View Full Width
Spiire is providing civil engineering and construction consultancy services for the development of Air at Strathalbyn, located in the heart of the Fleurieu Peninsula.
This new Wel.Co development will offer 109 premium lots in a boutique community situated in the regional town of Strathalbyn.
Perched in an elevated position, Air at Strathalbyn offers picturesque views amidst an already established local town, in close proximity to the Strathalbyn Town Centre and key facilities.
Spiire’s local Adelaide team is engaged to provide civil design and construction consultancy services from Stage 2 of the estate. Our Civil Engineering team is responding to the site’s significantly steep rocky topography, which presents challenges for road grading, lot benching and retaining wall strategy.
The site also contains a number of significant trees and native vegetation which is required to be preserved. Earthworks, roads and services has been sensitively designed to retain and protect these valuable natural assets.
Working closely with our client, our team produced feasibilities on a range of options to provide an optimal lot grading solution that minimises costs associated with overall earthworks, benching and retaining. The resulting lots offer purchasers the benefits of considerable space and scenic vantage points, with lot sizes ranging from 663 to 2,000m²
The agreed methodology will be rolled out across Stages 3 and 4, with detailed design currently underway. Our team’s design responds to stormwater management requirements to protect local waterways, as the development outflows into an existing detention basin and wetland.
We are also upgrading the existing sewer pump station with additional storage to facilitate development of the balance of the site. Stage 2 construction is underway, with completion of stage 2 scheduled for July 2026.
We look forward to seeing the Air at Strathalbyn community continue to grow as works progress on site.
