Hello Avilife, i have a Suggestion for House, if you can remember the Luxury Weekend Lake House of Playstation 3 Home. At sea and surrounded by Tree at behind with a beautiful garden way along green bushes and lights, that heading to Trees. It was one of the best retreat spaces ever, alot of people loved it and it was my favorite House. I have posted a few pictures that similar, and some other examples too!
It does not have to be that huge or overloaded with furnitures, what's the matter is it has nice atmosphere, that people feel comfortable staying there. You can generate it with some lights.
