Services
Custom Home Designs
We create bespoke home designs that reflect each client's unique vision and property characteristics. Our process begins with direct consultation with architecturally-trained builder Gary Green, who personally visits sites to understand their specific challenges and opportunities. Using a combination of line drawings and 3D conceptual models, we ensure complete client involvement in the design process to achieve perfect alignment with your dream home requirements.
Difficult Site Construction
Specialising in steep, rocky, and clay-based sites across Perth's hills, we transform problematic blocks into architectural masterpieces. Our expertise includes innovative solutions for bushfire regulations and terrain challenges, with extensive experience in timber-framed and pole home construction. We provide cost-effective alternatives to traditional brick construction while maintaining the highest standards of quality and safety in these complex environments.
Timber Frame Homes
Our timber frame and pole home construction offers energy-efficient solutions for challenging sites. This method allows maximised views and cost savings on site works while maintaining structural integrity. We combine traditional craftsmanship with modern techniques to create durable, aesthetically pleasing homes that complement Western Australia's natural landscapes and meet all Australian building standards.
Brick Homes
We deliver brick construction solutions for both standard and challenging sites throughout Perth. Our expertise extends to adapting traditional building methods for difficult terrain while maintaining aesthetic appeal and structural integrity. This service offers clients the option of classic masonry construction with our proven ability to overcome site-specific challenges that might deter other builders.
Home Additions
We design and construct custom additions of all types including multi-level expansions, carports, and specialty rooms. Our approach ensures seamless integration with existing structures while meeting modern building standards. From master bedroom suites to recreational spaces, we maintain the same quality focus and attention to detail that characterises all our construction projects.
