All homes have their quirky moments, unusual corners, and odd angles. Some even have some bizarre rooms and downright peculiar architectural features. But where most homes share at least some basic conventions of location and spatial configuration, this year we've featured some unusual spaces that defy even these most basic assumptions.

"Unusual" is all relative, of course, but all of these homes, from the small to the large, from the seaworthy to the airborne, have presented unique design challenges for their owners, all of whom, I must say, have overcome them admirably.

In the water and in the clouds:
• Tracy & Marty's "Retro Metro" House Boat
• Callen & Eli's Artful Treehouse
• A Whimsical Treehouse in Whistler
• Lynne's Recycled Treehouse

Lofts and industrial spaces: To an extent, lofts and renovated warehouses have become commonplace, but there are still some transformed industrial spaces where the change is so inspiring, the use of space so clever, the softening of the hard edges so evident, the original use so unusual, or the demands of the labor so intense that they must be recognized.
• In the Warehouse: San Francisco Warehouse Turned Contemporary Loft
• Shirry & Boaz's Converted Auto Body Shop
• Kimmy & Nathan's Art Driven Loft
• Lauren & Nick's Home is Where the Heart Is: They've artifully managed to create a warm, inviting home out of a space with concrete floors and cinder block walls.
• Alina's Dar Gitane (Home of the Wanderer) House Tour: Alina inherited her loft from a woodworker who abandoned his tools and 20 years' worth of unwieldy work materials.

Other repurposed homes:
• Colman's One-of-a-Kind Converted Stable in Georgetown
• A San Francisco Shipping Container Home Office
• Dan'l's Caretaker's Apartment: Dan'l and his husband live in what used to be a caretaker's quarters above an old church that now boasts tricycles built into the front walls and a trapeze in the great room.
