Renovation ROI – Which Upgrades Add the Most Value Locally

Renovating can be one of the most effective ways to increase a property's value — but only when the upgrades align with local buyer expectations. In coastal markets like the Illawarra, not all renovations deliver the same return, and overcapitalising is a real risk.
Buyers here value lifestyle, functionality and low-maintenance living. The most successful renovations enhance how a home feels to live in, rather than simply adding cost or complexity. Understanding what local buyers respond to — suburb by suburb — is the key to achieving strong renovation ROI.
This article breaks down which upgrades consistently add value in the Illawarra, which ones often disappoint, and how to renovate with a clear strategy rather than guesswork.

1. Kitchens, Bathrooms and Layout – Where ROI Starts
Across almost every Illawarra suburb, kitchens and bathrooms remain the most influential areas for renovation. They shape first impressions, emotional connection and perceived value.
Kitchens: Functional, Light and Coastal-Neutral
In coastal markets, buyers aren't looking for showpiece kitchens — they want practical, bright spaces that feel easy to live in.
Upgrades that perform well locally include:
stone or durable composite benchtops
quality cabinetry in neutral tones
modern but understated splashbacks
good storage and pantry space
improved lighting (especially natural light)
In suburbs like Woonona, Bulli and Corrimal, updated kitchens can significantly reduce days on Market and support stronger competition. In older housing stock, even modest kitchen updates often deliver solid ROI.
Overcapitalising with luxury appliances or bespoke finishes rarely improves returns — buyers value clean, functional and cohesive over premium branding.
Bathrooms: Clean, Coastal and Low-Maintenance
Buyers closely scrutinise bathrooms. Renovations that work best locally focus on simplicity and durability.
High-performing upgrades include:
walk-in showers
large-format tiles
floating vanities
neutral colour palettes
good ventilation
In coastal areas, buyers are susceptible to moisture, mould, and maintenance requirements. Well-finished bathrooms signal that a home has been cared for — and reduce perceived future costs.
Suburbs with older homes, such as Dapto, Berkeley and Port Kembla, often see strong ROI from bathroom upgrades that modernise without overspending.
Improving Layout Without Major Extensions
Reconfiguring space can deliver excellent ROI when done strategically.
Common value-add changes include:
opening kitchens to living areas
improving flow between indoor and outdoor spaces
creating defined dining areas
improving bedroom proportions
These changes often outperform large-scale extensions in terms of cost-to-value uplift, particularly for family buyers.

2. Coastal-Specific Upgrades That Buyers Value
The Illawarra's coastal environment shapes buyer priorities. Renovations that account for climate, lifestyle, and maintenance realities tend to outperform generic upgrades.
Indoor–Outdoor Living
Coastal buyers strongly value a connection to outdoor space.
High-ROI upgrades include:
covered alfresco areas
decks or patios with coastal finishes
large sliding or bifold doors
Level Access to yards
In suburbs like Thirroul, Austinmer and Kiama, even modest outdoor improvements can materially increase appeal — particularly for family and downsizer buyers.
Low-Maintenance Landscaping
Buyers consistently respond to homes that look established but easy to maintain.
Effective landscaping upgrades include:
simple lawn areas
coastal plants suited to salt air
defined garden edges
improved drainage
privacy screening
Highly manicured gardens may look impressive, butdon'tt always add proportional value.
Practical, low-maintenance outdoor spaces perform better over the long term.
Materials That Withstand Coastal Conditions
Illawarra buyers are increasingly aware of coastal wear and tear.
Upgrades that signal durability include:
aluminium or treated timber joinery
corrosion-resistant fixtures
quality roofing and gutters
updated windows and doors
In seaside pockets, these upgrades may not always add headline value — but they significantly reduce buyer objections and negotiation pressure.
Energy Efficiency and Comfort
While rarely the headline feature, comfort upgrades support buyer confidence.
Strong performers include:
insulation
ceiling fans
efficient heating/cooling
double glazing in exposed locations
These improvements are desirable to families and downsizers planning to stay long-term.
3. Renovations That Often Disappoint on ROI
Not all renovations add value — and some actively erode ROI when they exceed local expectations.
Overcapitalised Luxury Finishes
High-end finishes rarely deliver proportional returns in most Illawarra suburbs.
Examples include:
luxury imported fixtures
custom joinery beyond buyer expectations
niche design features
ultra-premium appliances
Buyers appreciate quality—but not at the expense of affordability or cohesion with the suburb.
Large Extensions Without Market Alignment
BiSignificantxtensions can be risky if they push the property well above local price ceilings.
Before extending, it's critical to ask:
Does the suburb support this price point?
Will the added space match buyer demand?
Does the likely resale value justify the cost?
In many cases, targeted internal upgrades outperform significant additions.
Highly Personalised Design Choices
Renovations that reflect personal taste too strongly can limit buyer appeal.
Bold colours, unusual layouts or niche materials often reduce competition — and competition drives price growth.
Neutral, adaptable spaces consistently perform best.
Local Insight: Renovating With Illawarra Buyers in Mind
Across the Illawarra, the most substantial renovation ROI comes from:
improving livability
modernising tired spaces
enhancing natural light
creating indoor–outdoor flow
reducing perceived maintenance
Renovations that align with coastal lifestyle expectations consistently outperform trend-driven upgrades.
Should You Renovate — or Buy Renovated?
This is one of the most common questions buyers face.
Renovating can deliver substantial value when:
The purchase price reflects the property's condition
Renovation costs are controlled
upgrades align with buyer demand
Timelines and disruption are manageable
Buying renovated often suits buyers prioritising certainty and lifestyle — but comes at a premium.
Understanding this trade-off is key to making the right decision.
