A beautiful concept drawing is not yet a buildable home. Before a shovel reaches the ground, decisions about structure, waterproofing, planning controls, services and documentation can determine whether your project runs with discipline or becomes an expensive series of compromises. The right questions to ask architect before building help turn a vision into a home that can be priced accurately, approved efficiently and built to last.
For a custom home, knockdown rebuild, major renovation or dual occupancy project in Melbourne and regional Victoria, the architect should be part of a coordinated project team. Their design expertise is fundamental, but so is early input from a builder who understands site conditions, trade sequencing, compliance and the real cost of construction.
Start with the brief, site and budget
How will you test whether the design suits our site?
Every site has constraints. Slope, orientation, overlooked areas, easements, existing services, bushfire risk, flood overlays, soil conditions and local planning controls can all change what is sensible to build. Ask your architect how they will investigate these issues before settling on a preferred concept.
A strong response should go beyond sunlight and street appeal. It should address where the home sits, how water moves through the site, likely excavation requirements, access for trades and materials, and whether the design creates difficult junctions that add risk during construction. A narrow inner-suburban block and a sloping regional site need very different solutions.
What is the construction budget, and how will you design to it?
This is the question that protects the whole project. Be clear about whether your budget covers demolition, consultants, permits, site costs, construction, landscaping, driveways, pools, window furnishings and contingency. Many projects become strained because the design budget and the actual project budget were never separated properly.
Ask how the architect will check cost as the design develops. A preliminary estimate can be useful, but it is not the same as a builder pricing complete documentation. The more specific the plans, engineering and finishes are, the more confidence you can have in the numbers.
There are legitimate trade-offs here. A dramatic cantilever, extensive glazing or complex roof form may be worth it for the result you want. But you should know its cost, structural implications and maintenance demands before it becomes embedded in the plans.
Can you explain where the design is likely to cost more to build?
Good architects should be comfortable discussing buildability. Ask directly about features that need specialist trades, unusual structural solutions, custom fabrication or difficult waterproofing details. These are not automatic reasons to reject a design. They are reasons to make informed decisions.
For example, flat roofs, concealed box gutters, level internal-external thresholds and large openings can look exceptional when they are detailed and constructed properly. They also require precise falls, flashing, drainage and trade coordination. The unseen work is what keeps the finished home performing long after handover.
Questions to ask an architect before building in Victoria
Will the project need a planning permit, and what is the approval pathway?
In Victoria, planning requirements depend on the property, council controls and scope of works. Heritage overlays, neighbourhood character provisions, vegetation controls, bushfire management overlays and restrictions on title can affect the process. For dual occupancy, the planning pathway and associated servicing requirements can be particularly significant.
Ask whether planning advice or a town planner is required, what reports may be needed, and what the likely timeframe is. An architect cannot guarantee a council outcome, but they should explain the risks, the process and the points at which the design may need to change.
Also ask what happens if council requests amendments. Clarify whether this work is included in the agreed fee and how additional design time will be managed.
Who will coordinate consultants and construction documentation?
A home cannot be built from floor plans alone. Depending on the project, documentation may include structural engineering, soil testing, energy rating assessment, civil and hydraulic design, electrical layouts, joinery drawings, landscape plans, BAL requirements and specifications for finishes and fixtures.
Ask who appoints these consultants, who checks that their information aligns, and who is responsible for resolving conflicts between drawings. A structural beam that clashes with a window, or a drainage route that has not been considered early, can create delays and variations on site.
The same applies to the building permit. Confirm who prepares the information required for the building surveyor, who responds to requests for further detail, and what is included in the architect’s scope versus the builder’s scope.
What level of documentation will be issued for pricing and construction?
This is one of the most practical questions you can ask. A planning set may be enough to seek council approval, but it is rarely detailed enough to obtain a reliable fixed-price building contract. Before asking builders to price the work, you need to understand exactly what information they will receive.
Ask whether the documents will show key construction details, room finishes, wet-area layouts, door and window schedules, ceiling heights, external materials, joinery, lighting intent and appliance allowances. If an item is not documented or specified, it is more likely to become an assumption, allowance or later variation.
Complete documentation does take time and professional fees. In most substantial projects, that investment is far less costly than building from incomplete information.
Establish how architect and builder will work together
When should we bring the builder into the process?
The earlier the better, particularly for a complex renovation, constrained block, sloping site or architect-designed home with detailed finishes. Builder input during concept and design development can test whether the construction method is practical and whether the budget is tracking realistically.
This does not mean the builder should dilute the design. It means the design team can make informed choices before expensive documentation is complete. A disciplined builder can flag access issues, structural complexity, drainage risks, likely lead times and details that need clearer resolution.
At Builda Group, this early coordination is central to design-and-construct and architect-led work. The focus is not simply on making a price fit. It is on protecting the integrity of the design while ensuring the home can be built properly, inspected at each stage and delivered with clear accountability.
Will you review the builder’s quote and proposed substitutions?
Ask whether your architect will assist through tender or pricing. They may be able to compare quotes, identify exclusions and check that each builder has priced the same scope. This is valuable because a lower figure may reflect missing work rather than a better outcome.
Clarify how substitutions will be handled too. Sometimes a selected product is unavailable, over budget or unsuitable for the intended application. The process should require a clear explanation of the alternative, including its appearance, performance, warranty and cost effect. Substitutions should never be treated as an afterthought.
What site involvement do you provide during construction?
Architect involvement can range from occasional inspections to full contract administration. Ask how often they will visit site, what they will inspect, how issues will be recorded and whether they have authority to assess variations or certify progress claims.
This needs to be clear because the architect, builder and building surveyor each have different roles. A building surveyor assesses prescribed regulatory matters. The builder manages construction quality and trade coordination. An architect may review whether the work generally aligns with the design intent. None of these responsibilities should be assumed.
Protect decisions before signing a contract
What is included in your fee, and what may cost extra?
Request a written scope that identifies each design stage, the number of concept revisions, consultant coordination, permit support, interior selections, tender assistance and construction-phase services. Also ask about hourly rates or additional fees if the scope changes.
The aim is not to demand unlimited revisions. It is to understand the decision points. A clear scope helps everyone move forward without disputes when the brief changes, extra meetings are required or planning conditions introduce new work.
What decisions must be finalised before we seek a fixed price?
A fixed-price contract is only as reliable as the information behind it. Ask the architect and builder which selections need to be locked in before contract signing, and which can reasonably remain as defined allowances. Items such as tiles, tapware and appliances can sometimes be managed as allowances, but structural elements, major finishes and complex site works need more certainty.
You should also ask how variations will be documented once construction begins. The right process is simple: identify the change, explain the cost and time impact, obtain written approval, then proceed. Verbal instructions are a poor foundation for a major investment.
Who owns the drawings, and can they be used with another builder?
Architectural drawings are intellectual property. Confirm the licence you receive, whether it allows you to use the documents to obtain quotes, and what happens if you change builder or pause the project. It is a straightforward question that can prevent friction later.
The best architect is not only the one who produces an impressive concept. It is the professional who can explain the implications of every key decision, coordinate openly with your builder and document the home well enough for it to be built without guesswork. Ask the hard questions early, when changes are still lines on paper rather than expensive work on site.
