How Much Does It Cost To Draft House Plans?

Building or renovating a home is one of the biggest investments most Australians make, and getting the house plans right from the outset is critical. After three decades working with homeowners across Melbourne, I’ve seen how often people underestimate the expertise required to turn ideas—whether rough sketches or magazine clippings—into accurate, council-approved plans.

Drafting house plans in Australia isn’t a one-size-fits-all service. Costs vary depending on who you hire, the complexity of the design, and local council requirements, with fees typically ranging from $1,200 to over $10,000. Well-drafted plans form the backbone of a successful build, helping avoid costly changes and keeping builders, surveyors, and trades aligned.

In this guide, we’ll explain what influences drafting fees, how much you can expect to pay, and how to budget wisely—so you can move into the design stage with clarity and confidence.

What Influences House Plan Drafting Costs

When people ask, “How much does it cost to draft house plans?” I always say—it depends on how much thinking you want your plans to do for you. A good set of plans should answer every question a builder might ask on-site. The more precise and detailed they are, the smoother the project runs. That’s where cost differences start to appear.

Over the years, I’ve seen two near-identical builds vary by thousands simply because one client’s site was dead flat and the other sat on a tricky incline in Bentleigh East. That slope alone required extra structural detailing, drainage drawings, and coordination with an engineer. Below are the main factors that affect your drafting budget in Victoria.

Size, Design Complexity, And Site Conditions

The larger or more intricate the home, the more hours your draftsperson will spend bringing it to life. A simple single-storey brick veneer might take around 25–40 drafting hours, while a multi-level townhouse could stretch to 70 hours or more. Sloping blocks, awkward access, or bushfire-prone (BAL-rated) areas all add layers of complexity that demand extra documentation.

For example, a client of ours in Brighton wanted a split-level home to capture bay views. The design had to work with a three-metre fall from front to rear. The additional retaining walls, stepped slabs, and energy compliance reports added roughly $2,000 to the drafting stage alone. It’s the kind of thing that’s best addressed early—before a builder prices the job.

What affects drafting complexity:

1. Block slope or uneven terrain
2. BAL (Bushfire Attack Level) ratings
3. Flood or heritage overlays
4. Council setback, height, and shadowing rules
5. Unique materials or non-standard construction methods

Professional Type – Architect Vs. Draftsperson

Another significant influence is who prepares your drawings. Both architects and drafters can produce permit-ready plans, but their roles and pricing differ.

A registered draftsperson under the Victorian Building Authority (VBA) focuses on the technical side—turning concepts into precise CAD drawings ready for council submission. Expect to pay $80–$150 per hour, or a flat fee between $1,200 and $4,000 for most residential jobs.

An architect, on the other hand, combines creative design with project coordination and compliance management. They’ll often charge 7–12% of construction cost or $150–$300 per hour. Their services are ideal for homes that push design boundaries or require detailed spatial planning.

A few years back, we built a dual occupancy in Bentleigh East. The owners began with an architect for the concept stage, then switched to our in-house drafting team for working drawings. That move saved them around 30% on design fees, yet still delivered fully compliant documentation.

Professional	Typical Rate	Ideal For
Draftsperson	$80–$150/hr	New builds, extensions, permit drawings
Building Designer	$100–$200/hr	Concept design, layout, energy efficiency
Architect	$150–$300/hr or 7–12% of build cost	High-end or complex homes

Level Of Detail And Customisation

The amount of detail you want in your plans directly affects price. A pre-drawn or stock plan may only cost $800–$1,500, while a custom design that accounts for site orientation, energy ratings, and finishes can reach $10,000 or more.

In Melbourne, many councils—like Kingston or Glen Eira—require detailed drawings for planning applications, including elevations, shadow diagrams, and permeability schedules. These additions take time and skill but ensure smoother approval.

A good rule of thumb:

• Concept plans: Cheaper, but often insufficient for permits or builders.
• Construction-ready plans: More expensive upfront, but save headaches later.

I often tell clients, “You can pay for precision now or corrections later.” And trust me—corrections during construction cost far more.

Average Drafting Costs In Australia (2025)

By 2025, drafting prices across Australia have settled into a fairly predictable pattern — though Melbourne, as always, sits toward the upper end due to its tighter planning regulations and higher demand for dual occupancies and custom homes. Whether you’re planning a minor renovation or a complete knockdown rebuild, understanding how different billing methods work will help you compare quotes with confidence.

From my own experience, most clients underestimate just how much time is involved in documentation. A standard three-bedroom home might seem straightforward, but once you factor in site analysis, energy reports, and council revisions, your draftsperson can easily clock 40–60 hours on the job.

Typical Fee Structures

Here’s what you can expect when comparing how drafters charge in Melbourne and broader Victoria:

Billing Method	Average Cost (AUD)	Details
Hourly Rate	$80 – $150/hr	Best suited for renovations or smaller projects. Most local drafters charge by the hour when design changes are uncertain.
Per Square Metre	$5 – $55/m²	More common for new homes or developments. Simpler builds, such as brick veneers, sit at the lower end; complex designs, such as multi-unit projects, cost more.
Fixed Project Fee	$1,200 – $4,500	Usually covers the complete drawing set for a single home. Ideal for explicit, well-defined scopes.
CAD Conversion / Redraws	$50 – $200 per sheet	Used for turning hand sketches or old plans into digital CAD format for updates or extensions.

In Melbourne’s inner suburbs, fixed-price agreements are increasingly popular. Builders prefer them because they lock in drafting costs early, especially when paired with design-and-construct contracts.

Drafting Costs By Project Type

Project Type	Typical Cost Range (AUD)	Notes
Pre-drawn or stock house plans	$800 – $1,500	Suits basic single-storey designs; still requires local compliance adjustments.
Custom home design	$2,500 – $10,000+	Based on design complexity and inclusion of 3D visuals or energy assessments.
Dual occupancy/townhouse	$4,000 – $12,000	Includes site analysis, planning drawings, and coordination with council.
Renovation or extension plans	$1,000 – $4,000	Dependent on the existing structure accuracy and required site measurements.
As-built or existing condition plans	$700 – $1,500	Required when renovating older homes or submitting retrospective permits.

I recently worked with a family in Oakleigh who wanted to add a rear extension to their post-war weatherboard. Their total drafting fee came to $2,200, which included new floor plans, elevations, and a simple site plan for their council application. Compare that to a dual occupancy we did in Bentleigh East — two modern townhouses with 3D modelling and energy rating reports — where the documentation came in closer to $6,500. Same suburb, very different scope.

Drafting Hours And Typical Timelines

Project Size	Estimated Drafting Hours	Average Turnaround
Small renovation	20 – 35 hrs	2–4 weeks
New single-storey home	40 – 60 hrs	4–8 weeks
Dual occupancy	70 – 100 hrs	6–10 weeks
Complex custom design	100+ hrs	8–12 weeks

Keep in mind that councils like Glen Eira or Kingston can take 4–6 weeks just to review planning applications. So even if your drawings are ready, allow room for back-and-forth requests. The trick is to have a draftsperson familiar with your local council — it often means fewer revisions and less stress.

Hidden And Additional Drafting Costs

Every builder and designer will tell you — the drawings are just one piece of the puzzle. The actual cost of preparing house plans often extends beyond your draftsperson’s invoice. There are engineering reports, surveys, council fees, and permit applications that can quickly add up if you’re not prepared. I’ve seen homeowners in Melbourne caught off guard by these extras, especially those tackling their first build.

One couple in Glen Huntly, for example, thought their $2,500 drafting quote covered everything. When it came time to submit to the council, they were hit with another $3,000 in supporting documentation costs. It’s not that their draftsperson overcharged — they simply hadn’t been told about the hidden steps. To avoid that kind of surprise, here’s a breakdown of what to budget for.

Engineering, Survey, And Permit Fees

These are some of the most common additions to your drafting budget:

Service	Typical Cost (AUD)	Purpose
Structural Engineering Certification	$600 – $2,500	Certifies beams, footings, and load-bearing elements. Required for all new builds and most major extensions.
Land / Feature Survey	$400 – $1,800	Provides accurate site levels, boundary dimensions, and existing structures for the base plan.
Soil Test (Geotechnical Report)	$300 – $800	Determines footing system requirements to comply with NCC standards.
Energy Report (6–7 Star)	$250 – $600	Mandatory under the National Construction Code (NCC) for all new dwellings.
Council Application Fees	$900 – $3,000	Covers town planning, advertising, and resubmission charges.
Building Permit	$1,000 – $2,500	Required before construction begins; fee depends on project value and size.

Even if your draftsperson provides coordination services, these fees are usually paid directly to each consultant. In Melbourne, every local council sets its own rates, so always check the planning department’s website for up-to-date figures.

I like to tell clients to think of this phase as the “compliance package.” It’s the layer of documentation that proves your design is safe, efficient, and lawful. Skipping or delaying any of it can stall your permit approval — or worse, force redesigns later in the process.

Plan Revisions And Redesign Fees

Few designs stay exactly as they begin. Changes are part of the journey — but they do cost time and money.

Type of Change	Estimated Cost (AUD)	Example
Minor Edits	$150 – $700	Moving doors, resizing windows, or adjusting internal walls.
Major Layout Changes	$2,000 – $3,000	Altering floor area, rooflines, or structural framing.
Council Redesigns	$500 – $1,500	Adjustments to satisfy council planning requests.
Rush Services	+15% – 25% surcharge	Fast-tracking drawings for tight permit deadlines.

I’ve learned over time that clients who lock in their design decisions early often save the most. One project in McKinnon springs to mind: the homeowners changed their kitchen layout three times after structural drawings were finished. Each revision triggered engineering updates, costing nearly $1,200 extra. Clear communication and early planning would have avoided the double-handling.

Blueprint Printing And Reproduction Costs

While much of today’s documentation is digital, some councils and builders still request physical plan sets. Printing costs can vary depending on paper type and size.

Material	Cost per Sheet (AUD)	Use Case
20–24 lb standard paper	$0.10 – $10.00	For client and council copies.
Waterproof / Tyvek paper	$2.50 – $40.00	For outdoor use or construction site durability.

These costs are small individually but can accumulate over multiple revisions. Most of our clients now prefer PDF plans, which are accepted by almost every Melbourne council and are easier to share with consultants.

Ways To Save On House Plan Drafting Fees

After three decades in construction, I’ve learnt that saving money doesn’t mean cutting corners — it means planning smart. In Melbourne, homeowners often assume the only way to reduce drafting costs is to find the cheapest quote. The truth is, the cheapest quote can end up costing the most if it lacks the detail required for council or builders. Instead, the goal should be value, not just a low fee.

Here are tried-and-true strategies that my clients use to keep costs under control without compromising quality or compliance.

Use Pre-Approved Or Modified Designs

Starting with a pre-drawn or previously approved design can save thousands in drafting and design time. Many Victorian councils publish examples of compliant house layouts or subdivision footprints that already meet setback and coverage rules. By customising these, you skip the trial-and-error phase that comes with fully bespoke designs.

For example, a client in Cheltenham purchased an off-the-shelf four-bedroom floor plan for $1,200. Our drafting team modified it to suit a narrower block, adjusted the setbacks for Kingston Council, and prepared the final plans for $1,800 more. That’s $3,000 total, compared to over $8,000 for a brand-new custom design.

Option	Typical Saving (AUD)	Best For
Modify existing pre-drawn plan	$2,000 – $5,000	New builds or subdivisions
Reuse previous project documentation	$1,500 – $3,000	Developers or repeat builders
Adjust a builder’s base design	$1,000 – $2,500	First-home builders on a budget

Keep in mind: modifications still need to be signed off by a VBA-registered draftsperson to ensure compliance with the National Construction Code (NCC).

Combine Design And Drafting Under One Builder

One of the most effective cost-saving methods is to engage a design-and-build company that manages both the creative and technical sides in-house. Builders like us can package design, drafting, and permit coordination into a single workflow.

This often means fewer consultants, less back-and-forth, and lower cumulative costs. In most Melbourne cases, clients who take this path save 10–20% compared to hiring separate design and drafting professionals.

We recently worked with a Bentleigh East couple on a dual occupancy project. Instead of outsourcing drafting to an architect, they opted for our integrated design-build service. Not only did they save around $4,500, but their approvals were finalised four weeks faster — simply because all documentation was produced under one roof.

Invest In Early Site Planning

It might sound dull, but early site research is one of the smartest investments you can make. Before you brief your draftsperson, gather as much information as possible about your land.

This includes:

1. Title plan showing boundaries and easements.
2. Soil test for footing requirements.
3. Land survey with accurate levels.
4. Council overlays (heritage, flood, vegetation, or bushfire).
5. Neighbourhood character statements for planning compliance.

Having this data upfront reduces design revisions and gives your draftsperson a head start. In my experience, clear site documentation can shave 10–15 drafting hours off a project, which might translate to $1,000–$2,000 in savings.

DIY Planning Tools

For homeowners wanting to visualise their ideas before hiring a professional, there’s a growing range of user-friendly software options. Tools like SketchUp, Chief Architect, or RoomSketcher let you experiment with layouts, furniture placement, and façade styles.

These programs won’t produce code-compliant blueprints — only a registered draftsperson can do that — but they’re great for communicating your vision. When a client hands me a 3D mock-up of their ideas, it often cuts down multiple rounds of revisions.

Software	Cost (AUD)	Use Case
SketchUp (Pro)	$450 – $600/year	3D concept models
RoomSketcher	Free – $150/year	Quick layout planning
Chief Architect Home Designer	$700 – $1,200 one-time	Advanced residential visualisation

A word of advice: treat DIY tools as a sketchpad, not a substitute for professional work. You’ll still need a VBA-registered practitioner to prepare permit-ready plans that meet the Building Regulations 2018 (Vic).

Local Tip: Avoid Overdesigning

Melbourne’s building scene loves innovation, but there’s a fine line between creative and costly. Features like curved walls, non-standard window sizes, or cantilevered decks look striking — yet each one can add hours of documentation and engineering.

I recall a townhouse in Caulfield where the client requested angled feature walls to create visual interest. Beautiful idea, but the extra geometry added $1,800 in drafting time and an extra week of engineering coordination. In the end, the walls were simplified — same street appeal, lower cost.

If you’re building to a strict budget, simplicity is your best friend. Straight lines, standard dimensions, and efficient floor plans keep drafting fees manageable while still delivering a stunning result.

Real-World Examples From Melbourne Projects

Over the years, I’ve found that real figures tell the story better than theory ever could. Melbourne’s property scene is as varied as its weather—what you’ll pay to draft a new home in Bentleigh East will differ from a townhouse in Brighton or a heritage extension in Glen Eira. The following examples show how drafting costs change based on project type, complexity, and council requirements. These are real numbers from recent projects handled by our team or comparable firms across Melbourne.

Single-Storey Home – Glen Eira

A young couple approached us to draft plans for their first family home in Glen Eira. They wanted a three-bedroom, two-bathroom single-storey build—nothing extravagant, but with an open-plan living area that made good use of natural light.

Project Snapshot:

• Size: 180 m²
• Services: Drafting, energy report, structural coordination, and building permit documentation
• Council: Glen Eira
• Timeline: 6 weeks
• Total Drafting Cost: $3,200

This project was straightforward. The block was level, the overlays were minimal, and the design was practical. The most time-consuming part wasn’t the drawing—it was the minor tweaks for the energy report. By aligning windows and shading correctly, we achieved a 7-star energy rating without any major redesigns. The clients were thrilled, and their builder later told me those detailed plans saved at least a week on-site.

Dual Occupancy – Bentleigh East

Dual occupancies are a Melbourne specialty. Land values in the inner south-east make it a smart move for families wanting to maximise return on their block. One of our recent Bentleigh East projects involved replacing an older home with two contemporary side-by-side townhouses.

Project Snapshot:

• Size: Combined 280 m² (140 m² each dwelling)
• Services: Concept development, full working drawings, energy compliance, planning submission support
• Council: City of Glen Eira
• Timeline: 10 weeks (including revisions)
• Total Drafting Cost: $6,800

The block had a tricky, narrow frontage, so fitting two driveways and garages required careful coordination. We also had to meet private open space and overshadowing limits under Clause 55 of the Victorian Planning Provisions. That meant extra shadow diagrams and permeability calculations.

In this case, our familiarity with Glen Eira’s planning team made all the difference. Because we pre-empted likely concerns and included key compliance notes on the first submission, the plans passed planning without needing a redesign—a rare win for a dual occupancy. The clients later told me they budgeted $10,000 for plans, so they were more than happy with the result.

Major Renovation – Brighton

A Brighton couple contacted us about adding a rear extension and internal remodel to their 1950s weatherboard. The brief was to modernise the living area, add a master suite, and maintain the home’s coastal charm. Renovations like this can be unpredictable—existing structures rarely match old plans, and many older homes reveal surprises once measured.

Project Snapshot:

• Size: 100 m² addition
• Services: Measured drawings, new floor plan design, elevations, coordination with the engineer, energy rating report
• Council: Bayside
• Timeline: 8 weeks
• Total Drafting Cost: $4,500

Because the original plans were long lost, we first produced as-built drawings. That step alone took several site visits and about 15 hours of measurement work. The extension itself was simple, but tying new and existing sections together required close coordination with the structural engineer. Despite the added complexity, the clients’ total documentation cost came in under budget, and their planning approval was cleared in just over five weeks.

Multi-Unit Development – Carnegie

For developers, drafting is an investment rather than an expense. We recently worked on a small three-unit project in Carnegie. The goal was to create efficient, market-ready plans that balanced design appeal with constructability.

Project Snapshot:

• Size: 3 x 2-bedroom townhouses, total 420 m²
• Services: Site analysis, complete drafting package, 3D presentation renders, and coordination with the civil engineer.
• Council: Glen Eira
• Timeline: 12 weeks
• Total Drafting Cost: $9,800

What drove the price up wasn’t the number of units but the documentation depth. The developer wanted detailed renders and presentation plans for marketing, which added roughly $1,200 to the total. In return, those visuals helped pre-sell two units before the build even began.

I often say to developers: “Good plans don’t just get you a permit—they help sell the project.” This job proved it.

Drafting your house plans is one of the smartest investments you can make before a single shovel hits the ground. In Melbourne, where local regulations, narrow blocks, and energy standards can add layers of complexity, having clear, accurate plans saves time, money, and stress. Whether you’re working with a registered draftsperson or an architect, choose someone who understands your suburb’s planning rules and communicates openly throughout the process.

From my experience, clients who invest in thorough documentation rarely face budget blowouts or costly redesigns during construction. Solid drawings mean fewer site errors, faster approvals, and smoother coordination between trades. At MJS Construction Group, we often remind homeowners that a good set of plans doesn’t just draw your home; it builds the confidence behind every decision that follows.
