Living here in DC, most of my clients crave beautiful ways to make their tiny row-home seem more spacious. Yeah, that's right, "spacious". A row house. I don't know if everyone's aware, but most homes in this area are between 12-15 feet wide. "Spacious and roomy" can be a tall order around here.
There are a few little tricks I've learned to offer some additional "visual square-footage". One of those tricks is keeping an eye on the bases of furnishings.
I've learned through trial and error that furnishings that are up off of the floor seem to have a significantly smaller footprint, visually. They take up less space, allowing you to see beneath them. You don't want everything in a room to follow the same rules, things get strerile and stiff really quickly that way. So not all pieces should abide by this rule, but I definitely try to keep the largest pieces up on some spindly legs if I can. I really love Ikea's hairpin legs for making things feel weightless. They suit a desk or buffet and can be painted easily to your liking. I've gathered a few examples of spindly hairpin legs that I think are just beautiful.
Here are a few other examples of light and airy furnishings.
