Building Designer Review Checklist for NSW Projects

A building designer can turn a good idea into an approved, buildable project - or leave you with attractive plans that miss critical planning controls, omit key details and create costly changes later. This building designer review checklist helps NSW homeowners, investors and small developers compare designers on the matters that affect approval, price and buildability.

Choosing on fees alone is rarely the best move. The right fit depends on your site, project type, approval pathway and the level of support you need from concept through to construction documentation. A granny flat in a straightforward zoning area requires a different approach from a constrained renovation, duplex or small commercial fit-out.

Building Designer Review Checklist: Start With Relevant Experience

Ask whether the designer regularly works on projects like yours in your local area. General design experience has value, but NSW planning controls, council expectations and construction practices vary between project types and locations.

For example, a designer experienced in new homes may not be the best choice for a difficult addition to an older dwelling. Renovations require careful consideration of existing levels, structural interfaces, drainage, heritage constraints and how new spaces will work with the home you already have. Likewise, a duplex or townhouse proposal needs early attention to density, parking, private open space, landscaping, waste collection and overlooking.

Request examples of approved projects that are genuinely comparable. Look beyond the presentation images. Ask what approval pathway was used, what issues arose during assessment and how the design responded to the site. A designer who can explain these decisions clearly is more likely to give practical advice before time and money are committed.

You should also confirm who will actually manage your project. Some firms have a principal involved at the first meeting but transfer work to a different team member later. There is nothing inherently wrong with a team approach, provided responsibilities, review points and your main point of contact are clear.

Check Their Planning and Approval Knowledge

In NSW, the design and approval strategy should be considered together from the outset. A plan that appears to meet your brief may still be affected by zoning, setbacks, height limits, floor space ratio, heritage provisions, flood mapping, bushfire requirements, easements or minimum landscaped area.

Ask the designer to explain the likely pathway: a Council Development Application, a Complying Development Certificate, or another process relevant to your site. The answer should be measured. No responsible consultant can guarantee an approval before reviewing the property and applicable controls, but they should be able to identify the main questions early.

A useful discussion covers whether your proposal is likely to need variations, which reports may be required and whether a preliminary enquiry or site investigation is worthwhile. It should also cover the difference between development approval and the documentation required before construction can begin. These are separate stages, and assumptions about either can cause delays.

Be cautious if you hear that approvals are "easy" without a proper site review. A fast pathway can be a real advantage, but only where the proposal and property satisfy the relevant requirements.

Questions to Raise Before You Appoint a Designer

Use the initial consultation to obtain clear answers to the following points:

• Have you completed similar projects in this council area or a comparable NSW planning environment?

• What planning controls or site constraints should be checked before concept design begins?

• Is a DA or CDC likely to suit the project, and what could change that advice?

• Which consultant reports may be needed, such as survey, BASIX, bushfire, flood, geotechnical, acoustic or stormwater information?

• What drawings and documents are included for approval, and what additional documents may be required for construction?

• Who will coordinate consultant information and respond to council or certifier requests?

The purpose is not to test a designer on every regulation at the first meeting. It is to establish whether they have a structured process and can identify risk before it becomes an expensive redesign.

Review the Design Process, Not Just the First Concept

A well-presented concept is valuable, but it is only the starting point. Ask how the designer develops the brief, tests options and incorporates feedback. You want enough exploration to make sound decisions, without an open-ended process that continually adds fees and time.

Good concept planning should address orientation, privacy, access, storage, room sizes, natural light and the practical movement of people through the building. It should also consider the realities of your budget. A large glazed opening, steep site cut, complex roofline or cantilever may look impressive, but each can add construction cost and approval complexity.

For investment properties and secondary dwellings, assess the plan through the eyes of future occupants as well as the approval authority. Functional kitchens, sensible living areas, private outdoor space and straightforward access often add more long-term value than unnecessary visual features.

Ask whether 3D views are included and how they will be used. They can be helpful for understanding scale and layout, particularly for clients who find floor plans difficult to read. However, a 3D presentation should support the technical drawings, not replace careful documentation.

Examine Drawings, Documentation and Consultant Coordination

The level of documentation required depends on the job and the stage you are engaging the designer for. Approval drawings may be sufficient for a DA or CDC submission, while a builder pricing a complex custom home, addition or commercial project will need more detailed information to reduce assumptions.

Request a written description of deliverables. It should identify the plans, elevations, sections, schedules and reports included in the agreed fee. Clarify whether the scope covers demolition plans, site plans, shadow diagrams, finishes, external materials, drainage concepts and construction details where applicable.

Also ask how consultant work will be managed. A building designer may coordinate information from a surveyor, engineer, energy assessor, certifier and other specialists, but those consultants may be appointed and invoiced separately. That is common practice. What matters is knowing who is responsible for obtaining, checking and incorporating each piece of information.

Coordination is especially important where a project involves structural alterations, sloping land, drainage issues or fire safety requirements. A set of drawings is only as useful as the information behind it. Clear coordination reduces the risk of conflicting advice reaching the builder or approval authority.

Compare Fees by Scope and Risk, Not by the Lowest Number

A fixed fee can provide certainty, but read the proposal closely. Compare like with like: the number of design options, revisions, meetings, approval submissions, authority responses and construction-stage services can vary significantly between firms.

Ask what sits outside the quoted fee. Common exclusions can include consultant reports, application fees, certifier fees, additional revisions after sign-off, redesign caused by changed instructions and responses to unexpected council requests. These costs are not necessarily a concern, provided they are identified upfront.

It is also reasonable to ask about timing. A reliable programme should show when site information is needed, when concepts will be presented, when documentation will be completed and what approval timeframes are outside the designer's control. Council assessment periods and external consultant availability can affect the programme, so treat any promised approval date with care.

Look for Straight Answers and a Practical Working Relationship

Your designer will be interpreting your goals, explaining constraints and helping you make decisions with long-term cost implications. Technical ability matters, but so does communication. During early conversations, consider whether advice is direct, whether questions are answered in plain English and whether the designer is willing to explain trade-offs.

References and testimonials can offer useful context, particularly where they mention approval support, responsiveness and handling of issues. Still, the strongest indicator is often the quality of the initial advice. A designer who asks detailed questions about your site, budget, intended use and timeframe is doing the necessary groundwork.

Warning Signs Worth Taking Seriously

Be careful where a proposal has vague deliverables, unusually low fees with no stated exclusions, or assurances that approval is guaranteed. Other concerns include reluctance to discuss planning controls, a lack of comparable completed work, and pressure to proceed before basic site information is available.

None of these points automatically means a firm is unsuitable. There can be legitimate reasons for a limited scope or preliminary fee. The key is transparency. You should understand what you are receiving, what remains uncertain and how changes will be managed.

A considered appointment gives your project a stronger foundation. Before signing, make sure the designer's experience, approval approach, documentation scope and communication style suit both the property and the outcome you want to achieve.
