Home Renovation Checklist: A Guide to Renovating Your House
Step 1: Understand Why You Are Renovating
Before thinking about finishes, floor plans or how large an extension should be, start with a much simpler question:
Why are you renovating?
Perhaps your existing home is too dark. The kitchen may be disconnected from the backyard. Your family might have outgrown the original floor plan, or years of previous alterations may have left the house feeling disjointed.
Try to identify the problems before deciding on the solutions.
Consider:
How does your current home work well?
Which spaces frustrate you?
Where do you naturally spend most of your time?
Do you need additional floor area, or could the existing house simply work harder?
How important are natural light, garden connections and outdoor living?
Are there original features you would like to retain?
How might your needs change over the next 10 or 20 years?
These conversations form the beginnings of your architectural brief.
The goal at this stage isn't to design the house yourself. It is to understand what you would like your renovation to achieve.
Step 2: Establish a Realistic Renovation Budget
Budget should be part of the design conversation from the beginning.
Before starting design work, establish a realistic construction budget and consider what sits outside that figure.
Depending on the project, your overall expenditure may also need to account for:
Architectural fees
Land surveying
Structural and civil engineering
Energy assessments
Building surveying
Planning consultants or specialist reports
Council and authority fees
Landscaping
Interior fixtures, fittings and appliances
Temporary accommodation
Contingencies for unforeseen work
Renovations can be particularly difficult to predict because existing buildings inevitably contain unknowns.
Opening an existing wall, floor or roof can reveal conditions that were impossible to see during the design process.
A sensible contingency and an honest conversation about budget are therefore important from the outset.
Step 3: Decide What Is Worth Keeping
One of the biggest differences between designing a new home and renovating an existing one is that a renovation already has a story.
We don't necessarily see the existing building as something that needs to be erased.
Instead, we ask:
What is good here?
An original weatherboard façade might contribute strongly to the street. Existing bedrooms may be perfectly functional. A masonry wall might have beautiful texture. An established tree could become the focal point of a new living space.
Retaining existing building fabric can also reduce unnecessary construction and allow the budget to be directed toward the areas that genuinely need improvement.
Sometimes the most successful renovation is not the largest intervention — it is the most considered one.
Step 4: Develop Your Architectural Brief
Your brief should combine practical requirements with how you actually want to live.
Of course, we need to know whether you require three bedrooms or four, one living area or two, a home office, ensuite, garage or larger kitchen.
But we also want to understand the less measurable things.
Do you entertain twenty people at Christmas?
Does everyone congregate around the kitchen bench?
Do you want somewhere quiet to read in the afternoon?
Does the dog need direct access to the backyard?
Do you love bright, open spaces, or smaller and more intimate rooms?
A good architectural brief becomes a conversation about everyday life rather than simply a list of rooms.
It is also useful to identify your non-negotiables and negotiables. Knowing where you see the greatest value helps us make informed decisions when balancing design, existing conditions and budget.
Step 5: Explore the Concept Design
This is where the renovation begins to take shape.
Rather than immediately settling on one solution, we generally explore the opportunities presented by the site, existing building and client brief.
For a renovation, this might mean investigating questions such as:
Do we extend out or up?
Could removing one poorly positioned room transform the rest of the house?
Can a courtyard introduce light into the centre of a narrow site?
Should the new architecture contrast with the existing house or quietly continue it?
Can we achieve the brief without dramatically increasing the floor area?
At Ashley O’Neill Architects, our projects are not developed around a predetermined architectural style.
Instead, the design grows from the conditions of the site, the existing building and the people who will live there.
Through discussion and iteration, these early ideas are refined into a preferred architectural direction.
Step 6: Develop the Architecture
Once the overall arrangement feels right, we begin resolving the building in greater detail.
This is where plans become spaces.
We consider the relationship between floor plan, volume, material, structure, natural light and views.
Windows are positioned deliberately. Ceiling heights are considered. Connections between old and new are refined. Exterior materials begin to establish the architectural character of the renovation.
For our studio, this stage typically combines architectural drawings with 3D visualisation so that clients can understand the building spatially rather than needing to interpret technical drawings alone.
Material selections also begin to develop.
We generally favour a restrained approach — carefully selecting materials for their texture, longevity, context and contribution to the overall architectural idea rather than simply following current trends.
Step 7: Navigate Planning and Building Approvals
Not every renovation requires a planning permit, but many do.
Heritage overlays, neighbourhood character requirements, building height, overlooking, site coverage and other planning controls can all influence what is possible.
Where planning approval is required, your architect can coordinate the process, prepare the architectural documentation and respond to council requirements.
Following planning, the project will also need to satisfy building regulations before construction.
These are different approval processes, and understanding the pathway early helps avoid unnecessary surprises later.
Step 8: Prepare Detailed Construction Documentation
Once the design has been resolved, the project needs to be translated into information that can actually be built.
Construction documentation typically includes detailed:
Floor plans
Elevations
Building sections
Construction details
Window and door information
Interior elevations
Joinery documentation
Material schedules
Fixtures and finishes
Specifications
During this stage, we also coordinate the work of structural engineers, energy assessors, building surveyors and other consultants required for the project.
This is an important part of our architectural process.
Rather than leaving clients to coordinate multiple technical conversations themselves, we aim to act as the central point of contact — bringing the different disciplines together around a clearly resolved architectural outcome.
Step 9: Select the Right Builder
The cheapest builder is not automatically the right builder.
A successful renovation relies heavily on the relationship between client, architect and builder.
Experience with similar projects, communication style, attention to detail, availability and an understanding of the architectural intent can all be just as important as the final tender price.
Through a tender process, builders can price a coordinated set of architectural and consultant documents.
We can then assist clients in comparing submissions, understanding exclusions or differences between prices and selecting a builder appropriate for the project.
How Long Does a Home Renovation Take?
One of the most common questions we receive is: when can we start building?
For a considered architectural renovation, there can be a substantial amount of work before construction begins.
Site investigation, briefing, concept design, design development, planning approvals, consultant coordination, construction documentation, tendering and building approvals all occur before a builder arrives on site.
For many projects, allowing approximately 9–12 months of pre-construction work is a useful starting expectation, although every renovation is different.
Complex planning approvals, heritage requirements or larger projects can extend this timeframe.
Starting the architectural process early gives the project the breathing room it needs to be properly considered.
Renovating Doesn't Always Mean Building More
There is a tendency to measure renovations in square metres.
We think there is a better measure: how much better does the house work?
Some existing homes already contain enough floor area. What they lack is clarity.
Improving orientation, opening a living area toward the garden, introducing daylight, removing an awkward addition or reorganising circulation can sometimes transform a house without dramatically increasing its footprint.
Our approach to renovation is therefore less about simply adding space and more about understanding how architecture can improve the space you already have.
It means respecting what deserves to remain, removing what doesn't work, and introducing new architecture with purpose.
Considering a Home Renovation?
Ashley O’Neill Architects works across Geelong, Melbourne and regional Victoria, with a focus on carefully considered residential renovations, extensions and new homes.
Our process is collaborative and architect-led, guiding projects from the first conversations and site investigations through concept design, approvals, detailed documentation, builder selection and construction.
If you're considering renovating an existing home, we'd love to hear about the house, what isn't working — and what you imagine it could become.
