Architect Fees in Tasmania: What Design Services Cost for a New Home

Before you can build a custom home in Tasmania, someone has to design it. Whether you engage a registered architect or a building designer, the design service is a separate cost on top of your construction contract — and understanding what that costs, and how fees are structured, helps you plan your total budget accurately. This guide covers how architects and building designers charge in Tasmania, what you get at each fee level, and how the integrated design-build model changes the equation.

Architect vs Building Designer: The Short Version

In Tasmania, both registered architects and registered building designers can legally produce the drawings required for a building permit on a residential project. The key differences are credential depth, scope of service, and fee level. We cover the distinction in detail in our guide to building designers versus architects in Tasmania. For the purposes of this guide, the short version is:

• Registered architect — university-trained (minimum 5–6 years), registered with the Architects Registration Board of Tasmania (ARBT), full scope from concept through contract administration. Higher fee.
• Building designer — may hold a diploma or degree in building design, registered with the Building Designers Association of Australia or equivalent. Typically engaged for design and documentation only; construction administration is less common. Lower fee, often flat-rate.

For most residential projects in northern and north-west Tasmania, a skilled building designer delivers a strong outcome at a lower cost. Registered architects bring additional value on complex, heritage, or architecturally ambitious projects — and on projects where contract administration is particularly important.

How Architects Charge: Fee Structures

Architectural fees in Australia are typically structured as one of three models:

Percentage of Construction Cost

The most common model for a full-service architectural engagement. The architect charges a percentage of the final construction cost — typically 7–15% for a new residential project, with an industry average around 10–12% in 2026. On a $700,000 home, a 10% fee is $70,000; on a $1,000,000 home, a 12% fee is $120,000.

The percentage covers the full scope: concept design, design development, council documentation, construction documentation, tendering, and contract administration during construction. Not all clients need all phases — if you are engaging a builder under a design-and-construct or integrated model, the later construction administration phases may be less relevant or handled differently.

Flat Fee

A fixed fee agreed upfront for a defined scope of work. More common for smaller or more predictable projects, or when the client only wants specific phases (design and permit drawings, but not contract administration). The risk for the architect is greater — if the project takes longer than expected, the fee is the same — so flat fees typically include contingency built in.

Hourly Rate

Used for advisory work, feasibility studies, and variations to existing designs. Registered architects in Australia charge $150–$350 per hour in 2026, depending on seniority, location, and firm size. Building designers typically charge at the lower end of this range. Hourly billing is less common for a full residential project because it offers the client limited cost certainty.

What the Fee Covers: Phases of Service

A full-service architectural engagement covers several distinct phases. You don't always need all of them — understanding what each covers helps you scope the engagement correctly:

• Feasibility / pre-design — site analysis, planning scheme review, budget testing. Often charged hourly or as a separate fixed fee. Identifies constraints before design begins.
• Concept design — floor plan options, massing, orientation, relationship to the site. The creative core of the process. Usually 2–4 rounds of refinement.
• Design development — resolving the structural approach, materials, services, and detailing. The design is developed from concept into a buildable proposition.
• Council documentation — drawings and reports sufficient for a planning permit application, if one is required. (Many standard residential projects are permitted development and don't need a planning permit — only a building permit.)
• Construction documentation — the full set of working drawings and specifications used by the builder to price and build the home. This is what your building permit is issued against.
• Contract administration — the architect's role during construction: reviewing progress claims, issuing instructions, visiting site at key stages, and certifying practical completion. Adds cost but provides independent oversight of the builder.

If you are working with a custom builder who provides their own site management and quality oversight, you may choose to engage the designer only for the design and documentation phases, and rely on the builder for the construction phase. This is common in the integrated design-build model.

Integrated Design-Build: How the Davies Model Works

Davies Design & Construction works in an integrated model with Align Architecture. Rather than engaging a designer separately and then approaching builders for quotes, clients work with both the design and construction teams from the start — the builder is involved in the design process, providing cost feedback as the design develops, and the design is tested against a real budget throughout rather than after the fact.

This model changes the fee conversation. Design fees are transparent and agreed upfront as part of the overall project scope. The builder's early involvement means the design is costed as it develops — avoiding the common problem of a beautiful design that comes in well over budget when it reaches the tender stage. For clients in northern and north-west Tasmania, the integrated model reduces the gap between concept and construction cost certainty.

Factors That Increase Design Fees

Several factors push design fees toward the higher end of the range:

• Sloped sites — more complex structural design, retaining, drainage, and access detailing
• Coastal exposure — wind, salt, and corrosion requirements affect material selection and detailing throughout
• Heritage overlay — heritage impact assessments and additional council consultation add time and scope
• Bushfire-prone areas — BAL-rated construction adds complexity to cladding, windows, and external detailing specification
• High-end finishes — specifying premium joinery, stone, bespoke fixtures requires more detailed documentation
• Multiple rounds of design revision — client-driven changes to the design after concept sign-off add time

Frequently Asked Questions

Are architect fees on top of the construction cost?

Yes. The design fee is a separate cost from the building contract. When budgeting for a new home, your total project cost is: land purchase + design fees + building contract + site costs + landscaping, fencing, and fit-out items not included in the build contract. Design fees are typically 3–12% of the construction cost depending on the scope and whether you engage a building designer or a registered architect. See our Pricing Guide for a full breakdown of what goes into a new home budget.

Can I get a building permit without an architect?

Yes — in Tasmania, a building permit can be issued based on drawings prepared by a registered building designer (not just a registered architect). In Tasmania, a building permit is issued by the council as permit authority. A building surveyor — either council-employed or an independent, privately accredited surveyor — assesses the design against the National Construction Code and issues a Certificate of Likely Compliance (CLC). The council then issues the building permit on the strength of that CLC. A registered building designer (not just a registered architect) can prepare the drawings for the permit application. The building permit is separate from any planning permit that may be required. Most new residential builds in northern Tasmania are designed by building designers rather than registered architects. For more on the permit process, see our guide to building permits in Tasmania.

How much should I budget for design fees in total?

As a rule of thumb for a standard new home with a building designer in northern Tasmania, budget $15,000–$30,000 for design and documentation. If you engage a registered architect for full service, budget 8–12% of your expected construction cost. These are indicative figures — the best approach is to brief two or three designers or architects, compare their scope of service and proposed fees, and select on fit and value rather than price alone.

Does Davies charge for design separately?

Design fees through the Davies and Align Architecture model are agreed as part of the overall project scope. An initial feasibility conversation is provided at no cost — if a project proceeds to concept design, a design fee is agreed with Align Architecture at that stage. Get in touch through our enquiry page and we can walk you through how the process and fees work for your specific project.
