I can imagine how beautiful your home will be after all those descriptions and wishes. I know it'll be a lovely place wherever it may be.
You are still young and hopefully your dream house will eventually be a reality. As for the half year France and half year Philippines, do it while you are still young.
We have been there since we live in Andalucia for quite sometime now (more than 25 years). We used to live half/half too, but over the years as we aged, lol... it's not sustainable anymore particularly when you are travelling with a huge dog.

We reduced the stay in Southern Spain from 6 months to 3-4 months.. The one thing we are concerned about is the proximity of hospitals as we live on the mountain. Now we are about to sell the property. We have no plans yet on what we'll do next when the house gets sold.
Make your dreams happen..think of the pros and cons....then decide. Wishing you a lovely evening!
