Thanks :) Yeah decided to go with tile. So sand cement is ok over existing tiles if I prep them first? Only problem is, the new pad can only be about 30mm at it's thickest (leaving up to 15mm for tiles) otherwise it'll end up being higher than the hallway floor. So I either need to make the fall shallower or not bother with the waste and make it all level. If I made it level, could I use levelling compound at that thickness or would deck mud/sand cement be the best option? Also, should I be putting in mesh for strength? (I know I should (and will) ask the local hardware what they suggest, but it's great to have suggestions from the Houzz community also)

Great work guys! Would've been interesting to see what the garden was like before colourwise but hey, guess you can't win them all. Love the patio in the backyard, I bet you have some very happy customers!

I am wanting to get a pool put in (not too big ~7.5m x4m) - the section slopes off quite a bit and the height of the house is about a story above the ground at its highest point. Im just after some ideas for layout and how to get a good flow from the deck above - there are 2 bigger decks (covered and uncovered plus the wrap around). The covered deck which has bbq and table and chairs is above the green water tank and connects with the kitchen nicely (id quite like to hide that tank somehow), the open deck connects with the lounge area inside. Long term plan is to have a covered space with outdoor kitchen, bathroom and space for dining and lounge settings beside the pool. It has a great view of the ocean from the house ( and the section below up to meter or 2 from the fence line). there is septic tank in line with the green water tank (so don't want to get too close to that). This is in the tropics, so shade and shelter is a must - the sun follows the open deck across to the covered deck side and the house is on the west more sheltered side of the island. Any ideas would be appreciated. The last picture is of the house in front, it is very close to the fence line, but is a lot lower down.

I suspect your best course of action would be to contact a local engineer and/or builder -- without knowing what area you are in , and local rules and regulations , any advice wouldn't be much value from us , and quite possibly won't meet compliance .
