Small footprint.  Big adventures.


2 bedrooms

2 baths



Our Perian designs might boast the smallest footprint, but what they lack in size they make up for in all of the features of a high performance home – large south-facing glazing, thick, super-insulated walls and roof, a dedicated fresh air heat recovery ventilation, and a panelized construction system that reliably delivers excellent airtightness to keep those drafts at bay and the heat this building naturally and passively retains where it’s needed most, keeping occupants comfortable year round through all kinds of weather.  Designed to meet the Passive House Low Energy Building Standard (requiring 70% less energy to heat and cool than conventional construction), the only other thing little about this home is the amount of energy required to operate it.



Choose between three architectural styles with three corresponding floorplans.  The traditional features a gable roof and an exposed glulam roof beam supporting the roof structure, while the contemporary design features a low sloped roof with clean interior lines.  Both feature an outdoor fireplace, as indoor fireplaces in high performance homes cause air quality and overheating issues.  The “petite” takes away the outdoor fireplace, moves the entry, and simplifies the design.

Whether you need a screened-in porch, a detached garage, or improvements for accessibility, we can help you find the best way to include these into the standard designs.

Building performance is as much as about comfort, durability, and air quality as it is about energy efficiency and material choices.
