for one of our homes we stole some ideas from German and American floor plans that included an upstairs master suite with under sloping ceiling space for wiw and ensuite and we also had a kitchen with WIP, dining and family room without TV and a separate lounge "media room" that was also useful for guests or formal dining on special occasions....that home also had my favourite compartmented bathroom that is ideal for sharing and i probably stole many ideas from some upmarket display homes but i was lucky enough to have grown up in a family of builders were i was often exposed to some spectacular architect designed homes and touring exhibition homes villages in Sydney was a regular weekend activity... i suggest that you study a familiar home to clarify what size and spaces are good and bad for you, measure rooms, doorways, windows and furniture and make a scale drawing and a wish list, must haves and can live withouts and carry a compass and a steel tape measure so you can easily check orientation and spaces of anything that takes your fancy....these days we can make an Ideas book of photos on HOUZZ but i also keep a collection of books, magazines, catalogues etc but keep in mind when inspecting exhsibition homes you will find that what looks great when set up by a designer with smaller furniture and no extra clutter might feel cramped in a comfortable family home and i agree that not being forced to cull belongings makes us think that we need more storage when in fact we probably need much less "stuff" says the person who needs a whole separate room for my reference books!!
