Case Study - Whitford

This Whitford property, located south of Howick in Auckland's southeast, sits on a sloping rural block with challenging ground conditions. The heavy clay soil tends to dry and crack in summer, then becomes unstable when those cracks fill with water in winter.

These conditions made the build highly complex, requiring 28 six-metre piles to stabilise the site before construction could begin. Our team delivered the complete concrete package – foundations, slab, and a three-metre in-situ wall – working closely with the architect, engineers, and other contractors to ensure a seamless result from start to finish.

Challenges

• Sloping site requiring advanced stabilisation and piling
• Architectural design featuring a large in-situ concrete wall with a decorative wood-grain finish
• Services embedded within the in-situ wall, including two abutting walls
• Under-slab and edge-beam insulation to meet strict thermal efficiency requirements
• Delivery of a high-quality polished concrete floor as part of the architectural specification

Our Solution

• Installed 28 piles, each 6 metres deep and 600mm in diameter, to stabilise the base and ensure long-term structural performance
• Formed and poured an insulated concrete slab for enhanced durability and thermal efficiency
• Delivered a premium polished concrete floor finish consistent with the architectural design
• Constructed a three-metre in-situ concrete wall using specialist formwork techniques to achieve the specified timber-grain texture
• Coordinated all stages with the architect, engineers, and inspection teams to maintain quality and compliance throughout

Results

The Project was delivered on time and with no inspection issues.

We achieved a high-end architectural finish that met the client's vision and the architect's exacting standards
