Yes, you can install a timber flooring apartment upgrade, provided you meet strict acoustic requirements and body corporate guidelines. Because hard floors transmit impact noise to the units below, upgrading from carpet to timber requires careful planning. You will need to submit a formal request to your owners corporation, select an acoustic underlay that meets National Construction Code (NCC) standards, and choose a timber profile suited for installation over a concrete slab.
Before You Start: Apartment Flooring Checklist
| Step | Action Required |
| 1. Check the Rules | Review your specific owners corporation rules regarding hard flooring replacements. |
| 2. Source Acoustic Data | Obtain manufacturer acoustic test reports for your chosen underlay. |
| 3. Submit for Approval | Provide flooring specs, underlay data, and installer details to your strata manager. |
| 4. Select the Timber | Choose a structurally stable board (e.g., engineered timber) suited for concrete slabs. |
| 5. Book Logistics | Arrange loading bay access, lift padding, and trades parking for installation day. |
Can You Install Timber Floors in an Apartment?
In most Victorian apartments, you are permitted to install timber flooring, but it is rarely a straightforward process. Unlike a freestanding house, an apartment building is a shared structural environment. Changing your flooring changes the acoustic profile of the building.
Even if your building does not have a specific by-law restricting hard floors, standard noise obligations under Victorian strata law still apply. Residents have a legal right to the peaceful enjoyment of their property. If you install timber flooring strata rules do not explicitly forbid, but it results in excessive noise transmission, you can still be held liable. Therefore, conditional approval based on acoustic performance is the standard pathway for these renovations in Melbourne.
Owners Corporation Approval in Victoria
Before purchasing materials or lifting your existing carpet, you must secure owners corporation approval. Start by checking your building’s registered rules. Many modern Melbourne developments have specific bylaws dictating the acoustic rating required for any hard flooring apartment noise mitigation.
When submitting your application to the owners corporation committee or strata manager, you generally need to provide:
-
The exact type and brand of timber flooring.
-
The specifications of the acoustic underlay.
-
Laboratory or field test acoustic data for the underlay system.
-
The contractor’s details, including their public liability insurance.
Approval usually carries conditions, such as restricting installation work to specific weekday hours and mandating post-installation acoustic testing. Always verify current strata legislation on the Consumer Affairs Victoria website before commencing work, as proceeding without written approval can result in disputes.

Noise Between Apartments: What Actually Matters
When discussing flooring in multi-residential buildings, noise is categorized into two types: airborne noise (voices, music) and impact noise (footsteps, dropped items, moving furniture). Timber floors primarily exacerbate impact noise.
In Australia, impact noise transmission is measured using the LnTw (Weighted Standardised Impact Sound Pressure Level) metric. Explained simply, the LnTw rating measures the amount of noise that makes it through the floor to the apartment below. A lower LnTw number means less noise is transmitted.
The National Construction Code (NCC) mandates a maximum LnTw of 62 for floors separating dwellings. However, many premium Melbourne apartment buildings enforce stricter standards, often requiring an LnTw of 55 or even 50.
The effectiveness of your flooring system relies heavily on the building’s existing structure. A 200mm thick concrete slab will inherently block more noise than a 150mm slab. Similarly, a suspended plasterboard ceiling in the apartment below will absorb more sound than a bare, painted concrete ceiling. Ignoring these factors is risky; there have been multiple Victorian Civil and Administrative Tribunal (VCAT) cases where apartment owners were ordered to cover or completely remove newly installed timber floors because they breached noise regulations.
Acoustic Underlay Options
The acoustic underlay is the most critical component of an apartment flooring project. You cannot simply use a generic residential foam; the underlay must be engineered to decouple the rigid timber floor from the concrete slab.
There are two primary systems for acoustic underlays:
-
Adhesive-fixed systems: Acoustic matting (usually recycled rubber or cork) is glued directly to the concrete slab, and the timber floor is then glued to the matting. This provides a highly stable, premium feel underfoot.
-
Floating systems: The acoustic underlay is rolled out loosely over the slab, and the timber boards are locked or glued together over the top.
Do not rely on generic product claims. Ask your flooring supplier for manufacturer test data that closely matches your building’s specific slab thickness and ceiling configuration. In luxury developments or buildings with strict noise bylaws, the owners corporation may require you to engage an independent acoustic engineer to certify that your proposed acoustic underlay timber flooring system will meet the required LnTw rating.
Best Timber Floor Types for Apartments
Concrete slabs in high-rise buildings are subject to temperature fluctuations and structural movement. Selecting the right board profile is essential for longevity.
Engineered Timber
An engineered timber flooring apartment installation is widely considered the best choice. Because engineered boards feature a top layer of real hardwood bonded to a cross-directional plywood core, they are highly resistant to moisture and temperature changes. This structural stability makes them ideal for direct-stick installations over concrete and acoustic matting. They also allow for the wide-board aesthetic that is highly sought after in modern Melbourne interiors.
Solid Timber
While traditional solid timber offers longevity, its application in apartments is limited. Solid timber is highly reactive to moisture and temperature, meaning it cannot be glued directly to a concrete slab without a sub-floor (like plywood or battens). This sub-floor raises the floor height significantly, which often causes clearance issues with existing apartment doors, skirting boards, and kitchen cabinetry.
Parquetry
Parquetry, including herringbone and chevron patterns, can be successfully installed in apartments. Like engineered planks, engineered parquetry blocks offer the stability required for concrete slab installation while delivering a high-end architectural finish.
Choosing a style: For smaller apartments, light-toned oak and wider boards can make the space feel larger and more open. For a detailed breakdown of board construction, read our guide on

Installation Methods Over Concrete Slabs
Installing timber flooring over concrete slab structures requires precision and extensive preparation.
Glue-Down Installation
A glue down timber flooring installation is the preferred method for high-end apartments. It eliminates the hollow sound associated with floating floors and feels as solid as a traditional floor. The boards are adhered directly to the acoustic matting, which is adhered to the slab.
Floating Installation
Floating floors are faster to install and generally more cost-effective. The boards click or glue together at the joints, resting entirely on the underlay. While acoustic performance can be good, they do not offer the same solid foot-feel as a glue-down floor.
Slab Preparation
Regardless of the method, the concrete slab must be prepared properly. Installers will conduct moisture testing to ensure the slab is dry. If the slab is uneven a common issue in commercial concrete pours a self-levelling compound must be applied. Installing timber over an uneven slab will result in bouncing boards, squeaking, and potential failure of the locking mechanisms. Installers must also leave adequate expansion gaps at all perimeter walls to allow the timber to expand naturally.
Cost and Timeline for a Timber Flooring Apartment Project
Several factors drive the cost of apartment flooring installations beyond the price per square metre of the timber itself.
Key cost drivers include:
-
Acoustic Underlay: High-performance rubber acoustic matting is significantly more expensive than standard foam underlay.
-
Slab Preparation: Grinding concrete and applying levelling compounds adds labor and material costs.
-
Logistics: Melbourne CBD and inner-suburban apartments require careful logistical planning. Booking loading docks, reserving trades parking, and moving materials up via goods lifts all add time to the project.
A standard two-bedroom apartment typically takes three to five days to complete, assuming the slab requires minimal leveling and the goods lift is readily accessible.
Care and Maintenance in an Apartment
Melbourne’s climate varies drastically, and this affects indoor environments. Many apartments rely heavily on reverse-cycle air conditioning, which can aggressively dry out the air. Low humidity can cause timber floors to shrink or cup. Maintaining a stable indoor temperature and humidity level will protect your boards.
In high-traffic zones, use rugs to protect the floor from wear. Always attach felt furniture pads to the legs of dining chairs, tables, and couches to prevent deep scratches. If your floors look worn after several years of use, an apartment floor sanding and polishing service can restore them, provided the timber wear layer is thick enough. Read our comprehensive guide on
Does Timber Add Value to an Apartment?
Upgrading from carpet or laminate to high-quality timber is a proven way to increase buyer appeal. Real estate developer studies consistently show that a significant majority of property buyers often around 70% prefer hard timber floors in living areas over tiles or carpet. Timber provides a neutral, premium foundation that suits various interior styles, making the property easier to sell or lease. For more details on property valuation, see

FAQs
Can I put timber floors in a unit above another apartment?
Yes, installing timber floors in units above others is allowed, provided you use an approved acoustic underlay that meets the building’s noise transmission limits and obtain formal owners corporation approval.
Do I need owners corporation approval?
Yes. Even if your building does not have specific hard flooring bylaws, standard nuisance and noise regulations mean you must seek approval from your owners corporation timber flooring committee before starting work.
What underlay do I need for an apartment?
You need a specialized acoustic underlay, such as high-density rubber or cork matting, designed to reduce impact noise (measured by an LnTw rating) to comply with NCC and strata requirements.
Is engineered or solid timber better for apartments?
Engineered timber is highly recommended for apartments. It is more stable over concrete slabs, less susceptible to moisture and temperature fluctuations, and avoids the height clearance issues associated with solid timber sub-floors.
How do I stop noise complaints?
Prevent noise complaints by using a premium acoustic underlay, ensuring professional installation, and placing area rugs in high-traffic zones or under heavy furniture to absorb impact noise.
Can timber be laid over existing tiles?
It is possible to lay a floating timber floor over existing tiles if the tiles are perfectly flat, secure, and undamaged. However, this raises the floor height significantly. For the best acoustic and structural result, removing the tiles and preparing the bare concrete slab is recommended.
