your project
When engaging a building designer, look for a clear match between your project and the proposed service. A new home, renovation, duplex and commercial project can involve different design questions and documentation needs.
Start with a discussion about your property, objective and budget. Ask the designer how they would approach the first stage and which information is needed before detailed plans. A useful response should explain the process in terms you can understand.
The fee is important, but a comparison needs more than the final number. Check the stages, deliverables, assumptions and exclusions. Two proposals can appear to offer the same service while allowing for very different amounts of investigation, coordination and documentation.
Understand what a building designer provides
Building design services may include feasibility, concept layouts, design development, approval drawings and construction documentation. Some engagements also include consultant coordination, application support or assistance with builder pricing.
These tasks should be listed in the proposal. Ask what you receive at the end of each stage and which decisions need to be made before the next stage begins. The distinction between a concept drawing, an approval set and a construction set matters when planning the whole project.
If you need interiors, detailed joinery or construction-stage support, raise those requirements at the beginning. They may be separate services. Do not assume that every drawing or later meeting is included in a general description such as complete plans.
Ask about relevant qualifications and experience
Ask the designer to explain their qualifications, current accreditation where applicable and professional insurance. Review examples that are relevant to your project type, including how the designer describes their role.
When reviewing images, distinguish completed project photographs from concept visuals. Attractive imagery can communicate design intent, but it does not by itself explain the scope of the designer's involvement or the construction outcome.
Discuss the practical challenges in your project. For a sloping site, ask how levels and consultant input would be investigated. For a duplex, ask how feasibility and the intended title outcome would be addressed. The discussion should show how the service relates to your site.
Decide whom to contact first
If you have a broad idea but have not checked the land, an initial designer or planning feasibility discussion can help organise the next steps. Where a particular planning issue is central, specialist town planning advice may be needed early. If CDC is being considered, eligibility feedback from the proposed certifier can inform the design.
A builder or estimator can provide useful pricing input once the scope is clear enough to explain what is being priced. A preferred builder may also identify construction considerations during design. These roles can complement each other when the information and responsibilities are clear.
For certification, remember that the certifier has an independent statutory role. NSW Government explains that certifiers assess legislative compliance and are not project managers or site supervisors. Read the official certifier role guidance.
Compare the scope before comparing fees
Ask whether the proposed fee covers investigation, concept development, approval documentation and detailed construction drawings. Confirm what meetings and revisions are included and how additional requests are charged.
Check consultant fees, authority charges, application fees and other third-party costs separately. Ask whether GST is included or added. If a proposal contains allowances, identify what they cover and what would change them.
Read our building designer cost guide for the broader cost discussion. When comparing quotes, use the same brief and requested stages. A lower fee for an earlier drawing stage cannot be compared directly with a proposal that includes later documentation.
Clarify coordination and application support
If you want someone to organise the process, ask what coordination means in the engagement. It may involve obtaining consultant proposals, issuing current plans, reviewing the relationship between documents and supporting the application.
Ask who commissions and pays each consultant, who keeps the drawing revisions current and who responds to council or certifier requests. Clarify how additional reports or design changes are handled if they arise later.
NSW Planning Portal support should also be described in the scope. Confirm whether the service includes preparing and uploading documents, monitoring requests and coordinating responses. Consultant coordination does not mean the designer personally supplies every specialist assessment or controls the approval decision.
Provide a useful brief for the quote
Prepare the property address and a concise description of the work. Include the number of dwellings or intended use, desired rooms and important features. Identify what must be retained and any parts of the brief that are flexible.
Provide your approximate construction budget and any target dates. Budget guidance helps the designer understand the scale you intend to pursue. A quote request that includes a large wish list but no budget can lead to a scope that does not fit your expectations.
For a development, explain whether the properties will be retained, rented or sold and whether separate titles are an objective. For a renovation, explain the current problems in the home as well as the extra area you want.
Share the available property documents
Useful information may include a survey, title and deposited plan, planning certificate, existing building plans, earlier approvals and relevant reports. Add photos that show the building, street and access.
Tell the designer which documents you do not have. That helps identify the investigations needed before a detailed quote or design stage. Do not alter old plans to imply that they accurately represent the current property if later work is uncertain.
If another designer has already prepared drawings, explain their status and your rights to use them. Discuss any review or further design work as a defined scope rather than assume an existing set can be adopted without investigation.
Agree how decisions and changes will be managed
Ask who your main contact will be and how design comments should be provided. Consolidated feedback can make the process easier to track, particularly where several owners or development partners are involved.
Review payment milestones, deliverable formats and the process for variations before accepting the proposal. Ask what happens if the brief or approval pathway changes. The purpose is to understand the service commitment, including where further work may be needed.
A clear engagement should help you know what to expect next. Approval itself depends on the application and relevant authority; it should not be treated as a promised outcome merely because design services have been commissioned.
