Facade Design for Apartment Buildings in Australia

Australian apartment buildings require non-combustible facade systems that meet NCC Class 2 construction requirements while delivering the design variety that architects and developers expect. The facade is typically the single largest visual element on an apartment project, and the material and system choices made at specification stage affect compliance, programme, cost, and long-term maintenance for the life of the building.

This guide covers the regulatory framework for apartment facades, current design approaches, how different facade systems serve different parts of the building envelope, and the practical considerations that shape specification decisions on Class 2 projects.

What does the NCC require for Class 2 apartment facades?

Class 2 buildings - apartments and residential units where people live above or below each other - fall under NCC Volume One. The construction type required depends on the building’s rise in storeys:

Type A construction applies to Class 2 buildings with a rise of four or more storeys. This covers the majority of mid-rise and high-rise apartment projects across Australia.
Type B construction applies to two and three-storey Class 2 buildings.

Under both construction types, the NCC requires external walls - including the facade covering, framing, insulation, and supporting elements - to be non-combustible. Under C2D10 of NCC 2022, aluminium and aluminium alloy are explicitly deemed non-combustible when the material is entirely composed of itself. This means solid aluminium facade systems satisfy the non-combustibility requirement through the Deemed-to-Satisfy (DtS) pathway without the need for fire engineering assessments or large-scale facade fire testing.

This matters in practice. Where combustible or composite materials are proposed, projects typically require alternative solutions involving fire engineering reports, AS 5113 classification testing, or performance-based assessments - all of which add time, cost, and approval risk. A fully non-combustible aluminium facade system simplifies the compliance pathway considerably, which is why aluminium has become the baseline material for apartment facade design in Australia since the cladding crisis.

Why has non-combustible cladding become the baseline for apartments?

The combustible cladding crisis that followed the Grenfell Tower fire in 2017 and the Lacrosse building fire in Melbourne fundamentally changed apartment facade specification in Australia. State-by-state cladding audits identified thousands of Class 2 buildings with non-compliant facade materials - predominantly aluminium composite panels (ACP) with polyethylene cores.

The regulatory response tightened enforcement of existing NCC non-combustibility requirements and introduced additional scrutiny through state-level legislation. NSW established the Design and Building Practitioners Act (DBPA) with mandatory declarations for fire safety-related building work. Victoria’s Cladding Safety Victoria programme identified over 500 buildings requiring rectification. Queensland, South Australia, and Western Australia implemented similar audit and remediation frameworks.

The practical effect is that specifying anything other than a non-combustible facade system on an apartment building now creates additional compliance burden, certification risk, and potential insurance exposure. Architects and developers overwhelmingly prefer materials that satisfy the DtS pathway cleanly. This is the environment that has made solid aluminium the default face material for apartment facades across Australia.

What are the current design trends in apartment facade design?

Apartment design has moved well beyond the monolithic glass-and-render towers of the early 2000s. Current design trends are driven by planning controls, design review panels, and a market that increasingly values facade articulation. Several patterns appear consistently across apartment projects in NSW, Victoria, and Queensland.

Mixed-material facades

Most apartment buildings now combine multiple facade materials and systems across the building envelope. A typical arrangement might use a curtain wall or glazed system for the ground-floor lobby and retail frontage, a rainscreen cladding system for the residential tower levels, solid panels for feature elements, and aluminium battens for balcony screening and plant concealment. This layered approach satisfies design quality requirements while keeping each system in the zone where it performs best.

Colour and texture variation between levels

Design review panels - particularly in NSW under the State Environmental Planning Policy No 65 (SEPP 65) and the associated Apartment Design Guide - expect facade articulation that breaks down building bulk. One common approach is to vary cladding colour or orientation between floor zones. A building might use a darker tone at podium level, a lighter colour for the mid-rise residential floors, and a contrasting accent at the top. Aluminium systems support this through powder coating and anodising in a wide colour range without changing the underlying system or installation methodology.

Balcony integration and screening

Balconies are a defining feature of Australian apartment design and a key facade design element. Privacy screening between units, wind mitigation, and plant room concealment all create scope for aluminium battens and screening systems. The balcony zone often represents 15 to 25 per cent of the total facade area on a residential building, making it a significant scope item in its own right.

Soffit and underside treatment

Soffits - the undersides of balconies, awnings, and projecting elements - are frequently specified in aluminium. They are exposed to weather and visible from the street, so the finish and material need to be durable and consistent with the broader facade design. Soffits are easily overlooked in early-stage facade specification but represent meaningful scope on apartment projects.

How do different facade systems serve an apartment building?

One of the practical advantages of aluminium as a facade material is that a single supplier can address multiple facade conditions across a building with systems that share the same material, finish range, and compliance documentation. On a typical apartment project, four distinct systems from Valmond & Gibson might be deployed across the envelope.

165CW unitised curtain wall - podium and commercial levels

The ground floor of an apartment building typically includes the lobby entry, retail or commercial tenancies, and common areas that benefit from large glazed openings. The 165CW unitised curtain wall system serves these zones. Designed, engineered, and extruded in Australia, it accepts insulated glazing units from 24mm to 40mm thickness and includes thermally broken glazing adaptors - relevant for energy efficiency compliance under NCC Section J. The unitised approach means panels are factory-assembled and craned into position, which suits the fast programme requirements of apartment construction.

interloQ interlocking rainscreen - residential tower levels

interloQ is an interlocking aluminium rainscreen system that suits the repetitive wall areas on residential floors. Apartment buildings have consistent floor-to-floor heights and window configurations that align with interloQ’s modular panel system. The panels interlock mechanically, install vertically or horizontally depending on the design intent, and individual panels can be replaced without disturbing adjacent panels - a meaningful maintenance advantage for a building that will be occupied for decades.

The rainscreen principle - a drained and ventilated cavity behind the panels - manages moisture effectively and supports the condensation management requirements under NCC Part F8. interloQ is CSIRO-tested to AS 1530.1 as non-combustible (report FNC12595) and tested to AS/NZS 4284 for weather performance at 1500Pa serviceability limit state. Alloy 6060/6063, T5 temper, 1.8 to 3.5mm thickness. Available in powder coat, anodised, woodgrain, and custom finishes.

element13 solid aluminium panels - feature areas and accents

element13 is a 3mm solid aluminium panel with PVDF paint finishes. On apartment projects, it typically appears as entry feature walls, accent panels, and soffits where a flat, precise panel aesthetic is required. The PVDF coating (PPG, tested to AAMA 2605) provides superior UV resistance and colour retention, which matters on facades that receive sustained sun exposure - particularly north and west-facing elevations in Australian conditions.

element13 is CSIRO-tested to AS 1530.1 as non-combustible (report FNC12545) and carries comprehensive fire testing including ignitability, flame spread, heat release, and smoke development (CSIRO report FNE12552 - scores of 0, 0, 0, and 1 respectively). Available in over 30 standard colours across solid, metallic, woodgrain, and imitation ranges, with custom colour matching for larger orders. Weight is 8.13 kg/m2 at 3mm thickness.

conneQt aluminium battens - balcony screening, fins, and soffits

conneQt is the batten and adaptor system that addresses the articulation and screening scope on apartment buildings. Balcony privacy screens, plant room concealment, architectural fins, and soffit battens all fall within conneQt’s scope. It works as a standalone system or in combination with interloQ and element13, using the same aluminium alloy and finish options for visual consistency across the facade.

On a typical 8 to 12-storey apartment project, the balcony screening and soffit scope supplied through conneQt can represent a meaningful portion of the total facade supply value. It is a scope area that is sometimes missed in early takeoffs but is almost always present.

What role does SEPP 65 play in apartment facade design?

In NSW, the State Environmental Planning Policy No 65 and the accompanying Apartment Design Guide (ADG) set qualitative design standards for residential apartment development. SEPP 65 requires that apartment buildings be assessed against the ADG’s design criteria, and local design review panels evaluate proposals against these principles.

From a facade perspective, the ADG pushes for building articulation, visual interest, material quality, and a considered relationship between the building and the street. Projects that propose flat, undifferentiated facades typically receive design review feedback requesting greater articulation - which often means introducing material variation, colour changes between levels, expressed balcony elements, or feature panels.

The multi-system approach described above - combining curtain wall, rainscreen, solid panels, and battens across a single building - directly responds to these design quality expectations. The ability to vary colour, orientation, and system type within a consistent non-combustible material palette gives architects the design freedom that design review panels expect, without introducing compliance risk.

Similar design quality frameworks operate in Victoria (Better Apartments Design Standards), Queensland (accepted development requirements), and other states. The trend is consistent: planning authorities expect facade variety on apartment buildings, and the specification needs to deliver that variety within the NCC compliance framework.

The multi-system advantage on apartment projects

The Class 2 apartment market is where these systems come together most frequently. A single building might use all four Valmond & Gibson product lines - 165CW at ground, interloQ on the tower, element13 for features, conneQt for screening and soffits - with a single compliance documentation package, consistent colour options across systems, and one supplier relationship for the facade installer to manage.

All products carry up to 20-year warranties when installed by a qualified installer, are 100 per cent recyclable, and are supported by CSIRO-tested compliance packs that include non-combustibility certificates, weather performance testing, and structural assessments. The documentation package is designed to give certifiers exactly what they need to sign off - without gaps or ambiguity.

For architects designing apartment buildings and developers assessing facade options, the practical question is not just what the building looks like on day one, but whether the facade system will perform, maintain, and remain compliant for the building’s operational life. On Class 2 projects, that is typically measured in decades.
