Architecture firm FreeGreen, which uses an open-source model to offer and market free and low-cost green house plans, last week unveiled itsTiny House lineup, which features plans for three houses that are, well, really tiny.

某些人的诱惑将是仅凭可爱的基础建造这些房屋之一。在第二座糖果碗中，这些碎片比呼吸薄荷大。每个计划均覆盖525平方英尺的内部空间，并设有一间卧室和一间浴室。设计风格是很小的传统，微小的质朴和现代的。后两个包括阁楼区域。

Access to the plans is available to those who pay $19.95 for a one-year “premium” Free Green membership or $99.95 for a “professional” membership. FreeGreen says a premium membership includes downloads of premium house plans, access to two house plans in AutoCAD format, product discounts and 50% off plan customizations from FreeGreen. The professional membership includes access to FreeGreen’s details library and unlimited plans in AutoCAD format.

When GBAfirst mentionedFreeGreen, on June 1, the firm was touting plans it had developed for a New England Colonial, now being built in Needham, Massachusetts, that will be a FreeGreen showcase home. The home’s owner, Rob Glazer, isbloggingabout the progress of the nearly completed project for the FreeGreen website.

Fee-based plans offered on the site range in price from $20 to $2,500. FreeGreen makes money through advertising from the manufacturers, contractors, and other companies whose products and services are paired with FreeGreen plans.
