Proposed Two-Storey Dwelling with Pool & Pool House
Complying Development Certificate (CDC)
Project Overview
The Mulgoa Residence is a carefully designed two-storey family home created for a generous 954.80m² site. Designed under a Complying Development Certificate (CDC), the project maximises allowable floor area while maintaining full compliance with height, setback, and landscape requirements.
The result is a substantial 503.83m² total build area residence that balances scale, privacy, and functionality — complete with alfresco entertaining, swimming pool, spa plunge, and detached pool house.

The Brief
The client sought a spacious, contemporary two-storey home that would:
Maximise living space within CDC limits
Provide strong indoor–outdoor connection
Include a full-sized swimming pool and pool house
Deliver generous private open space
Maintain privacy from adjoining properties
Respond to solar orientation and prevailing breezes
The design needed to achieve maximum permissible GFA (25% lot area + 150m² allowance) while remaining fully compliant.
Site & Environmental Response
The site analysis identified:
Street noise and vehicle access from the front boundary
Potential privacy issues to adjoining properties
Prevailing summer and winter breezes
Solar movement (summer/winter solstice positioning)
The dwelling was positioned to exceed required setbacks, improving privacy and natural light access:
Front setback provided: 13.373m (exceeds requirement)
Rear setbacks (GF & FF): significantly exceed minimum controls
Side setbacks: exceed required 1.5m (GF) and 2.5m (FF)
Landscaping was strategically distributed between front and rear to exceed minimum requirements, achieving over 393m² of landscape area.
Design Strategy
The ground floor is designed as the primary family and entertaining zone, seamlessly connecting internal living spaces to the alfresco and pool area.
Ground Floor Highlights:
Open-plan kitchen, family, and dining
Covered alfresco (33m²)
Defined private open space (4m x 6m)
Direct access to 8.0m x 3.0m swimming pool
Integrated 1.5m x 1.5m spa / cold plunge
Detached pool house
Double garage with compliant driveway gradient
The first floor accommodates private family zones, maintaining separation between living and retreat spaces.
Architectural articulation at the front façade enhances depth while remaining within allowable articulation zone controls.
