Evolution Precast delivers striking arched façade for Gold Coast residence

National Precast Concrete Association of Australia

Clean curves, refined finishes and seamless detailing can create the impression that a building’s defining elements came together effortlessly. In reality, achieving that level of precision often requires significant planning, coordination and manufacturing expertise long before construction begins.

The project required complex curved geometries, deep sections and tight tolerances to achieve the home’s distinctive architectural façade.)

This challenge becomes even greater when a design combines large-scale curved forms, tight tolerances and premium architectural finishes within a single façade system.

Evolution Precast recently encountered this challenge while delivering a striking arched façade for a private residence on the Gold Coast.

The company was engaged to manufacture and supply 31 arched precast façade panels, together with a precast chimney face panel and a monolithic four-sided fireplace crown featuring arched apertures.

The façade formed the defining architectural feature of the residence. The client sought a bold architectural outcome capable of achieving significant depth, curvature and finish quality while maintaining precise alignment across the structure.

Precast concrete was selected for its ability to create the large-scale arches and substantial element depths required while maintaining dimensional accuracy and surface quality throughout the façade system.

The completed architectural façade incorporated rendered precast arches with imported hand-painted glazed tiles and cobalt blue gloss porcelain finishes installed during the final finishing stages.

The completed residence features 31 custom precast arches manufactured by Evolution Precast, combining complex curved concrete forms with imported hand-painted glazed tiles to achieve a seamless architectural façade.

Delivering architectural complexity

The project incorporated arches of varying radii, with the largest precast elements reaching 6.5 metres in length, up to 600mm thick and weighing as much as 15.5 tonnes. Several panels also featured complex double rebates through the arch cross-sections to create architectural detailing and accommodate the glazed tile finishes.

Achieving the desired visual impact required significant depth, curvature and detailing while maintaining tight installation tolerances.

While the completed façade appears elegant and seamless, delivering these elements introduced a series of manufacturing, handling and installation challenges.

Several panels incorporated a full central arch with adjoining half arches on either side, requiring careful consideration of casting geometry, reinforcement placement and lifting constraints. To remain within crane limitations during transport and installation, some arches were split at the apex prior to erection.

Manufacturing and handling complexity

The panels were cast flat on steel casting beds using large custom-cut XPS foam sections fixed directly to the casting table to create the arch profiles and rebate geometry.

Due to the substantial 600mm section depths, considerable attention was required around edge shutter stability and bracing performance during pouring operations. Additional temporary bracing systems were incorporated throughout casting to minimise movement and maintain dimensional tolerances.

Handling and de-moulding procedures also required careful sequencing due to the delicate rebate details incorporated into the panels. Multiple strongbacks were used during tilt lifting operations to stabilise the elements and reduce stress concentrations during handling.

The rebate foam sections were progressively stripped during de-moulding to minimise the risk of edge damage and preserve the finished architectural detailing.

Reinforcement detailing added another layer of complexity. The steel cages were modelled in 3D using Revit to assist steel fixers with bar placement and coordination during manufacture. The reinforcement cages were then carefully lifted into position during production.

Precision during installation

Although Evolution Precast’s scope was supply only, the company worked closely with installation teams throughout delivery to help ensure façade alignment tolerances were maintained on site.

This became particularly important due to the reduced 10mm vertical panel joints specified across the façade, significantly tighter than conventional precast jointing arrangements.

The reduced joint width was critical to achieving the intended rendered façade appearance. However, it also increased installation sensitivity and placement accuracy requirements on site. 

With panels positioned in close proximity during erection, lifting operations and alignment required careful coordination to minimise the risk of edge chipping or damage during placement.

The project’s monolithic fireplace crown presented an additional manufacturing challenge. The four-sided precast unit was cast upright as a single element, requiring suspended custom XPS aperture profiles to be integrated into the formwork system during production.

Collaboration from design to completion

Close coordination also occurred during the finishing phase. Evolution Precast worked closely with the client during the tile selection phase, reviewing sample tiles against the rebate details to confirm suitability prior to final selection.

Factory reviews and sample checks were undertaken before the final tile selection to confirm dimensional suitability and detailing integration.

Coordination also extended to other subcontractors, including renderers, to ensure render beading systems aligned correctly with the reduced façade joint dimensions and architectural detailing requirements.

The completed residence demonstrates how precast concrete can support highly customised architectural outcomes while accommodating the practical realities of manufacturing, reinforcement placement, transport, lifting and installation.

More importantly, the project highlights the value of early collaboration, detailed planning and manufacturing expertise in transforming complex architectural concepts into built reality.
