Thank you, bdfd and VeroniQ. I guess because I've lived with the style of homes found here in the US, they seem to be plain to me.
I was being silly when I was trying to render a picture of this house; I had it completely furnished (on the inside) and it was at 46.2 MB compressed! No wonder I was having trouble!
So, I saved it as a separate file and emptied out the furniture (except for the lighting and built-ins of course). It's now at 17.6 MB compressed and I've been able to get a rendered front aerial picture. I did keep the vehicle, just moved it outside as decoration. [:))]
And once I got that rendered, the mustard yellow stucco has become a lemon yellow stucco! [:-&] [:-&] [:-&] I'm getting rid of the yellow (thank you for your advice on that, bdfd) and replacing it with a basic roughcast texture from the library.
So, now I can overload that file with decorating the patio and get a picture of that as soon as I can. [:D]
