The 100K House project is a case study started by a small development team in Philadelphia. Two homes are being built first and the name of the project comes from the target construction cost for the smaller of the two homes. The homes will have a modern and green design and the goal of the case study is to prove that green homes can be built affordably if designed properly.

Underlying Concept of the 100K House
The basic concept of the 100K House is to offer an affordable home that places a high priority on quality, design, energy efficiency, health and sustainability rather than “bells & whistles” that can drive the price of new construction out of reach from the majority of home buyers.
The majority of consumers today flipping through the pages of Dwell magazine and similar publications are dreaming of a modern and green home that is out of reach for them on their average income. Most are earning above the median income but well below six figures. They can not qualify for subsidized housing nor can they afford the green and modern homes that are being sold for half a million dollars and up. The only options are to purchase a new construction home of poor quality and design or to purchase an old home and go about the arduous and expensive task of rehabing it themselves to fit their tastes.
The 100K House is an attempt to offer a product to this demographic that is not being currently served. The home is greatly simplified by reducing the footprint, stripping down the finishes to a very basic level and arranging the layout in a very efficient manner. A high priority is placed on the modern architectural design as well as the most cost effective green building materials and methods in order to provide the greatest value at the lowest price to a discerning client. The majority of the construction budget if focused on providing the best envelope and mechanical design as these are not features that can be easily upgraded by the homeowner in the future. Meanwhile, exposed concrete and plywood flooring are used in order to keep the price of aspects of the home down that can be easily upgraded by the homeowner to suit their own tastes in the future if they so desire. Adding bamboo flooring, new tile, higher-end appliances and cabinets are all things that can easily be done by a homeowner in the future while increasing the insulation levels and increasing the efficiency of the HVAC system are not easily accomplished by the DIY’er.
Extensive work has gone into the upfront design of the home, including advanced energy modeling, to ensure that the final homeowner is getting the most bang for their buck in all of the key values of the home - design, quality, energy efficiency, health and sustainability.
sales inquiries and future plans
The homes will not be officially listed for sale unit we have broken ground on the project of very close to that date. For sales inquiries and to be put on the list to be notified when the units are listed for sale please complete the short form below.
We are also working on ways to enable the 100K House to be reproduced in Philadelphia and other cities that have tight infill lots. We are considering offering the stock plans for a low fee as well as offering a full development service in Philadelphia to build a 100K House on a lot or your own choosing.
