Why Choose a BTF Net Zero Home Plan?

BTF Net Zero plans are integrated architectural & mechanical drawing packages. We are the first in the country to offer this pioneering integrated solution.  


Providing Architectural, HVAC, Energy Analysis & Solar PV coordinated & within one drawing package. We've done the engineering for you. 


✔ Under 2,000 SF: Compact, efficient layouts, easier to build & maintain while designed to fit modern needs


✔ Aging-in-place friendly & home office options


Our easy to build designs SAVE you time, money & resources in construction. 

  • Simple, small & timeless architectural designs, make  BTF homes much more cost effective to build than other home designs on the market 
  • Also, no longer do you need to hire a mechanical design firm & architect, for months of site specific net zero design.  
  • Plus, we design around standard building materials too. 


From the quotes we've seen, our BTF Net Zero homes cost the same to build as a typical home. Even donation-funded builders choose our net-zero home designs! 


✔ Used by Habitat for Humanity & Non-Profit Builders Nationwide: Proven performance & cost-effectiveness  

Simple, build-able plans with standard materials & methods - Such as 2x6 walls, double pane windows! 


BTF plans are designed to make fossil fuel free net zero construction EASY. BTF plans are easy to read,  easy to follow & easy to build from. Our plans  are preferred by both contractors experienced with net zero  construction, as well as those new to Net Zero & green building.


 ✔  Reduce labor & material costs while simplifying construction. Forget unnecessary bump-outs, dormers, or false gables, we've optimized exterior shape & window placement 


 ✔ Nearly any site in 35 States: HVAC & Energy modeling designed for Climate Zones 5A through 8

A Place Called Home

 The home is shelter, stable and warm.

A place to gather in snow & storm, 

To relax and play in grass & moss, 

In cozy warmth, that bites the frost.
