Whether you are extending your home, building a new house, adding a granny flat, or renovating, you will need residential drafting services at some point in the process. In Australia, any building work that requires council approval must be accompanied by scaled, detailed architectural drawings — and even work that does not require a DA still needs construction drawings before a builder can price, permit, or build it correctly.
This guide explains what residential drafting services cover, when you need them, what the process looks like, and how to choose the right drafting company for your project in Australia.
What Are Residential Drafting Services?
Residential drafting services involve the preparation of architectural drawings, documentation, and plans for residential construction and renovation projects. A qualified drafter translates your ideas, site conditions, and council requirements into a set of accurate, scaled drawings that can be used for planning approvals, construction certificates, building permits, and on-site construction.
Residential drafting is distinct from architectural design — a drafter typically works from a brief, concept sketches, or an existing design to produce the technical documentation, while an architect develops the design concept from scratch. For most residential projects in Australia, a qualified building designer or drafting firm can handle the complete documentation without requiring a registered architect.
Types of Residential Drafting Services
DA drawings (Development Application drawings)
Drawings submitted to council for planning approval. Required for new dwellings, extensions above complying development thresholds, dual occupancies, and developments in heritage or sensitive areas. Typically include a site plan, floor plans, elevations, sections, and shadow diagrams. See our full guide to DA drawings in Australia.
Construction drawings (CC drawings)
Detailed construction documentation prepared after DA approval. Include full structural details, floor plans, elevations, sections, specifications, and engineer’s details. Required to obtain a construction certificate (CC) or building permit before work begins. These are the drawings your builder works from on site.
Complying development drawings
In NSW, QLD, and other states, certain types of residential development can be approved as complying development without a full DA — through a private certifier rather than council. Complying development drawings must demonstrate compliance with the relevant SEPP or state code to the certifier’s satisfaction.
Renovation and extension plans
Plans showing proposed changes to an existing dwelling, including room additions, second-storey additions, carport or garage additions, deck and alfresco areas, and kitchen/bathroom renovations that affect the building structure.
Granny flat and secondary dwelling plans
Drawings for secondary dwellings, studio apartments, or detached granny flats. Requirements vary by state and council. In NSW, granny flats up to 60m2 may qualify as complying development under SEPP Housing; in Queensland, secondary dwellings up to 80m2 may be code assessable under the Queensland Development Code.
As-built drawings
Documentation of existing structures, either for council records, insurance purposes, or to provide a base for future renovation planning. Particularly useful for older homes where no drawings exist.
When Do You Need a Residential Drafter?
You need residential drafting services whenever your project requires:
- A development application (DA) or complying development certificate (CDC) from council or a certifier
- A construction certificate (CC) or building permit before work starts
- Plans for your builder to accurately price and quote the work
- Formal documentation of an existing building
- Plans for a building loan or owner-builder permit
Even for projects that do not formally require council approval, having proper drawings prepared by a qualified drafter reduces the risk of costly errors, ensures your builder works to a consistent specification, and gives you documentation for future property sales or renovations.
What Information Does a Residential Drafter Need?
To prepare residential drawings, a drafter will typically need:
- A copy of your certificate of title and deposited plan (to confirm boundaries and easements)
- A current survey or site measurements if no survey exists
- Your brief — what you want to build, how many rooms, intended use of each space
- Any sketch ideas or inspiration images you have collected
- Information about existing structures on the site (or access to measure them)
- Your council’s name (so the drafter can look up relevant planning controls)
The Residential Drafting Process
1. Initial consultation and brief
The drafter discusses your project requirements, budget, and timeline. They will review your site, check relevant planning controls, and advise on the most appropriate approval pathway — DA, complying development, or building permit only.
2. Concept plans
Initial floor plan layouts and rough elevations are prepared for your review and feedback. This is where the design is refined — room sizes, orientation, layout, and external appearance are confirmed before detailed documentation begins.
3. DA drawings (if required)
Once the design is confirmed, a full set of DA drawings is prepared and submitted to council with the development application. The drafter typically manages the lodgement process and responds to any council requests for additional information during the assessment period.
4. Construction drawings
After DA approval, the drafter prepares detailed construction documentation including structural details (coordinated with an engineer), specifications, and any specialist drawings required for the construction certificate application.
5. Construction support
During construction, the drafter is available to clarify drawings, issue amendments, and prepare any additional documentation required by the builder or certifier.
How Much Do Residential Drafting Services Cost in Australia?
Costs vary by project scope and complexity. As a general guide for 2026:
| Project type | Typical cost range (drawings only) |
|---|---|
| Granny flat / secondary dwelling | $800 – $2,500 |
| Single-storey extension | $1,500 – $4,000 |
| New single dwelling | $3,000 – $8,000 |
| Dual occupancy / duplex | $4,000 – $10,000 |
| Two-storey addition | $4,000 – $12,000 |
| Townhouse development | $8,000 – $20,000+ |
These figures cover drafting and documentation fees only. Additional costs may include council DA fees, engineering reports, surveying, energy assessments, and BASIX or NatHERS reports where required.
Choosing a Residential Drafting Company in Australia
When selecting a residential drafting company, look for:
- Local experience — familiarity with your state’s planning framework and specific council’s DCP is essential
- Clear fixed-fee quotes — avoid companies that quote hourly rates for documentation work without an upfront scope
- Portfolio of comparable projects — residential extensions, granny flats, or new dwellings similar to your project
- Good communication — responsive to questions and clear about the process and timeline
- Owner-builder experience — if you are an owner-builder, ensure the drafter has prepared drawings for self-managed projects before
Do I need a registered architect for residential drafting?
In most Australian states, a registered architect is not required for residential drafting. Licensed building designers and qualified drafting companies can prepare all necessary documentation for houses, extensions, granny flats, and medium-density residential developments. A registered architect is typically required for Class 2-9 buildings above certain scales. At Draftings Australia, our team of qualified building designers and architectural drafters handle the full documentation scope for residential projects.
Can a drafter prepare DA drawings without an architect?
Yes. In Australia, development application drawings for residential projects can be prepared by a licensed building designer or qualified drafting company without an architect. The key is that the drawings comply with your council’s submission requirements and applicable planning controls. Our team prepares complete DA drawing packages for residential projects across all Australian states.
How long does residential drafting take?
Timeframes depend on project complexity. Concept plans are typically ready within 3-7 business days. A complete set of DA drawings takes 7-15 business days for most residential projects. Construction drawings follow after DA approval and typically take 10-20 business days. We offer priority turnaround for time-sensitive projects.
What is the difference between a drafter and an architect for residential projects?
An architect typically leads the design process from concept through to completion, offering creative design input, project management, and construction administration. A drafter focuses on producing the technical documentation from a client brief or existing concept. For most standard residential extensions, new houses, and granny flats in Australia, a qualified building designer or drafting company delivers the same approval-ready documentation at a significantly lower cost. We recommend engaging an architect for complex heritage, high-end custom, or multi-storey projects where design guidance adds clear value.
Do I need a BASIX certificate for my project?
In NSW, most residential development applications require a BASIX (Building Sustainability Index) certificate demonstrating compliance with energy and water efficiency requirements. BASIX applies to new dwellings, additions over $50,000, and alterations to swimming pools. Our team can coordinate BASIX assessment and incorporate the required commitments into your DA drawings. Similar requirements apply in other states through NatHERS or equivalent sustainability frameworks.
Draftings Australia provides residential drafting services for homeowners, builders, and developers across Brisbane, Sydney, Melbourne, Perth, and Gold Coast. From a granny flat to a full new dwelling, we handle the complete documentation package.
