Our gates are designed to look great and to keep your property safe and secure. Because no two sites are the same, we’ve got unrivalled experience in designing for challenging sites, including driveways, limited access points and awkwardly shaped sites. No matter how tricky your gate needs are, we’ve got a solution for you.

Gate options available

When your patio is planned and designed right you won’t want to leave it. At SIWA, we’re the experts in helping you design the right outdoor structure to help you get the most out of the space you’ve got. We also build custom carports.

Outdoor living is an essential part of Perth’s homes. At the forefront of a good looking deck is a quality constructed frame which helps support your deck and provides years of trouble-free decking. We provide custom-made solutions for your decking that add value and beauty to your property, in composite decking or solid timber.
