It’s a common dream: finding and affording a home where you can truly spread out. The mind reels with the possibilities: an enormous master bedroom, walk-in closets, a master bathroom that two people can use without bumping elbows, guest rooms and home offices, and reading rooms, oh my! But plenty of other people prefer a cozy and affordable (and, sure, probably more eco-friendly) small home in a great location—within walking distance from shops and restaurants, with good transportation links to work and cultural amenities.
