The most effective ways to modernise a commercial property and add value are to reconfigure the space for current tenant demand, upgrade lighting, heating and plumbing, improve energy performance, refresh signage and the entrance, secure the parking area and meet accessibility standards. Upgrades that cut running costs and make the building easier to lease usually matter most to tenants and buyers.
Key Takeaways
- Start with what tenants in your area actually want: layout, parking, security and running costs usually outrank purely cosmetic changes.
- Energy performance is now measured and disclosed: in Australia, office space of 1,000 square metres or more needs a NABERS Energy rating when it is sold or leased, as of October 2026.
- Plumbing, lighting and heating systems age even in well-kept buildings; replacing them can lower running costs and reduce the risk of breakdowns.
- Major building work can trigger accessibility requirements, such as Australia’s Disability (Access to Premises — Buildings) Standards 2010.
- Plan upgrades in stages, get licensed trades and check council approvals before work starts.
Owning a commercial property is a significant long-term investment. But, with so many other property developers competing for the same space, you might find it necessary to upgrade your building to keep it relevant in your neighbourhood.
Property upgrades can include extensive internal and external changes. A building upgrade would also not be complete without consultation from one of the commercial plumbers Melbourne property owners commonly call on for this kind of work.
Give Your Property a New Lease on Life
Any commercial property can be a solid investment when it is well located and well managed. However, to sustain your investment you’ll have to keep your property well maintained. Although, a clean building isn’t always enough if it’s old and dated.
Fortunately, there are several cosmetic changes and structural additions that you can make to change your commercial property from drab to fab. Read on for eight practical ways to give a dated commercial property a new lease on life.
Redesign the Space
One of the biggest mistakes some property owners make is not realising that times change. Ever-changing times bring new demands and new trends. This applies to your commercial space as well. During your property’s lifetime, you might have to reconfigure the space to keep it relevant.
This means a space that was once a warehouse setting might now be more effective as an office block. Adding parking, where local planning rules allow it, can make the property more functional and more attractive to tenants, which in turn can support its value.
Update and Modernise
As times change it becomes important to update and modernise your building. Updating systems such as heating and lighting will also contribute toward improving energy-efficient standards.
Nothing says modern like adding current fixtures such as skylights and solar panels. In addition to modern light fittings, a few strategically placed skylights will make the building more appealing.
Upgrade and Replace Dated Plumbing
No matter how good the condition of your building is, at some point, the plumbing will need to be upgraded. As commercial plumbing companies in Melbourne and elsewhere will confirm, pipes and components wear out over time and eventually need replacing.
Depending on the age of your building, the plumbing system could be outdated. Many commercial plumbing companies can easily give you a quote to replace the outdated pipes and fixtures. They can also check key components such as the thermostatic valves.
Give the Property a Name
This might sound odd but giving your property a name makes it easier for people to identify with its location and purpose. Well-known examples include Trump Tower, the 58-storey mixed-use tower on Fifth Avenue in New York City completed in 1983, and Grosvenor Place, the 44-storey office tower at 225 George Street in Sydney completed in 1988.
Update the Signage
Old and dated signage will do nothing for your building’s image or your reputation as a property owner. If your building has any signage remaining from the previous tenant, you should remove it. Any generic signage should be clear, modern and easy to read.
If you’re going to name your property, it would be a good idea to add a sign with this name to your building. That way it’ll be easier for prospective tenants to easily identify your premises.
Modernise the Outside Area
The outside area of your building is the first impression anyone gets of your property. In real estate terms, it’s often referred to as “curb side appeal.” Any prospective tenants might decide against your building if their first impression is a negative one!
Clear away any overgrown plants and shrubbery. Ensure the area is free of any debris and rubble. It would also be a good investment to modernise the doors, windows and pathway leading up to your front entrance.
Renovate the Parking Lot
Because many staff, customers and visitors still arrive by car, it’s important to have a well maintained, safe and clean parking area. If your parking area will be used after regular daytime trading hours, it’s important to have adequate lighting to ensure the safety of potential customers or guests using it.
Open, unsecured parking lots were once the norm, but many modern parking areas add gates, shutters and security cameras. Security features can make the property more attractive to tenants and may help support its value. Prospective tenants are also likely to consider this type of premises.
Go Green
As of October 2026, governments, tenants and investors place considerable emphasis on the environmental impact of commercial buildings. In Australia, for example, the Commercial Building Disclosure (CBD) Program requires owners of office space of 1,000 square metres or more to disclose a NABERS Energy rating when they sell or lease it. It’s important to change the dated fixtures in your property to reduce your general carbon footprint.
Convert to energy-efficient light bulbs, increase insulation solutions and use recycled building materials where possible. The good news is you can advertise your property as an environmentally friendly space.
Supporting the environment and using recycled materials can enhance your reputation and widen the pool of potential tenants, including businesses with their own sustainability targets.
Final Thought
Many commercial properties become obsolete because owners don’t bother to keep the premises maintained or up to date with current trends. It may not always be easy to compete with developers who are putting up new, modern glass towers.
However, a few strategic renovations, facade improvements and plumbing system upgrades can go a long way toward keeping your commercial property competitive and in demand.
Which Commercial Property Upgrades Add the Most Value?
The upgrades that add the most value to a commercial property are the ones that make it easier to lease and cheaper to run. The table below compares the eight upgrades covered above by their main benefit and the main thing to check before starting.

How Do Energy Ratings Affect Commercial Property Value in Australia?
Energy ratings affect commercial property in Australia because many buyers and tenants compare buildings by their NABERS rating, and for larger offices the rating must be disclosed by law. A better rating gives an owner a measurable improvement to show for an upgrade.
What Is NABERS?
NABERS, the National Australian Built Environment Rating System, is a national initiative that measures and compares the environmental performance of Australian buildings and tenancies. It was formed in 1999 and is managed by the New South Wales Government on behalf of the Australian Government. Buildings are rated on a six-star scale, where zero is very poor performance and six is market-leading, across energy, water, waste and indoor environment quality. Each rating is valid for 12 months. Rated building types include offices, shopping centres, hotels, data centres, warehouses and cold stores.
What Does the Commercial Building Disclosure Program Require?
The Commercial Building Disclosure (CBD) Program, introduced by the Australian Government in 2010 under the Building Energy Efficiency Disclosure Act 2010, requires owners of commercial office space of 1,000 square metres or more to obtain a Building Energy Efficiency Certificate (BEEC) before selling, leasing or subleasing it, as of October 2026. The threshold was lowered from 2,000 to 1,000 square metres on 1 July 2017.
A BEEC contains a NABERS Energy star rating for the building and a Tenancy Lighting Assessment for the relevant areas. BEECs are valid for 12 months and are published on the public Building Energy Efficiency Register.
Is the CBD Program Expanding?
Yes. A roadmap for the CBD Program released on 14 October 2025 sets out a staged expansion through 2035, according to the Green Building Council of Australia. The first stages focus on mixed-use office buildings, large office tenancies, large hotels and public buildings, with retail, data centres and aged care to follow. Later stages are planned to add minimum energy performance standards and periodic disclosure. The Green Building Council of Australia also reports that buildings covered by the program cut their energy use by 40% on average between FY11 and FY23.
For an owner, this means energy upgrades such as efficient lighting, better insulation and modern heating and cooling are no longer only a cost saving; they also show up in a rating that tenants and buyers can check. The guide on turning a commercial space into an eco-friendly environment covers more practical green changes.
Do Renovations Have to Meet Accessibility Standards?
Renovations in Australia can trigger accessibility requirements. The Disability (Access to Premises — Buildings) Standards 2010 commenced on 1 May 2011 and apply when a building approval is sought for a new building or for an upgrade of an existing building. Their stated object is dignified, equitable, cost-effective and reasonably achievable access to buildings for people with a disability.
When you plan a major upgrade, ask your building surveyor or certifier early which access works the approval will require, such as entrances, paths of travel and accessible toilets, so they are budgeted from the start. Safe, even paths and good lighting also reduce the risk of visitors being hurt; see whether you are liable if someone falls on your property.
How to Plan a Commercial Property Upgrade Step by Step
- Assess the building: list the age and condition of the roof, plumbing, electrical, heating and cooling systems, and note any repeat repairs.
- Check demand: look at what similar buildings nearby offer and what tenants ask for, such as parking, end-of-trip facilities or flexible layouts.
- Get a baseline rating: if the building is an office, obtain a NABERS Energy rating so you can measure the effect of upgrades.
- Prioritise: fix safety and compliance items first, then upgrades that cut running costs, then cosmetic work.
- Check approvals: confirm with your local council and building surveyor which works need permits, including signage and any change of use.
- Use licensed trades: get written quotes from licensed plumbers, electricians and builders.
- Stage the work: schedule disruptive work between leases or out of hours where possible to keep existing tenants.
Before you commit to a big spend, it can help to revisit how to tell whether a property is a good investment and the key differences between residential and commercial construction.
Common Mistakes When Upgrading a Commercial Property
- Cosmetic work first: new paint does little if the plumbing or air conditioning fails in the first summer.
- Ignoring disclosure rules: offering a large office for lease without a valid BEEC breaches the CBD Program in Australia.
- Skipping approvals: unapproved signage, parking or change-of-use work can lead to orders to undo it.
- Leaving plumbing until it breaks: emergency repairs usually cost more and disrupt tenants; know the signs you should call an emergency plumber immediately.
- DIY on regulated work: some jobs must be done by a licensed tradesperson; see plumbing fixes you shouldn’t do yourself.
Frequently Asked Questions
What adds the most value to a commercial property?
The upgrades that add the most value to a commercial property are those that make it easier to lease and cheaper to run: a layout that suits current tenants, reliable building systems, better energy performance, secure parking and a clean, modern entrance. Purely cosmetic changes usually add less on their own.
How do I make an old commercial building look modern?
An old commercial building looks more modern with updated signage, a refreshed entrance, new doors and windows, modern light fittings, skylights where the structure allows, and a tidy outside area free of overgrown plants and debris.
Do I need a NABERS rating to lease my office in Australia?
Yes, if the office space is 1,000 square metres or more. As of October 2026, the Commercial Building Disclosure Program requires a Building Energy Efficiency Certificate, which includes a NABERS Energy rating, before the space is sold, leased or subleased. Smaller spaces can still be rated voluntarily.
How long is a NABERS rating valid?
A NABERS rating is valid for 12 months. A Building Energy Efficiency Certificate under the CBD Program is also valid for 12 months, so owners who lease regularly need to renew it each year.
Should I upgrade the plumbing in a commercial building?
Plumbing in a commercial building should be inspected regularly and upgraded when pipes, fixtures or valves are near the end of their life. A licensed commercial plumber can assess the system, check components such as thermostatic valves and quote for replacement.
