Box Span subfloor topped with 140mm merbau decking boards
My 2 dealings with Spantec have both been great. The design, ordering and pickup/delivery was painless and when it came to building on site, it was so easy to erect that it was done in 6 hours!
The subfloor was engineered to handle the load of our spa as well as a decent crowd for entertainment purposes. The subfloor is bolted to the house along 2 walls and has 12 ezipiers supporting the main area. The subfloor was set at a height that meant i was able to bring the decking boards over our existing concrete alfresco area making it all one seamless entertainment area. I then ordered an addional frame and 2 ezipiers to make a platform off the deck that has a 5 stair stringer attached for access to the back yard.
I made a privacy wall which the frame of is bolted to the existing ezipier legs.
The deck will eventually have an insulated panel roof over the area. (Hopefully by summer)
