New homes
For a new residence, the process begins with the land itself: the site survey, planning controls, orientation, building form and the way you want to live.

RESIDENTIAL / SELECTED WORK01 / THE IDEA
Every home starts with a different set of needs. Some begin with an empty block and a new brief. Others begin with a house that no longer suits the way its owners live. The process starts by understanding the site, the opportunities and what needs to change.
02 / THE PORTFOLIO
Two ways to explore the work: completed homes and residential projects still being developed.
COMPLETED PROJECTS
Completed residential projects, with photography and design imagery where available.
WORK IN PROGRESS
Current residential projects, explored through architectural design, sketches and visualisations.
Workshop note: Four project status corrections have been confirmed. Other working titles, images and descriptions remain subject to review before publication.
03 / TRANSFORMATION
Alterations and additions can reshape how a home looks, functions and connects to its surroundings.

The same clear design process, adapted to two quite different types of project.

For a new residence, the process begins with the land itself: the site survey, planning controls, orientation, building form and the way you want to live.
Explore new-home services
For an existing home, the design starts by understanding the original building, what can be retained and how new spaces might improve everyday living.
Explore alterations & additionsA CLEAR DISTINCTION
A site-led design: establish what is possible on the land and develop the building from the ground up.
An investigation-led design: establish how the current building works and how it can be changed.
From initial site assessment to architectural design, documentation and the appropriate approval pathway.
We start with your brief and a review of the property, planning controls and site opportunities. The design is then developed through three sketch-plan steps:
The standard new-home design scope provides an initial meeting, up to two further meetings and up to two design revisions.
During design, the material normally includes a site plan, dimensioned floor plans, elevations, sections where needed and 3D visualisations. The later working-drawing stage develops the architectural documents for approvals, general builder pricing and residential construction.
Depending on requirements, these can include roof and area plans, window and door schedules, energy-rating and bushfire notes, shadow diagrams and other supporting plans.
A current survey prepared by a registered surveyor is normally needed. For new homes, the standard agreement requests this in DWG/CAD format, showing site boundaries, levels, existing structures, services and significant site features. Preliminary discussions can happen before the survey, but proper design documentation may need to wait until it is available.
The standard new-home agreement allows approximately three to six months for the design stage. This depends on the site, decisions, consultant information and any indicative builder feedback. Later documentation and statutory approval periods are separate and depend on the project.
We examine the likely ACT approval pathway for the design. Where eligible, a development-approval-exempt approach may be considered; other sites may require an Exemption Declaration or full Development Application. Building Approval is a separate requirement. Statutory submissions and specialist reports are additional services or can be arranged through your chosen certifier or consultants.
Rural or complex sites may also require bushfire, geotechnical, wastewater, stormwater, ecological or other specialist advice. Residential energy ratings can be undertaken by the practice or by a separate qualified assessor. Read about residential energy ratings.
Renovations, extensions and alterations shaped by the original home, your current needs and the property’s constraints.
The first step is to understand the existing house and the changes you want to make. We review the original plans and current site survey, consider planning constraints and explore design options before choosing a preferred direction.
The design then develops through preliminary, revised and final sketch plans, with floor plans, elevations, sections and black-and-white 3D form studies to help communicate the proposal.
As well as the ordinary architectural drawings, an alteration project may require demolition plans, building-envelope information, shadow studies, protection of existing landscape, waterproofing and accessibility details, and erosion-control documentation. The extent depends on the design and approval pathway.
The standard alteration agreement asks for the original residence drawings and a current site survey. When original plans are missing, extra work may be needed to establish the existing conditions before design can proceed reliably.
For typical alterations and additions, the standard agreement allows about two to three months for design and documentation before an approval submission, depending on feedback, the existing building, design changes and other project requirements. Approval assessment periods are additional.
Yes, where agreed. Depending on the property, an eligible minor-approval pathway or a full Development Application may be needed. Additional clearances can also arise for trees, driveways or services. The client, builder or certifier may alternatively manage the applications.
The descriptions above are a public-facing explanation of the standard ACT services, not a substitute for a project-specific proposal. The scope of work is confirmed before engagement.
05 / THE PROCESS
A practical sequence, with each stage explained and agreed before work proceeds.
Discuss the way you want to live, review your site information and identify constraints that will shape the design.
Review floor plans, elevations and three-dimensional studies; provide feedback and resolve the preferred design.
Develop the architectural documentation and, where agreed, assist with the approval pathway and supporting material.
HOW WE WORK
Designs are presented in drawings and three dimensions so you can understand the proposal before progressing. The architectural work is staged, with services confirmed in an individual fee proposal. You can arrange your own builder and consultants, with the precise roles agreed for each project.
We do not assume every project needs the same approval route or the same supporting reports. These are assessed for the site and proposed work.

08 / PRACTICAL INFORMATION
Answers to the questions that most often come up when planning a residential project.
A current survey is normally required for design. A new-home survey should be supplied in DWG/CAD format. For alterations, original house plans are also important. We can discuss your project before all documents are ready.
Yes. The standard service arrangements suit clients who appoint their own builder or act as owner-builders. Builder selection, tendering, negotiation and construction-cost management are not included in the standard architectural scope.
Yes. Three-dimensional studies help explain the building's shape and design as ideas develop. New-home projects can include preliminary external material and colour visualisations. These are illustrative, rather than detailed interior-design or finishes-selection services.
That depends on your site and proposal. Some projects may qualify for an exempt pathway or minor declaration; others require a Development Application. Building Approval is considered separately. Eligibility and the most appropriate pathway are reviewed for each job.
Detailed interiors, kitchen and joinery design, fixture selections and finishes schedules are outside the standard architectural scope. If these are needed, they should be discussed and separately agreed before work proceeds.
Surveying, structural engineering and other specialist reports are normally arranged and paid for separately. Rural or constrained sites may need bushfire, wastewater, soil, stormwater or ecological advice. Where provided, information can be incorporated into the architectural documents within the agreed scope.
Construction supervision, inspections, certification and formal contract administration are not part of the standard service. Additional architectural input during construction can be discussed separately.
Yes, work is staged. A project-specific proposal sets out what is included, and a further stage proceeds once it is agreed. New-home services are expressly set up with written approval between stages.
Project scope, consultant requirements and any statutory pathway are confirmed individually. These general answers reflect the practice's standard 2026 ACT residential service agreements.

An energy rating should help you understand the home you are designing, and the choices that will make it work better.
ENERGY PERFORMANCE STARTS AT DESIGN STAGEPrimary Nominated Architect, Jefferson Godfrey Architects Pty Ltd.
ACT Architect Registration No. 1088
ACT construction occupations licence held by Jefferson Godfrey. Residential energy assessment services within the applicable licence scope.
Member of the House Energy Raters Association.

AN ARCHITECTURAL PERSPECTIVE
Insulation and glazing specifications matter, but the overall design matters too. Orientation, window proportions, shading, construction type and the way spaces are arranged can all affect the result. As an architect, I can help the project team consider those choices together, rather than treating the rating as a last-minute paperwork exercise.
The aim is to find a practical and proportionate response for the particular house, site and budget. The most expensive specification is not automatically the best solution.

Comfort begins long before construction.
THE SERVICE / 02
My focus is residential work. I prepare energy ratings for my own architectural designs and can consider assessment work prepared by others.
Thermal performance can be considered while the design is developing, with the rating and the architectural drawings informed by the same design decisions.
Residential energy assessments for homeowners, architects, building designers and builders, accepted on a case-by-case basis. I can work with your existing plans and team.
Plans-based energy assessment for new homes and suitable major alterations or additions. The required rating and approval pathway depend on the project and jurisdiction.
Available for ACT residential projects and selected projects elsewhere in Australia, subject to the applicable accreditation, licensing, compliance pathway and agreed scope. Existing-home sale and rental disclosure ratings are a separate assessment service and are not advertised here.
NatHERS thermal star rating for many new homes under NCC 2022.
UNDERSTANDING ENERGY PERFORMANCE
A NatHERS thermal star rating estimates how much heating and cooling a home's design is expected to need to maintain indoor comfort in its local climate. A higher rating generally indicates lower modelled heating and cooling demand.
Many new homes assessed through the NatHERS pathway now target at least seven stars. The precise requirement depends on the location, dwelling type and applicable approval pathway. In the ACT, the current new-home standard is equivalent to seven stars.
CLARITY / 03
Models heating and cooling demand from the building design and thermal envelope. This is the main residential rating service described on this page.
Looks at major fixed systems and appliances, and may consider onsite generation and storage. This is distinct from the thermal star rating and may form part of wider compliance requirements.
Different jurisdictions apply their own submission requirements. ACT building approval and NSW BASIX requirements should be confirmed for each project; a NatHERS star rating alone does not replace all approvals.
THE PROCESS / 04
For an external project, an assessment begins with the documentation already available. I will confirm what is needed and whether the project is within scope.
Provide the address, proposed drawings, window and construction information you have. Early design documents are fine for an initial review.
I check the available information and undertake the relevant residential thermal modelling once the details are sufficient.
If a design falls short, we can review practical adjustments to glazing, insulation, shading or building configuration where appropriate.
The agreed rating documentation and relevant assumptions are provided for the project team's approval process.
GETTING STARTED / 05
You do not need to have everything finalised before making contact. Send what you have and I can identify any gaps before an assessment begins.

PRACTICAL QUESTIONS / 06
Yes, on a case-by-case basis. I can review residential plans prepared by others and confirm whether I can undertake the assessment, what additional details are needed and how the advice will fit with your project team.
Yes. This is a key advantage of combining architecture and thermal assessment. I can help identify design and specification options that are worth testing, taking into account the implications for the overall project. The final result depends on the documented design and modelling.
No single rule applies to every home or approval. Seven stars is the general benchmark for many new homes using a NatHERS pathway under NCC 2022, including the ACT's current equivalent requirement. Alterations, existing dwellings, transitional approvals and state-specific pathways can have different requirements.
No. Send the plans and specifications currently available. I can check the stage of the project, advise what else is needed and confirm whether the rating can proceed.
The service described here centres on plans-based residential thermal assessment. Whole of Home calculations, BASIX certification and other sustainability submissions have separate requirements. I will confirm what is included in the agreed service before work begins.
This page focuses on residential design ratings for new homes and appropriate major alterations or additions. ACT sale and rental EER disclosure statements are a separate assessment system; please do not assume they are included.
No. NatHERS estimates heating and cooling needs based on the documented design and standardised assumptions. Real-world comfort and energy use also depend on construction quality, appliances, how a house is occupied and other factors.
