Custom timber decks built for Illawarra living
A well-built deck turns an unused yard into the best room in the house. Trademark Construction designs, builds and finishes custom timber decks across Wollongong and the Illawarra. Every deck is built for the coastal weather and made to last decades.

What our decks service includes
Every deck is designed around how you want to use the space, and built to suit your site, budget and home.
- New deck design and construction, from compact courtyards to large entertaining areas
- Deck replacements and repairs for tired, unsafe or rotting timber
- Hardwood, treated pine and composite decking to suit your budget and exposure
- Steps, handrails, privacy screens and built-in seating
- Integration with existing pergolas, patios and alfresco areas
Common problems a new deck solves
Most people call us because an outdoor space is not working. A yard that is never used, an old deck gone soft underfoot, or an awkward level change between house and garden. A considered deck fixes the access, the safety and the usability in one go.
