A modern home commissioned by Lord Rothschild in Buckinghamshire England, built out of flint; a glass residence nestled next to a scenic lake in Switzerland; a treehouse that serves as a dream getaway for a family of five in New York.

Uncovering the world's most impressive escapes, including a home built into a lake.

An enchanting villa in the Spanish countryside; an ultra modern cliff-side retreat in the wilds of Switzerland; a cabin that resembles a pair of binoculars perched on a cliff in rural Quebec; a woodland retreat in Portugal.
