Congratulations on this terrific outdoor project, @Oreoprojects! Your spa deck and patio looks like a perfect place for relaxing and entertaining family and friends. I can imagine Oreo having a ball too.

It looks fantastic, will you be installing LED festoon lighting in the area, or do you have a different lighting system in mind? How long did it take you to build it? Did you run into any challenges while you were building it? Any extra information you can share about its assembly would be very much appreciated.
Again, thank you for sharing such a wonderful project.

Hi. Dave - 1
I installed LED downlights under the house eves which lights up the whole spa and entertainment area. The most difficult part was digging 16 holes 700 deep. Even with my hole borer it took three days to dig. I used 120x120 house piles for the poles. As per NZ building code i cut an L shape at the top of the pole to accomodate the 140 x 45 deck beam. Used the 140 x 45 timber to makes the bearers. Used to 140 x45 on either side and a 100 block in the middle. Then screwed both with a 12 gauge coach bolt. This too a long time. The whole project from start to finish took 6 weekends. I will post pictures of the poles, bearers etc. PS: as per building code I did not attach this deck to the house but buried poles along the house - spa deck is load bearing and if you attach to wall and things go wrong insurance will not cover you. Cheers
Afternoon @Oreoprojects
Ahhh Makes more sense now 
It looks good. I dont attach my projects to the house either (Think our insurance rules are different in Aus but not sure) I think a project should be able to stand by itself is usally my way of thinking. 6 weeks... lol That is a lot faster then I put my deck up, I really wouldnt class that as slow!
Every time I dig next to the hose for holes I end up running into the concrete foundation of the brick walls 😕 It looks like you were lucky It makes a difference dosnt it. How long since you put the spa in?
Thank you for the pics
Dave
