You may not be able to afford the house of your dreams, but you can still own some prime real estate. Birdhouses are going up in many back yards these days, and with architects and artists getting into the act, there are styles to suit every taste. Buyers will find copper roofing, whimsical painted facades, stately mansions and Federalist churches. Some are brand-new, others are antiques, and many are made with the time-honored building techniques of craftsmen around the world. Whatever the case, they are enough to make any bird leave the nest and move uptown.
