I love greyish coloured/weathered looking timber. I have done a concept design called "beach house" where I used the same coloured timber decking....I love it! Images are on my Houzz profile and website if you want to look. All the best :)

We are almost done - some metal artwork and filter box to go before planting. Thought you all might like to see what we ended up doing…. Pool & tiles by pool company, everything else done by ourselves. We are extremely happy with the waterline tile colour - they show up differently all times of the day which is a lovely surprise.

We built a pool exactly the same, however we didnt use laminated glass but a monolithic piece of 80mm thick Plexiglass 3mx2m from Germany. This reduced the overall cost of the pool considerably. Pool was fantastic and doubled as a water feature when not in use. Incorporating LED lighting allowed the pool to take on the mood of the night. The only downside we found with the pool was that after heaving swimming and sunscreen the waterline of the Plexiglass would need a clean. Other than that it gained lots of comments and was even used for photo shoots and promo work.

by the way, we had pebblecrete in our pool for 28 yrs. I think it was certainly very hardy ie. bits haven't come off. Algae can grow in the cement bits around the pebbles if you let the chemistry go off like after alot of rain. It was easy enough to scrape off and generally disappeared once I shocked the pool but it did seem to come back in the same spots again if I didn't keep close eye on the chemistry thereafter. The pebbles we had felt a bit roughish under foot, it's not a smooth surface. It was in no way uncomfortable to walk or sit on though. I would get it again, and still might if I don't like the sound of the glass....
