220 sq ft ultra-efficient home

The L41 home, designed by Architect Michael Katz and Artist Janet Corne is a 220 sq. ft. ultra-compact, sustainable, high-design, high quality, energy-efficient house. The L41 home makes it possible for the millions of people who otherwise could not afford to buy a house, to become homeowners.

And, quite amazingly, it is constructed from Pine-Beetle-killed cross-laminated timber.

L41 homes are stackable

  1. Very nice, but how much do they cost?

    The designers haven’t set a price yet — and they don’t want to tell how much the prototype cost, because that would be misleading.


    The L41 is not available currently, and is seeking a manufacturer.

    I imagine the cost will be around that of other modular modern homes, in the range of $120 (for the shell) to $195 (to build, exclusive of interior fittings) … so $250 / sq ft, plus land?


    This would equal $55,000 for the home alone — not cheap.

    We might be better off if somebody brought to market a modernized quonset hut.
