Excuse my duh-ness but i'm having difficulty trying to follow whats going on here. Are these two photos an exact replica of your house and pool ? If not a hasty sketch with dimensions could help a lot. By kitchen wall do you mean the wall behind the bar ? And where is the pool wall ? Are you considering the covered area as being "inside" ? Sorry for all those questions lol Sometimes when you have a design problem you need to turn it inside out or on it's head. If you can't beat it maybe embrace it by making a feature of it : i.e. contrast by having the lightest colored pool surround and a great blue or tile inside and under the overhang, something that will echo the water color ? If you have a great covered area as in photo you'll most likely be spending a lot of time there and it could be soothing to be able to sometimes retire into a darker inside. In my book, 10M isn't small and also contrasting two floor colors doesn't necessarily make a space seem smaller and confined and may in fact even open it up. Could it be that you've thought yourself into a box here ? Sometimes one needs to give it all a good shake up and see how it resettles.

It depends on the species of wood (I.e. How hard or soft) and whether or not the ambient temperature can remain as stable as possible. What you caulk and paint in warmer weather may look great now, but when it begins to get colder, the wood begins to shrink, and the caulk will begin to pull away. This will look worse than if you didn't caulk at all. My suggestion is to use a caulk like the brand called "Big Stretch " in an attempt to avoid this.

No, sorry. Can't help. But if you copy and paste your answer in the Australian forum you may get more responses. If this is in the nz forum, aussies can't see it, but we see nz and Australia if we click nz as the country, in settings

Hi You will always see the joins if you look closely. There are two trains of thought . One is to make it a feature or try hiding it . The carport ceiling is hardie groove. Andrew
