pigglepot, when I moved into my current house, my friends said it would take a couple of years for use to settle in and for it to feel like a home and it would take time for you to work out how best to use the space in a way that worked best for you as a family.
I thought they were talking out their arse.
I love our house. It ticked most of our boxes. But theres a couple of things that are problematic.
2 years on, I understand what my friends meant. I'm slowly finding the ideal space for everything, what furniture we need and what we don't, the best way to use the garden and to get the most out of it.
Its been a learning curve.
In that time I've look daily on rightmove as I'd got into such a habit with it. There's been houses I've liked and there's been 1 maybe 2 houses that in an ideal world perhaps would have been 'perfect' and ticked all the boxes we had instead of most of them. However knowing how long it took to sell our last house, knowing how stressful the move was and being realistic about the chances of getting that 'perfect' house I'm happy.
Create the vision of the best way you can live in your house rather than thinking about how nice it would be to have x, y or z.
Ironically, having spoken to friends about the way they live in their houses, I suspect that things on our wish list would probably drive me nuts in practice (eg DH wanted a garage. If we had a garage it would be a black hole I wouldn't be allowed to move things in and would turn into a dumping ground. Instead we have a smaller store area which has to be kept tidy and DH has think about where he puts stuff).
Your house sounds lovely. Reflect on the fact you could have the massive sunny garden and then never have the time/skills to do it justice and maintain it nicely and you'd forever worry about your children getting burnt. And grass grows faster in sunny gardens. Enjoy breakfast in the sun instead!
