Planning a Home Renovation in 2027 | Muir Projects

Planning a major home renovation in Wollongong or the Illawarra? Getting your builder, architect and budget aligned from the beginning can help you avoid costly surprises and create a home that delivers on your vision.

A successful home renovation takes more than a great design. It requires careful planning, realistic budgeting and a clear understanding of how your ideas will translate into a finished home.

With construction costs, material availability and building requirements continuing to evolve, homeowners planning a renovation in 2027 need to think beyond the initial design. Decisions made early in the process can have a significant impact on the overall cost, construction timeline and quality of the finished result.

At Muir Projects, we believe the best renovations begin with collaboration. Bringing your builder and architect together early helps establish a practical approach to the project, balancing architectural vision with construction expertise and financial reality.

Bring Your Builder and Architect Together Early

Your architect and builder bring different but equally important perspectives to a renovation.

An architect focuses on the design, spatial planning, natural light, functionality and overall appearance of the home. An experienced builder brings practical construction knowledge, trade coordination, material selection and an understanding of how the design can be delivered on site.

When these perspectives come together early, potential issues can be identified before they become expensive problems.

Discussing these details during the design stage gives everyone the opportunity to explore solutions while changes are still relatively straightforward.

For homeowners, this creates a clearer picture of the project's likely cost, scope and construction requirements before making major financial commitments.

Understand What Your Renovation Will Actually

Cost

A realistic renovation budget should cover more than the visible building work.

Depending on the scope of your project, you may also need to allow for:

• Architectural design, engineering and other consultants.

• Council approvals, certification and relevant compliance requirements.

• Demolition, excavation and unexpected existing-site conditions.

• Structural alterations, waterproofing and building-envelope upgrades.

• Windows, doors, cladding, roofing and internal finishes.

• Temporary accommodation or other costs associated with living through a renovation.

• Landscaping, external works and final completion items.

• A contingency for unforeseen conditions and approved changes.

The exact allowances will depend on your property, the extent of the renovation and the information available during estimating.

An experienced builder can help separate confirmed costs from provisional allowances and items that still require investigation or selection. This distinction is important because an early estimate based on incomplete drawings is not the same as a detailed, well-defined construction price.

A clear budget should identify what is included, what is excluded and which decisions still need to be made.

Make Material Selections Before Construction Starts

Late design decisions are a common source of unnecessary pressure during a renovation.

Changing window specifications, altering external cladding, upgrading flooring or selecting custom joinery after work has commenced can affect pricing, procurement and the construction sequence.

Some products also require longer lead times or specialist installation. If these details are not considered early, delays can occur while the site waits for materials or revised documentation.

Where possible, finalise key selections before construction begins. Your builder can help coordinate specifications, confirm availability with suppliers and identify products that may affect the programme.

At Muir Projects, we believe careful preparation and attention to detail are essential to delivering a quality result. The objective is to make important decisions at the right time, rather than rushing them when construction is already underway.

Plan for Building Requirements in 2027

Building regulations and compliance requirements should form part of your planning process, particularly for substantial renovations and extensions.

In New South Wales, the NSW Government has announced that NCC 2025 is scheduled to be adopted on 1 May 2027, subject to the applicable state variations and transitional arrangements. The relevant requirements for your project will depend on its timing, scope and approval circumstances.

If you are planning work that may commence around this period, speak with your architect, builder and relevant certifier early to establish which requirements apply.

Addressing compliance during design development can help reduce the risk of late documentation changes, redesign or additional work.

Your project team should also consider structural engineering, waterproofing, energy efficiency and other applicable requirements as part of the overall design and construction strategy.

Allow Time for Proper Planning

If you are hoping to renovate in 2027, starting the planning process early can give you more time to work through design, approvals, engineering, selections and pricing.

The time required will vary considerably depending on the complexity of the project, the existing condition of the home and the relevant approval pathway.

Rather than rushing straight into construction, use the early stages to resolve as many unknowns as possible.

A well-prepared project should have a clearly defined scope, coordinated documentation, a realistic budget, an agreed approach to selections and a construction programme based on the actual requirements of the work.

No amount of planning can eliminate every unexpected issue, particularly when renovating an existing home. However, good preparation gives you a stronger foundation for making decisions and managing risks when they arise.
