Cost estimates are an important consideration when building any new home. Your Habitat Post & Beam material package will typically cost between $65-100 per square foot of living space. This cost is for the materials to complete the weather-tight shell of the home and includes not only the frame, but also exterior walls, "housewrap," siding, exterior trim, Andersen® windows and patio doors, Jeld-Wen® entry doors, and architectural roof shingles (see complete material list). All of these high-quality materials make for a home that is competitive in cost with a custom-built, conventionally framed house that is using high-quality materials, and more economical than many other timber frame and log home packages.
The typical Habitat home is finished for between $200-300 per square foot (including our package cost). This figure will vary depending on the level of finish and the region of the country in which you are building. This cost per square foot average does not include land or land improvements such as septic, well, excavation, lot clearing, and driveway/landscaping.  Adding a garage, walkout (daylight basement) level, extra porches, and other design features such as natural stone fireplaces, walls full of windows, extra patio doors, etc., can increase the cost beyond these estimates.  
Please note that you can make changes to any of the designs without an additional design fee. The material package price changes depending on addition or deletion of materials.
* Prices may increase if you are building in an area with unique engineering requirements, such as high wind (>= 100mph/115Vult), heavy snow loads (>65 psf), or earthquake zone rated above category 2a.

Cost estimates for additions are almost impossible to determine without looking at your specific project. The cost per square foot is highly variable with such small spaces. As an example, windows can make up a considerable portion of the cost for the addition. Most of our standard homes have a window cost somewhere between $5 and $10 per square foot. A 16' x 14' addition with twelve standard size double hung windows and one half-round window for the gable would have a window square foot price of around $40 per square foot. If you replace a couple of the windows with double swing French doors, you could expect an additional $5 per square foot. Because of reasons like these, additions may cost anywhere from $75 to $150 per square foot for our package. Please contact us directly to talk about your specific addition and its cost.
