Project Description

Consultant: Dylan Lamar
Designers:  EkoBuilt

EkoBuilt’s demonstration Passive House was built on a 10-acre property west of Ottawa in 2016. The projects showcases the fundamental simplicity of the PassiveHouse concept – a house built surprisingly affordably with the latest technologies, while also being easy to build and operate.

The house has been occupied for a full year, and we’re all the more convinced of the innate comfort of this incredibly energy efficient and easy to run home.

Come out to visit our 4-bedroom demonstration home. You’ll have an opportunity to find out more about:

  • the real differences between PassiveHouse and conventional homes (and why you can build a PassiveHouse more affordably than you might think);
  • why the 21st century home must be affordable to build and to run.

Why build a conventional custom home, when you can build a Passive House? Discover how supremely healthy, comfortable and affordable a home can be.
