I have been reading with avid interest the discussions at a
design and landscaping forum. One thought is bubbling to the surface: would you rather have a beautiful, lovely garden with a house plunked down in it--or would you rather have a house with a lovely garden?
Most of the books focus on the former. Gardens are entities in and of themselves. They should "relate" to the house, no doubt, but no one, not even when discussing the front yard says "the house is the focal point" of the landscape. And yet, isn't it? At least when you view it from outside.
The house has volume and space, it has forms and lines. Should that volume be reduced or enhanced by your design? Should the lines be softened or emphasised? It all depends, of course, on the type of house.
One concept that has ignited my enthusiasm is the idea of "enframing" the house. When garden books talk about "framing" they are talking about framing a view, or a focal point and almost never the house itself. The concept is instantly clear in this photo (which I stole from one of the threads at the Garden Forum.)

I have been advised that my plan is too boxy and that I need curves, that I am too inexperienced with gardening and plants to worry about design issues at this stage, and that I ought not to fight the "just off" symmetry of the house, but go with something asymmetrical, like a deciduous tree with perennial underplantings and a shrub or two on the left side of the house.
No matter. I am going to persist with the planning until I'm confident enough in the design to begin planting.
